So you bought a water model, now what?

$

By Mike Rosh (edited by Frank Conforti)

With over 14 years of experience in the water industry as an Environmental Engineer and as a volunteer firefighter, I have a passion for water and I think it shows.  Let’s “dive” in shall we?

So, you just bought a water modeling solution and want to jump in. Where to begin? First, take a deep breath and establish your goals and objectives:

What do you need to do?

What do you want the model to tell you?

Where is your data stored?

Who controls your data? 

My advice: start small. Document the goals of your organization and put together your core team to see it through. That way you can measure the  success by short, medium and long term goals.  As tempting as it is, don’t start with “I want to reduce my energy consumption” as your initial goal (that’s a great long term goal though). Instead, short term goals should be based upon building your model, here are some examples:

  • Collect/locate paper maps, CAD and GIS data

  • Collect CIS (metering) data

  • Find Average Day demand from metering data

  • Collect elevation data (TIN, Raster, etc). Note the accuracy, for example 1m or 10m?

  • Gather pump curves for all pumps

  • Gather tank specs

Note, digitization of paper documents and refinement of data may be needed.  It’s much easier to do this before you get started building the model and someone is therefore waiting on it.

Some Medium term goals are:

  • Build the model

  • Assign all elevation, demands, pump curves and tank data

  • Determine demand patterns (notice this isn’t in short term, this can take some time and understanding of the system)

  • Start calibrating the model

Example Long term goals:

  • Calibration of model

  • Developing an Extended Period Scenario

  • Hooking SCADA to the model

There are many goals for different organizations please feel free to add your own to this list, but have a well-defined set of goals before you start. Trust me; you’ll be glad you did!

Once you have your goals, you’ll need to think about the data you’ll need to obtain them, the topic of my next article.  Stay Tuned!

From Splitting Wood to Knowledge Executive

$

If you're an engineer in the realm of hydraulic modeling and design and you use Bentley software, you may know me from my interactions on the Hydraulics and Hydrology Community. I've enjoyed nearly a decade of helping other users in their success with our water modeling products and ultimately at sustaining infrastructure. With over 1700 forum posts going back to 2008 and over 10,000 support incidents handled, you might assume my previous job was a hydraulic modeler, site design engineer or perhaps a CAD Administrator.

Not quite. Picture this - late November of 2005 in New England, USA. It's 8 AM and where am I? Am I amongst the quiet tapping of keyboards, the glow of fluorescent lights, the murmur of phone conversations? No, I'm out in the woods, icy leaves crunching beneath my feet, breath visible in the 20 degree (F) late autumn morning air as I trudge up a hill. With paper bag lunch in hand, I'm ready to be immersed in the sounds of heavy machinery. I had joined my friend's father's tree service company. My day consisted of loading logs into a wood splitter, hauling the remains of downed tree trunks, shoving branches into an industrial wood chipper, and so forth.

Sure, having recently graduated with my degree in Computer Information Systems, this was a bit of a compromise and understandably temporary, but I quite enjoyed it.  On top of the endorphin rush from getting a good workout each day, each customer site presented a new and interesting situation and there was a feeling of satisfaction after completing each task.

This only lasted a few months. After joining Bentley Systems, I quickly found that the role of Technical Support Engineer kept me engaged in a similar way. Each incident from a user (a question or a problem) presented a new and interesting challenge and that same feeling of satisfaction upon resolution. Being able to figure out challenging engineering problems and hear the appreciation from the user was (and still is) a major driver for me to hone my skills and achieve a deeper and deeper level of knowledge.

My workstation as a Technical Support Engineer

 

My lack of engineering background didn't scare me away from the many new things I had to learn in the realm of hydraulics and hydrology. My father was an engineer and I had some interest in the subject. That addicting sense of accomplishment from solving a user's puzzle question kept me going, eventually leading to Bentley Communities.

When Bentley Communities was launched around 2008, it wasn't long before I started contributing there as well. If I saw a user's question and I knew I could contribute (if not answer it quickly), I pressed that shiny red button. Today as a manager of the same H&H technical support team, I still have the same desire to help out where I can, but I also work to motivate the rest of my team to also place emphasis on our growing Community.

