The objective of this study was to develop an innovative spreadsheet-based runoff calculator that rapidly estimates stormwater runoff from ground-mounted solar PV sites. The calculator is built on a 2-D hydrologic model (Hydrus-2D/3D) calibrated and validated using experimental data from five ...
Units for stormwater detention calculator: cm=centimeter, ft=foot, gal=U.S. gallon, gpm = U.S. gallon per minute, km=kilometer, m=meter, min=minute, s=second.IntroductionCommunities usually have guidelines stating that stormwater runoff peak discharge at some location following development cannot...
The app includes NDS’ complete product catalogs for drainage, stormwater management, irrigation and flow management. It features an easy-to-use calculator that determines runoff in gallons per minute and cubic feet of water per second as well as require...
Additionally, the National Stormwater Calculator (SWC) developed by the US EPA is a tool for hydrological measurements of small sites at specific locations in the USA and can estimate the annual volume of rainwater frequency of runoff, retention, and control based on soil, land cover, evaporation...
To determine the amount of runoff that will be generated, the Equivalent Runoff Unit (ERU) is calculated. The ERU is the average impervious area of all the single-family homes in the city. Each single-family home owner pays the cost of one ERU as stormwater fee. Fee for commercial propert...
Low impact development (LID) refers to a comprehensive land planning and engineering design approach to managing stormwater runoff that emphasizes conservation and the use of on-site natural features to protect water quality. According to the nonprofit Low Impact Development Center, Beltsville, Md. (...

(seeTable 3) were assigned based on each municipality's soil group. The soil groups affect how much rainwater infiltrates the ground, changing the amount of runoff that will be generated. Hydrologic soil groups were determined using the NRCS table and the EPA Stormwater Calculator soil maps (...
The update to the National Stormwater Calculator will allow local governments to consider how runoff may vary based on both historical weather and potential future climate. The calculator's stormwater estimates were previously based on local soil conditions, slope, land cover and historical rainfall ...
The U.S. Environmental Protection Agency National Stormwater Calculator (NSWC) simplifies the task of estimating runoff through a straightforward simulation process based on the EPA Stormwater Management Model. The NSWC accesses localized climate and soil hydrology data, and options to experiment wi...
