Water Quality Modelling

Roger has worked extensively on a range of hydro-environmental modelling studies, including modelling water quality, sediment transport and morphological processes, in river, estuarine and coastal waters.

His key activities in this field Include: (i) continuously developing, refining and applying his computational model DIVAST (Depth Integrated Velocities And Solute Transport) for predicting a range of water quality and sediment transport parameters, based on the US EPA formulations and for cohesive and non-cohesive sediments; (ii) supporting consulting companies and regulatory stakeholders in mounting and applying models for predicting a range of key water quality indicators, such as: flushing, salinity, temperature, faecal indicator organisms, dissolved oxygen, nitrates and phosphates etc.; (iii) supporting companies and stakeholders in modelling sediment transport fluxes and concentrations, both for cohesive and non-cohesive sediments, and estimating morphological changes associated with long term bathymetric changes; (iv) contributing to the management of water quality in rivers, estuaries and coastal waters through engagement with water companies and regulatory authorities; (vi) publishing journal and conference papers and delivering presentations on water quality and sediment transport modelling; and (vii) engaging in TV and media interviews with regard to water quality and sediment transport processes, such as the Severn Barrage hydro-environmental impacts (BBC).
