Not sure what you call the sandbox apparatus. Can you describe what is this apparatus?

However, the rest of your question seem to imply a method to create heterogeneities during flow with some form of visualisation.

I would suggest to look at this paper:

Transport in Porous Media 2010 Vol: 87(1):335-353. DOI: 10.1007/s11242-010-9687-4 Immiscible Displacement in Cross-Bedded Heterogeneous Porous Media
