Rain Gages supply precipitation data for one or more subcatchment areas … Read the rest
Refactoring the SWMM 5 Help File – Groundwater in SWMM5
Groundwater in SWMM5
| Aquifers |
Aquifers are sub-surface groundwater zones used to model the vertical movement of water infiltrating from the subcatchments that lie above them. They also permit the infiltration of groundwater into the drainage system, or exfiltration of surface water from the drainage system, depending on the hydraulic gradient … Read the rest
Refactoring the SWMM 5 Help File – Hydrology in SWMM5
Hydrology in SWMM5
| Hydrologic Modeling Features |
SWMM accounts for various hydrologic processes that produce runoff from urban areas. These include:
| · | time-varying rainfall |
| · | evaporation of standing surface water |
| · | snow accumulation and melting |
| · | rainfall interception from depression storage |
| · | infiltration of rainfall into unsaturated soil layers |
| · | percolation |
