Refactoring the SWMM 5 Help File – RDII in SWMM5
RDII in SWMM5
Unit Hydrographs (UHs) estimate rainfall-dependent inflow/infiltration (RDII) into a sewer system. A UH set contains up to three such hydrographs, one for a short-term response, one for an intermediate-term response, and one for a long-term response. A UH group can have up to 12 UH sets, … Read the rest
Refactoring the SWMM 5 Help File – SWMM5 Introduction
| Introducing EPA SWMM5 |
The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate … Read the rest

Snowmelt in SWMM5
| Snowmelt |
Snowmelt parameters are climatic variables that apply across the entire study area when simulating snowfall and snowmelt. They include:
| · | the air temperature at which precipitation falls as snow |
| · | heat exchange properties of the snow surface |
| · | study area elevation, latitude, and longitude correction. |

Refactoring the SWMM 5 Help File - Routing in SWMM5
Flow routing within a conduit link in SWMM is governed by the conservation of mass and momentum equations for gradually varied, unsteady flow (i.e., the Saint Venant flow equations). The SWMM user has a choice on the level of sophistication … Read the rest
