Storage Units in InfoSWMM and SWMM5
Storage Units are drainage system nodes that provide storage volume. Physically they could represent storage facilities as small as a catchbasin or as large as a lake. The volumetric properties of a storage unit are described by a function or table of surface area versus height.
The principal input parameters for storage units include:
- Invert elevation
- Maximum water depth
- Initial water depth
- Depth-surface area data
- External inflow data.
- Infiltration Parameters (optional)
Computed output consists of
- Water depth
- Hydraulic head
- External inflow rate
- Overflow rate
- Concentration of each water quality constituent.
