Developing HEC-1 Models With Custom Storm Events

This tutorial outlines the method for creating a Project with Custom Storm Event.

The procedure for creating a Custom Storm Event project is basically the same as developing a HEC-1 project using S-Graph. The only difference is that the rainfall uses a custom distribution and the rainfall event is not necessarily associated with any return period. The procedure allows for the user to enter the Rainfall Distribution to use in the analysis as well as the total storm depth. The procedure applies only to S-Graph and not to Clark UH Method.
