How to Use the Clark Unit Hydrograph Method in InfoSWMM and InfoSWMM SA

How to Use the Clark Unit Hydrograph Method in InfoSWMM and InfoSWMM SA

Clark’s method derives a unit hydrograph by explicitly representing the processes of translation and attenuation, which are the two critical phenomena in transformation of excess rainfall to runoff hydrograph. Translation refers to the movement, without storage, of … Read the rest
