Organic Model Problem

Hello

I need to model a stone cascade. The stone has an organic look to it. I have attached a photo. The cascade is about 2m wide. I really am stuck about where to start, any advice appreciated!


Thanks

looks like the flow of water is modified by some obstaces on bottom
1 - make some obstacle shape make it a obstacle
2 - use the fuild simulation to let water flow over that obstacle

and run the simulation
select one frame that looks like you photo

happy bl
