Storage Units
Storage Units are drainage system nodes that provide storage volume. Physically they could represent storage facilities as small as a catch basin 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 depth
· Depth-surface area data
· Evaporation potential
· Ponded surface area when flooded (optional)
· External inflow data (optional)
