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.

Hello Trevor, thank you for your response and please pardon me that I didn't reply sooner. So to run this I am thinking of running a column test with the same material used in berm compacted to desired density, where the sample will be compacted in pvc mold and to it moisture content sensors inserted placed equally along the mold to note down the temperature spatially after putting it into chamber where I can control the desired drying based on weather. By doing so I can noted down the moisture content along the depth which I am thinking of using it as initial condition. Please let me know if this works or correct way to input in the initial condition in GeoStudio seep w

Hi @DivyanshRaunak, you can initialize the domain with a spatial function if that's what you prefer. You can go to Define>Spatial Functions>Pressure Head
Then click Add and you can put in your pressure head data points and select your interpolation method
Then you can go to the Define Project dialog and select spatial function in the initial head dropdown, and select the spatial function you defined under that.