I have also always been a big believer in the importance of documenting knowledge. Now, I'd like to think I still have a decent enough memory, but let's be honest, it's impossible to remember every answer, every solution and every facet of our products. I've always found that the mere act of writing something down gave me a much better chance of remembering it later, or more importantly, remembering that I had written *something* about that. So, before the age of Bentley Communities, I made it my personal mission to document as many knowledgebase articles as I could. When Communities came along, I seeded our Wiki with several articles on some popular topics. (Someexamples of early articles) This is now the Support Solution section of the community and includes most of the relevant content from our legacy Knowledgebase.

Documenting the solution to problems and answers to questions presents a major efficiency benefit both to our users as well as the technical support team. Users of the software can search for and find answers without having to contact technical support. When questions do come to the Support team, that knowledge can similarly be harnessed and reused, often preventing unnecessary delays from having to research something that someone else had already spent time on.

Answers to questions and solutions to problems are one thing, but did you know that the H&H Community Wiki also has a library of articles detailing the changes and new features introduced with each major product release for the past five years? Even if you don’t currently have any questions about your H&H product, reading these articles can help you make the best use of your investment or help you decide if it’s time to upgrade. You can find links to these “What’s new?” articles from the main index here (scroll down to the product of interest).

This years-long culture of documenting knowledge has led us to a fairly mature collection of content. Very often I am asked to help with something and a ghost of a memory pops in my head, telling me "Check the wiki! It's documented there!". More often than not, this intuition proves true and low and behold, the information is right there in a Support Solution article.

So, I suppose this focus on knowledge has in part led me to the seemingly appropriate title of Knowledge Executive, bestowed upon me this year. Things have certainly come a long way since splitting logs!

If I had continued doing tree work, maybe I would have created a database of strategies for taking down a tree depending on its species, height, health and proximity to buildings and power lines?

Why bother using models in operations

$

“We don’t need models to run the water distribution system. We have SCADA to tell us what is going on.” This is a common answer we hear from water distribution system operators when we talk with them about how models can help them. They are familiar with their SCADA system and may feel threatened by something new.

 

But there is a lot of value that operators can gain from integrating modeling with their normal SCADA system operation. Some questions you may ask the operators are:

 

“How can you predict how much energy you are going to use if you run the system the way you plan? Wouldn’t you want to check out some possibly better ways?”

 

“What happens when there is a power outage at one of your pump stations and you need to change system operations? Wouldn’t it be great to be able to analyze what’s going to happen in the system as a result of your emergency response.”

 

“There is going to be a big concert/sporting event in your system tomorrow. Wouldn’t it be great to simulate what’s going to happen before the event occurs?”

 

“You only have flow meters and pressure gages at a few locations in your system. Wouldn’t you want to know what the flow and pressure is pretty much everywhere in your system?’

 

“They are going to be doing a big shutdown tomorrow for maintenance. Wouldn’t you like to be able to simulate that shutdown before you have any bad surprises?’

 

These are just a few of the situations where water distribution models can help water distribution system operators. Models can give operators the kind of support they would like when making operational decisions. With WaterGEMS’ SCADAConnect Simulator, an operator, with some minimal help from a modeler setting things up, can have a powerful tool to enable him/her to make better decisions. The technology is now available and sufficiently mature to make it happen.

“Life is what happens while you’re busy making other plans.” – John Lennon

 

Jesse Dringoli did a great job explaining how he got into his job.

 

http://communities.bentley.com/products/hydraulics___hydrology/b/hydraulics_and_hydrology_blog/archive/2015/09/04/from-splitting-wood-to-knowledge-executive

 

I decided I would try to do the same. The problem is that I’m a lot older than Jesse and so this blog is going to be long. You’ve been warned.

 

Why am I qualified to write this blog? I figured that you learn a lot by making mistakes and I’ve probably made more than most people in our industry. I guess that qualifies me to write a blog.

 

So, how did I get here?

 

I was always pretty good at math so I became a math major at King’s College in Wilkes-Barre, Pa. But along the way I became very interested in the environment. I had grown up in a poor coal mining town in the mountains of Pennsylvania. It was pretty much an environmental disaster. We had raw sewage running in the gutters along the road which ran into the creek which ran into the river, our drinking water came to us directly from the reservoir in the mountains with no treatment, there were strip mining pits around our town which were used as open dumps and don’t get me started on air quality. I wanted to do something about these problems and considered going to graduate school in environmental engineering.

 

Problem was that I was about to be drafted to go to Vietnam (and probably be killed), so why worry about graduate school. However, I flunked my draft physical because of my bad heart (mitral valve prolapse) and graduate school became an option.

