Abstract: DIVAST (Depth Integrated Velocities And Solute Transport) is a two-dimensional hydrodynamic and water quality model which has been developed for estuarine and coastal modelling by Cardiff University. The original model simulates two-dimensional distributions of surface water currents, elevations and various water quality parameters as functions of time. This paper describes extensions to DIVAST to include 2-D subsurface flow in porous media, sited horizontally adjacent to the surface water domain. This extension to the original model provides an initial step to developing a fully integrated basin wide model for surface and subsurface water flows. Other models that model similar situations are summarised herein. The original method for solving the finite difference equations in DIVAST is briefly discussed, and the extensions to this method are outlined. Initial simulation results are summarised, along with further modifications that will be implemented in the future, including 3-D groundwater flow and GIS linked run-off modelling and visualisation.
