HEC-HMS modeling Reservoir with both spillways and pumps
HEC-HMS modeling Reservoir with both spillways and pumps
(OP)
I am looking to model a watershed with a reservoir. In addition to the direct precipitation runoff, the reservoir is also receiving pumped inflow from nearby wastewater facility.
The reservoir has an emergency spillway weir and also a pump discharging at a constant flow rate (apprx. 15cfs).
Anyway to include the pump discharge and the spillway weir at same time in the model?
I don't have any details on the pump other than its activated once the normal pool is exceeded by 1-ft and its constant cfs.
Can I add the constant discharge from the pump to the rating curve for the spillway weir?