 

Because I didn’t have an engineering undergraduate degree, most schools wouldn’t consider me unless I started as an undergrad. Vanderbilt Univ. was willing to let me into grad school and I jumped at the chance. They felt my math and physics background was good enough (I got 99 percentile on my math GRE test.) The only undergraduate course I had to take was a self-paced Fluid Mechanics class and I completed it faster than any student ever did. I loved that stuff. Gradually I caught up with the other students and finished up my course work quickly.

 

After grad school, I got a job as a research civil engineer for the Army, Corps of Engineers, at their main research lab, the Waterways Experiment Station in Vicksburg, Miss. I finished my dissertation there, “Viscosity Stratified Flow to a Line Sink” (think dredged material flowing over weirs). I got a great deal of experience working on a wide range of projects from a water distribution master plan for the island of Guam, to a pipe break analysis study for New York City, to preparing guidance on designing out-houses at Corps recreation areas. I developed a system for coming up with good cost estimates for project at the planning level with limited information, developed the first multi-objective water distribution system optimization program (WADSIO) and worked on the Washington, DC water system. I became a wizard at FORTRAN programming (which nowadays is like speaking fluent Latin). While with the Corps, I wrote my first book, “Analysis of Water Distribution Systems.”

 

I was contacted by the City of Austin, Tex. about working for their water and sewer utility. I turned them down but taught a workshop there. They kept pursuing me and I finally accepted a position there as the senior engineer working on their modeling in the planning group. It was a nice experience working on the owner’s side of things and it gave me a great perspective on how design decisions are really made. Eventually, my boss moved over to the operations side and took me with her as manager of water distribution operations--more valuable experience.

 

One day, I saw an ad for the executive director of the regional sewer authority back home. (Yes, they no longer discharged raw sewage into the river but they still had problems.) Surprisingly, they hired me and, at a pretty early age, I became the executive director of a sewer system serving about 200,000 people. We took one of the worst operations in the state and were winning awards in a couple of years. But the job wasn’t just technical. (I didn’t get to do much hydraulic modeling in that job.) Instead, I had to deal with regulators, neighbors, the union, the media and, worst of all, politicians. As I was approaching a nervous breakdown, I realize I wasn’t cut out for this kind of work. I wanted to get back into the technical side of engineering and operations. But I also liked teaching.

 

Fortunately, Wilkes University was looking for someone to start up their environmental engineering program and that suited me fine. With limited resources, we built a fine program with a strong practical bent that received ABET accreditation and it still going strong. I really enjoyed working with the students and I still serve as an advisor on senior projects. Along the way, I was approached by Haestad Methods to develop training material and teach workshops for them. So, whenever Wilkes was on vacation, I was on the road teaching about water distribution modeling. I got to see the insides of a lot of airplanes (and they all look pretty much the same) and I met a lot of great people.

 

At this time, American Water had just bought the regional water supply system where I lived and was looking for an engineering manager for the Wilkes-Barre/Scranton system (serving about a half million people) and an assortment of smaller systems around eastern Pennsylvania. I took the job and we did a lot of great projects. It was nice to apply hydraulic models from the user’s side in additional teaching about them.

 

Over the years, John Haestad (i.e. Haestad Methods) would call me an offer me a job and I would turn him down. Finally, one year he made me an offer I couldn’t refuse and I became Vice President of Engineering for Haestad Methods (a company that did no engineering). With my background, I think I brought a lot to the software development team as well as continuing to work on training, and research.

 

After a few years, Bentley Systems bought Haestad Methods and I ended up as a product manager on the hydrology and hydraulics team. I work with a great group of people and have been blessed to have excellent supervisors like Bob Mankowski and Gregg Herrin who keep me going in the right direction but don’t micro-manage me. What do I do anyway? Well, when I worked for the Corps of Engineers, the final line on every job description said “Performs other duties as assigned”. That pretty much sums up what I do at Bentley. When something needs to get done, I try to do it.

 

Along the way I’ve been involved with a bunch of professional committees and publications through AWWA, ASCE and WEF. You’ll find my name in a lot of manuals of practice and similar publications. I served as editor of the Journal of Environmental Engineers and have been associate editor for the Journal of Water Resources Planning and Management for some time now. Among my bigger professional thrills were being the breakfast keynote speaker at the Water Distribution System Analysis symposium in 2013 and being named as one of the 50 “Movers and Shakers in the Water Industry” over the last 50 years by Water and Wastes magazine.

 

I’ve come a long way from a skinny, funny-looking kid  to become a skinny, funny-looking old man. I hope, that through Bentley, I can keep on helping people for a long time to come.

