WMS:MODRAT Reservoirs
Checking the Reservoir routing box in the MODRAT Parameters dialog instructs MODRAT to perform Modified-Puls Level Pool routing (reservoir routing) at the confluence point selected. This routing operations occurs prior to the channel routing specified. This requires input of a storage-capacity curve and an elevation-discharge curve for the reservoir to be modeled. When the box is checked, the Define Reservoir button will become active. Clicking the button will open the Detention Basin Calculator; this calculator provides several options for defining the curves needed for routing.
Multiple elevation discharge relationships can be defined in the Detention Basin calculator. WMS will use each elevation discharge relationship to interpolate discharges for all elevations defined in the storage capacity relationship and use those to compute a composite elevation discharge curve for routing.
Reservoir routing will generate a reservoir routing output file from the MODRAT model. A full report of input curves and the inflow/outflow/storage table is included in this file.
