Morphodynamic Modelled Outputs for the Dyfi Estuary dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS115311 A 4-month study, conducted by Bangor University for the Countryside Council for Wales (CCW), to develop a high-resolution morphodynamic model of the Dyfi Estuary and surrounding area. 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.
