Problem Description

What rainfall distribution types are used in CulvertMaster?

Details

The ‘SCS Peak Discharge’ method in CulverMaster is taken from TR-55, Urban Hydrology for Small Watersheds, where it is called the ‘Graphical Peak Discharge Method’. TR-55 only publishes data for four different rainfall distributions (I, IA, II, and III), so that is the extend of what is used in CulvertMaster.

It is possible to add your own rainfall depths. You can enter these in the Rainfall Depth fields:

For a more detailed analyses that allows you to route a hydrograph generated from any storm event through a culvert, we recommend another Bentley product called CivilStorm.
