Hydraulics Laboratory

The hydraulics laboratory is furnished with two well equipped flumes. The smaller is 10m x 0.3m x 0.45m and the larger 22m x 0.75m x 0.5m. Both flumes use a constant head delivery system, velocity measurement facilities include both Acoustic Doppler Velocimeter (ADV) and Laser Doppler Velocimeter (LDV).

Campus Monitoring Equipment

Meteorological monitoring


Two automatic weather stations provide measurements of rainfall, wind speed, wind direction, air temperature, relative humidity, solar radiation and soil temperature. Data is logged with a ten minute sampling interval. The weather stations are placed so that comparisons can be drawn between exposed and sheltered locations.
Streamflow monitoring


Automatic water level recorders provide measurements of stage associated with six streamflow measuring structures. Data is logged with a five minute sampling interval. Figure 3 shows one of the structures - a two-stage rectangular notch weir. The structures have been calibrated in-situ using gulp injection dilution gauging. Figure 4 shows flows at all sites during January 2000 (compare with rainfall data above).
Modelling Software

Various numerical modelling codes have been developed for solving flow and transport equations within the research group, in particular, in the fields of river engineering and groundwater (e.g. PARADIGM: a groundwater code developed for solution of 3D matrix flow and flow within 2D interacting fault planes). These models are under continuing development as exciting new modelling challenges arise. The models are available for application and development by any researchers in the Sustainable Water Management Group, they are not marketed as commercial software.
