Thank you very much for your reply.

The model would be for an hypothetical surf parc where artificial waves can be made and the question would be if sand could be used for the aesthetics but also if this sand within the surf park can be used for research purposes. To my knowledge, the sand would be the the floor bed on top of the surf parc. 

Does this give a bit more insight on my problem? Would you still say that it would be too difficult to build
