The S10 demonstrates, on a small scale, the relationship between rainfall and runoff from catchment areas of variable permeability, and the abstraction of ground water by wells, with or without surface recharge from rainfall.
The S11 provides a small-scale demonstration of the hydrological principles of ground water flow, and their relevance to certain engineering constructions. Particularly suitable for the study of sub-surface water flows.
This improved version of the Armfield Sediment Transport Demonstration Channel enables the demonstration of the full range of bedforms that arise in a mobile bed as the flow and/or slope are increased.
