Advanced Hydrology Study System
1. A self contained floor standing apparatus for hydrology and fluvial geomorphology demonstrations, comprising:.
A 2m x 1m stainless steel tank, tiltable using a dual linked jacking
system
8 stainless steel spray nozzles mounted on an adjustable height gantry
A stilled tank providing a formed flow river inlet
Two flowmeters (3L/min & 5L/min) to measure and adjust the inlet
flows
An outlet tank allowing both water and sediment flow to be measured
Two French drains, two well points and 20 manometer tapping points
linked to a manometer bank
A large plastic sump tank plus a recirculating pump
2. Experimental capabilities include:
Run-off hydrographs from model catchments
Draw-down curves for one well and two well systems
Ground water flow and hydraulic gradients
Model stream flow in alluvial material
Formation and development of river features over time
Sediment transport, bedload motion, scour and erosion
3. A version is available with instrumentation to measure both water and
sediment run-off in real time. The package included data logging and
educational software, (requires a customer provided PC)
The unit comprises a sand tank, made of stainless steel, measuring 2
metres by 1 metre. Water may be input to the sand tank from spray
nozzles located above the tank (simulating rainfall), from an inlet tank
simulating a river flow or from two french drains buried in the sand at
either end of the tank. The water is output either from an outlet tank
and flow measurement system located at the end of the main sand tank,
from one or both of the two wells located in the tank, or one or both of
the French drains.
A large plastic sump tank is located under the sand tank
Determination of run-off hydrographs from model catchments including
multiple storms, moving storms, effect of reservoir storage and land
drains
Construction of draw-down curves for one or two well systems in a sand
bed
Hydraulic gradients in ground water flow .Investigation of model stream
flow in alluvial material
Formation of river features and development over time
Sediment transport, bedload motion, scour and erosion
Stilled inlet tank provides developed river flow conditions, allowing
the full length of the tank to be used for river simulations
Novel outlet tank design for water flow and sediment flow measurement
Stainless steel sand tank
Dual jacks provide adjustable tilt
Adjustable spray nozzle height
Use of fine grade sand allows detailed feature development
Single grade of sand for all defined demonstrations, no need to change
the sand
Control and measurement of inlet flows
Flexible configuration allows a wide range of simulations
Flexible configuration allows a wide range of simulations
Computer data logging option for sediment and water outlet flow
