National_Stormwater_Calculator_Desktop

This is the source code repository for the desktop version of EPA's National Stormwater Calculator (SWC). The SWC is a software application that estimates the annual amount of rainwater and frequency of runoff from a specific site. Estimates are based on local soil conditions, land cover, and historic rainfall records. It is designed to be used by anyone interested in reducing runoff from a property, including site developers, landscape architects, urban planners, and homeowners.

The SWC accesses several national databases that provide soil, topography, rainfall, and evaporation information for a chosen site. The user supplies information about the site's land cover and selects low impact development (LID) controls they would like to use. The LID controls include seven green infrastructure practices. The SWC's cost module allows users to estimate capital and maintenance costs for LID control projects.

The SWC can be downloaded at the offical website.

national_stormwater_calculator_desktop's Issues

Remove year reference in y-axis label

The cost plots have the year 2015 hard-coded in the y-axis label. The year dynamically updates in the title of the same plots. After talking with @JasonBernagros we think we should just remove the year from the label and keep it in the title.

Fix water budget calculation for scenarios with LID controls

To calculate the water budget, the SWC reads from the .rpt file and uses values from two tables. Prior to SWMM 5.1.007, a value in the Flow Routing Continuity table was written as “Seepage Loss”; the label was changed to “Exfiltration Loss” in SWMM 5.1.007 (this link should jump you to the code update made in SWMM: USEPA/Stormwater-Management-Model@cb7eb06#diff-5d4d095c0a2f8544178a80766d4943caL729). The SWC searches for the keyword “Seepage Loss”, but since “Seepage Loss” no longer exists in the .rpt file, it will never find it.

Solution: update to search for "Exfiltration Loss" rather than "Seepage Loss" and use that value in the water budget calculation.

Top plot in rainfall/runoff

The top plot for rainfall/runoff has only rainfall values, even when you only have one scenario. The bottom plot shows both rainfall and runoff values depending on where you’re hovering.

Post Build Instructions

It's been awhile since I've built the Stormwater Calculator. I wanted to get in and refresh my memory on how I put together the installer.

So I cloned the repository and successfully opened the Solution in MSVC 2010. The build failed, however, due to unresolved assembly references. Clearly I'm missing something ...

Would be possible to post build instructions for people with poor memory like me?

Thanks! 😄

Fix strikes associated with topography - moderately steep in costs module

Table 15 in the user's manual shows that the strikes associated with moderately steep topography should be simple = 0, typical = 1, complex = 1, but instead it is being assigned strikes of simple = 0, typical = 1, complex = 1.

Adding a LID scenario may affect the "days per year with rainfall"

While testing the web app, Jason had this comment:

I noticed with the addition of the LID scenario that the "days per year with rainfall" changed in the SWC desktop from the "predevelopment/baseline" scenario, this shouldn't happen.

Google Image Charts deprecated

https://groups.google.com/forum/#!topic/google-chart-api/rZtHTyYgyXI

The desktop was using this API to produce the icons representing precipitation and evaporation stations. Without the API the desktop produces purple circles representing the stations. The actual charts in the desktop are not using this API and are not affected.

Cache BLS data

Consider caching BLS data so we don't risk hitting the BLS API limit.

100% impervious/100% permeable pavement

Sites that are 100% impervious and 100% permeable pavement thrown an error. This is also true on the SWC desktop.

Percent impervious on both web/desktop is written as NaN. Input file:
