Estimate Pond Discharge
Calculate Reduced Peak Discharge from a Known Retention/Detention Pond Storage Volume
Qi - Peak inflow rate into the basin
Vs - Storage volume of stormwater pond
Vr - Volume of runoff in the inflow hydrograph
Ti - Time base (duration) of inflow hydrograph
Tp - Time to peak of inflow hydrograph
Qo - Estimated peak outflow rate
