SWCC curve under unsat condition
Does SEEP/W under unsat condition takes drying into consideration or somehow we can input initial water content before running storm event on the berm. My concern after storm event the berm goes drying phase between the two storm events. So to run transient analysis how we can input the initial volumetric water content so that the curve starts from reduced initial volumetric water content for the next storm event.

Hi @DivyanshRaunak, there are several ways to initialize the domain in a transient analysis. You can run a steady state analysis, draw a piezometric surface, or define a spatial function and then run your transient analysis.
In your case, you could initialize your domain for before both storms using any method, then run a transient analysis with a boundary condition that models two storms close together. Here you can see an example of a boundary condition for a single flood event, but you could easily make this boundary condition model two storms however many days apart you'd like.
Does that make sense? Please let me know if you have any other questions.
