The purpose of this data capture was to collect data for modelling used to investigate the response of the estuary to future tidal and atmospheric changes. The model has also been used to investigate the response of the estuarine dynamics to potential management strategies. The work leads on from a previous study which developed an initial version of the Dyfi Model (Robins 2009, hereafter denoted the 2009 Dyfi Model). It was possible to improve the model resolution due to ever-increasing computer capabilities and data storage at Bangor University. There is a need for this Dyfi Estuary study to keep track with technological advances in modelling and to improve the accuracy of the simulations, broadening the possible applications of the model to coastal processes and coastal management scenarios. Further information can be found in CCW Contract science report 1033.

The model is based on a TELEMAC Modelling System which calculates the temporal and spatial variations in hydrodynamics (e.g. elevations, velocities, pressure, density) and sediment transport through a finite-element model grid (an unstructured mesh of nodes connected in a triangular framework) which represents the bathymetry of the area. Input data to the model includes bathymetric data from Admiralty charts and LIDAR data, tidal prediction of sea surface heights, and river flowrate data. Simulations of present-day mean/extreme and future climatic projections have been produced. The project extends three previous modelling studies in other representative Welsh estuaries, namely the Dyfi Estuary, the Burry Inlet, and the Mawddach Estuary (see CCW Science Reports 898a, 898b and 898c).
