Water Flow Analysis

Hello I am beginner in grasshopper I am trying to derive a concept by doing a water flow analysis on a surface and then want to bake those curves into polylines… I have seen videos on youtube showcasing this but those analysis is flowing water from top to bottom I want to flow water on a plane surface … I also want to add obstacles in between and then run the analysis to get the pattern for the same…I have attached the image representing my concept… Thanks in advance!!

Water Flow on Surface

Is there any way to calculate the rain runoff for any given surface (imagine a simple dual pitch roof for example)? I have tested several plug-ins like Mosquito and alike. The drain directions (flow paths) are good on most of them, but I haven’t found a solution which will calculate the amount of water at the drainage points. I am not posting any geometry, because my question is more or less general. Thank you in advance guys!
