To find drying times and areas for underground bowl


I have this model and have tested sun paths and direct sunlight hours, but I want to combine this with water flow simulations to understand the drainage analysis for the bowl which is underground but top open, how can I use this to figure out how and atvwhat point the bowl will dry if rained. I want find areas where it may not dry with morning gains if anyone is able to help.

Thanks in advance :slight_smile:
