Hydrological & Water Quality Modelling

We have expertise and experience in rainfall-runoff modelling (including use of HYSIM and PDM), river flow record analysis, surface water and reservoir yield and reliability analysis, low flow analysis and groundwater modelling using 1D, 2D and 3D models. Our hydrological expertise also extends to water balance studies, development of catchment, river and reservoir inflow time series, flow duration and flow frequency analyses, reservoir control rule development and consumptive use estimation. We also have expertise covering investigation of pollution sources, pollutant transport modelling and analysis of water quality impacts on the human and ecological receptors. Our capability and technical competences in water quality assessments cover a wide range of topics including: dye tracing experiments to determine time of travel and residence times, dispersion studies, analytical modelling, hydrodynamic modelling, aggregated dead zone modelling and single (or multi-dimensional) advection-dispersion-kinetics modelling.