 

Here’s what I do in what little spare time I have and what I looked like when I got my Ph.D. .

 

 

 

The Cloud

When I started working with computers, we loaded punch card decks into a mainframe. It wasn’t long before people realized that the processors in the computer were being underutilized and we started “time sharing”.

 

With time sharing, you work from a remote machine where you enter data and lay out a run. You then upload it to the main computer system where your job is run. Then you download the results to your local machine. You are charged for data storage and processing time.

 

After a while, desktop computing became popular and we moved away from time sharing.

 

Now we have “the cloud”. With the cloud, you work from a remote machine where you enter data and lay out a run. You then upload it to the main computer system where your job is run. Then you download the results to your local machine. You are charged for data storage and processing time.

 

The more things change, the more they remain the same.

IDF-CC Tool is a web-based computer tool for generating Intensity-Duration-Frequency (IDF) curves and assessing the impact of climate change on the precipitation design storms. It is available for free and is hosted by the University of Western Ontario.  IDF-CC Tool can be applied all across Canada. It has three components:

  • A library of precipitation data from over 700 Environment Canada rain stations with an option to add user supplied data for existing or additional stations. Stations can be selected via a GIS style interface. After selecting a rain station of interest, users can view information on that rain station, including the length of the data record.

  • A utility to calculate IDF curves for durations of 5 minutes to 24 hours and return intervals ranging from 2 to 100 years. The Gumbel distribution and the method of moments are used to estimate IDF parameters. Output is produced as data tables, plots and interpolation equations.

  • A tool to calculate future IDF curves utilizing user selected list of 22 Global Climate Models (GCMs) and Representative Concentration Pathways (RCPs) scenarios.

 

The site requires a registration to obtain an account. Results can be generated for an future time  period  up to the year 2100 based on 22 GCMs that  simulate  various climate  conditions to local rainfall  data and three  future climate  scenarios  ranging  from  low to high severity. The IDF CC tool adopts an equidistant quantile-matching (EQM) method for updating IDF curves, developed by Srivastav et al. (2014), which can capture the distribution of changes between the projected time period and the baseline period (temporal downscaling) in addition to spatial downscaling the annual maximum precipitation derived from the GCM data and the observed sub-daily data.

 

To create IDF curves for future climate change conditions, users can select a 20-year projection period for any time between 2006 to 2100 using single or multiple GCM or GCM ensemble options. After selecting these options, the tool will automatically downscale GCM results and apply GCM results to the local rain station data, providing future IDF curves in table or graphical format; allowing the user to compare the impacts of multiple RCP scenarios and rainfall return periods, and to compare historical IDF curves to these updated curves.

 

In the example below, the total precipitation for the 2-year event as determined from the historical data is compared to the projected precipitation as determined from scenarios RCPs 2.6, 4.5 and 8.5 for durations of 5 minutes to 24 hours.


 

 

US EPA Stormwater Management Model Climate Adjustment Tool (SWMM-CAT)

Download at: www.epa.gov/water-research/storm-water-management-model-swmm

 

SWMM-CAT is a software tool that allows future climate change projections to be incorporated into the EPA Storm Water Management Model (SWMM). SWMM is a dynamic rainfall-runoff-routing simulation model used for single event or long-term (continuous) simulation of stormwater runoff quantity and quality from primarily urban areas. The tool can be used with commercial software packages that are based on SWMM.

 

SWMM-CAT provides the linkage between the EPA’s Climate Resilience Evaluation and Awareness Tool (CREAT) downscaled climate change estimates and localized monthly adjustment factors to the hydrologic parameters used by SWMM. On a monthly basis

  • Precipitation,

  • Evaporation, and

  • air temperature

 

may be adjusted according to one of three user selected climate change outcomes. SWMM-CAT automatically updates the SWMM input file.

 

CREAT uses statistically downscaled General Circulation Model projections from the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project Phase 3 (CMIP3) archive (Meehl et al., 2007) as the source of its climate change data. SWMM-CAT provides a set of location-specific adjustments that were derived from global climate change models run as part of the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project Phase 3 (CMIP3) archive. These are the same climate change simulations that helped inform the United Nations Intergovernmental Panel on Climate Change in preparing its Fourth Assessment report (IPCC, 2007).

 

In the figure below adjustment factors for precipitation depths (expressed as percent increase) are presented for return periods of 5 to 100 years for Wilkes-Barre, Pennsylvania.
