Dry ponds are found in storage element in the LID TTT.

Dry ponds are a storage element in the Treatment Train Tool.

A Dry pond as a storage element (key parameters)
Stage Storage
Name Important to have a unique name, to connect it with the catchment area
Storage type Dry detention ponds
Bottom elevation (m) This is important to correspond with other components, e.g. when the overflow is coupled to another BMP within a treatment train
Maximum depth (m)
Lined/unlined Unlined (ideally)
Evaporation factor 0
Curves
The Curves table is designed to accommodate the side slopes. The top line begins at 0 m, with subsequent depths in the following lines.
