Hydrology Apparatus — MOE Lab Tender Details

Hydrology Apparatus

For students to study hydrology, including rainfall and movement of water over land and rivers.
To include Permeable Medium  – Washed sand, graded 0.5 mm to 1.5 mm (nominal 1 mm)

Experiments
Investigation of rainfall/run-off relationships for dry, saturated and impermeable catchments of various slopes (surface run-off only)
Effect of interflow on outflow hydrograph surface runoff (plus groundwater flow)
Simulation of multiple and moving storms
Measurement of cone of depression for a single well and comparison with theory interaction of cones of depression for two adjacent Wells
De-watering of excavation sites by use of Wells
Flow from a well in a confined aquifer
Demonstration of watersheds for a simulated island with rainfall and well flows
Sediment transport and meanders in simulated rivers
Studies of scour around simulated bridge piers
