Problem

Can the Santa Barbara Unit Hydrograph (SBUH) method be used for catchment runoff calculations?

Solution

Bentley PondPack

PondPack supports SBUH - simply select it from the "Unit Hydrograph Method" dropdown, after selecting Unit Hydrograph as the Runoff Method:

Bentley CivilStorm and SewerGEMS

Currently, CivilStorm and SewerGEMS do not directly support the SBUH method for catchment runoff calculations. (Enhancement # 317394)

As a workaround, if you can externally compute the runoff hydrograph (for example if you have PondPack but want to use CivilStorm), you can insert it (via copy/paste) into the program using the User Defined Hydrograph option in the Runoff Method dropdown in the catchment properties.
