This set of worksheets automates preparation of an outflow hydrograph from a detention pond based on user-provided information about the inflow hydrograph, the stage-storage relationship, and the outflow control device used for the detention pond.
There are worksheets for the following types of outflow control:
1. Rectangular sharp-crested weir
3. Broad-crested weir
4. Pipe outlet
5. Two-stage, orifice-standpipe outlet
6. Two-stage, pipe-sharp-crested weir outlet
There is also a worksheet that prepares a stage-storage table for a detention pond based on user input information about the pond configuration and size, and a worksheet that prepares a composite inflow hydrograph from up to five user input inflow hydrographs.
