Sediment and Water Quality Transport in Urban Watersheds
Research Participation Program
Office of Research and Development
National Risk Management Research Laboratory
U.S. Environmental Protection Agency (EPA)

EPA-ORD/NRMRL-WSWRD-2015-04

Project Description:


Extra Note: Water resources job opening with in Cincinnati, Ohio for someone with a masters or PhD:
A postgraduate research project training opportunity is currently available at the U.S. Environmental Protection Agency’s (EPA), Office of Research and Development (ORD)/National Risk Management Research Laboratory (NRMRL). The appointment will be served with the Water Supply and Water Resources Division (WSWRD) in Cincinnati, Ohio. 
The WSWRD conducts research on microbial contaminants, water treatment technology, urban water management, and water quality controls for the benefit of the nation. 
The research opportunity will include activities such as:
  • Formulation of numerical techniques for simulation of nutrient and sediment water quality transport.
  • Development of initial solution prototype.
  • Testing of prototype with analytical, synthetic, and field study data.
  • Development of production code for SWMM based on prototype experience
  • Preparation of research products documenting methodology and results. 
The research participant will gain:
  • Experience with numerical solution of advection-diffusion-reaction equations
  • Knowledge of overland flow hydrology and numerical simulation of open channel flow hydraulics
  • Experience with object oriented software design
  • Experience developing software in C/C++.

Qualifications:

Applicants must have received a master’s or doctoral degree in civil/environmental engineering, hydrology, environmental science, or other related discipline within five years of the desired starting date, or completion of all requirements for the degree should be expected prior to the starting date.
The program is open to all qualified individuals without regard to race, sex, religion, color, age, physical or mental disability, national origin, or status as a Vietnam era or disabled veteran.

The appointment is full time for one year and may be renewed upon recommendation of EPA and contingent on the availability of funds. The participant will receive a monthly stipend. Funding may be made available to reimburse the participant's travel expenses to present the results of his/her research at scientific conferences. No funding will be made available to cover travel costs for pre-appointment visits, relocation costs, tuition and fees, or a participant's health insurance. The participant must show proof of health and medical insurance. The participant does not become an EPA employee.

Technical Questions:

The mentor for this project is Michael Tryby (tryby.michael@epa.gov).

There was a change in EPA SWMM 5.1 to better represent Weekend vs Weekday Hourly flow patterns

There was a change in EPA SWMM 5.1 to better represent Weekend vs Weekday Hourly flow patterns

Fields for the DWF Tables in H2OMap SWMM and InfoSWMM are:

1. Scenario Name
2. Junction ID for the node that receives the DWF
3. The item – either FLOW, MASS or Concentration (Use Blockedit to just set this at Flow for all Rows) and you should fix your problem.
4. Value – the flow in the units defined in the Run Manager
5. Pattern1 – Can be Weekend, Hourly (Weekday only), Monthly or Daily patterns.  They can be in any order but Hourly only applies Monday to Friday.
6. Pattern2 – Can be Weekend, Hourly (Weekday only), Monthly or Daily patterns. They can be in any order but Hourly only applies Monday to Friday.
7. Pattern3 – Can be Weekend, Hourly (Weekday only), Monthly or Daily patterns. They can be in any order but Hourly only applies Monday to Friday.
8. Pattern4 – Can be Weekend, Hourly (Weekday only), Monthly or Daily patterns. They can be in any order but Weekend only applies to Saturday and Sunday.
9. Alloc Code which is a tag from the DWF Allocator

It used to be that the two hourly patterns were applies as

… the week end flows are generated in the model by multiplying Node DWF x Hourly x Weekend x Daily x Monthly. 

But now

… the week end flows (Saturday and Sunday) are generated in the model by multiplying Node DWF x Weekend x Daily x Monthly. 

… the daily flows (Monday to Friday) flows are generated in the model by multiplying Node DWF x Hourly x Daily x Monthly.

How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM w/ #SWMM5

How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM  w/ #SWMM5

Find the Fraction of Normal Flow Limited in the Flow Classification  Table and copy it to the Link Information Table - the value of FLM can then be Displayed in a Map using  the Map Display command.  In this small example, three links primarily used normal flow and one uses it for a short time. Normal flow only uses the Manning's equation and the link upstream depth, hydraulic radius and cross sectional area to compute the flow.


How to Tell how Long Normal Flow is used in a Link in #InfoSWMM, H2OMap SWMM  w/ #SWMM5
St. Venant equation solution – this is the link attribute data used when the St. Venant Equation is used in #SWMM 5. Simulated Parameters from the upstream, midpoint and downstream sections of the link are used.
Normal Flow Equation – this is the link attribute data used when the Normal Flow Equation is used in #SWMM 5. Only simulated parameters from the upstream end of the link are used if the normal flow equation is used for the time step.
