EPA Releases Climate Assessment Update to National Stormwater Calculator

EPA Releases Climate Assessment Update to National Stormwater Calculator
WASHINGTON –Today, the U.S. Environmental Protection Agency (EPA) released phase II of the National Stormwater Calculator and Climate Assessment Tool package. The updated calculator includes future climate vulnerability scenarios.

The calculator, a part of President Obama’s Climate Change Action Plan, is a desktop application that estimates the annual amount of stormwater runoff from a specific location. The calculator now includes changes in seasonal precipitation levels, the effects of more frequent high-intensity storms, and changes in evaporation rates based on validated climate change scenarios by the Intergovernmental Panel on Climate Change.

“Climate change threatens our health, our economy, and our environment,” said Gina McCarthy, EPA Administrator. “As part of the President’s Climate Action Plan, this tool will help us better prepare for climate impacts by helping build safer, sustainable, and more resilient water infrastructure.”

The updated calculator includes climate models that can be incorporated into the calculation of stormwater runoff. This adds future climate scenarios to last year’s phase I release, which included local soil conditions, slope, land cover, historical rainfall records.

Users can enter any U.S. location and select different scenarios to learn how specific green infrastructure changes, including inexpensive changes such as rain barrels and rain gardens, can reduce stormwater runoff. This information shows users how adding green infrastructure, which mimics natural processes, can be one of the most cost-effective ways to reduce stormwater runoff.

Every year billions of gallons of raw sewage, trash, household chemicals, and urban runoff flow into our streams, rivers and lakes. Polluted stormwater runoff can adversely affect plants, animals, and people. It also negatively impacts our economy – from closed beaches to decreased fishing in polluted areas. Green infrastructure can reduce the damage caused by climate change by improving water quality in streams and rivers, protecting groundwater sources, and enhancing recreational activities. Using the calculator to choose the best green infrastructure options for an area is an innovative and efficient way to promote healthy waters and support sustainable communities.

Reasons to use the Advanced Force Main Network Support Option in InfoSewer and H20Map Sewer

See the image for the two main reasons but another reason is that you get a better continuity error with this new(er) feature or option in InfoSewer

Surface Ponding and its Impact on Irregular Channels in SWMM5

Surface Ponding and its Impact on Irregular Channels in SWMM5

A few considerations to think about when you are modeling natural channels or irregular channels in SWMM 5:
1. The Maximum depth is limited to the Transect Highest minus the Lowest Elevation
2. If the Maximum depth is reached during the simulation any excess water from the upstream node is either stored at the upstream node or lost as flooded water
3. If the excess water is stored it means you are using the Surface Ponding option in SWMM 5
4. If you using the Surface Ponding option then the depth at the upstream node will increase based on the Excess Flow / Pond Area
5. The Irregular channel is restricted to full flow but if the HGL at the upstream head rises you can get more flow through the Irregular channel as the flood level rises.
6. The flow is thus sensitive to the ponding area

How to Use Qfull in a Map Display in InfoSWMM

 How to Use Qfull in a Map Display in InfoSWMM and H2OMap SWMM

Here is how you can plot the Qfull for a link on the Map Display:
1.      Copy the Qfull Value from the Run Manger Conduit Summary Output Table
2.      Paste it into the DB Table for Conduit Information, You will need to make a new column with a numeric type
3.  The  Map Display will now have a Map Display variable called Qfull or whatever you created
4.      The Map will now show the  value of Qfull or the full flow based on Manning's equation

Snippet of 25 Water Quality Constituents for SWMM 5

This is for students of SWMM 5 who want to quickly have many water quality constituents in their model.  You can copy and paste this snippet to your SWMM5.INP file and change the coverages sections to have 25 Pollutants with Buildup and Washoff Sections.  I hope this helps you in your water quality modeling.
