A self contained floor standing unit consisting of a water reservoir and a tank for sand with overhead spray nozzles that simulate rainfall both stationary and moving. It is for studying hydrology principals including rainfall, throughflow and the movement of water over land and rivers.

Permeable medium. Sufficient for use in the H313 Hydrology Apparatus (Approx 800kg).

For comprehensive study of hydrology. Simulates rain and moving storms over a permeable medium. Includes an inclinable catchment area with central tappings to measure water table profile. Ideal for group study.

Permeable medium. Sufficient for use in the H312 Permeability Tank. (Approx 250kg).

Clearly shows flow through permeable media. See flow lines and trace flow patterns. Make models of sheet piling building foundations and simulated dams. Self-contained with large range of possible experiments.

A self-contained bench mounting apparatus for studies into the settling characteristics of suspended solids and the display of wall effects.
