Current projects and collaboration

  • Thames Observatory - The Thames catchment provides a unique opportunity to study the regional environment of a megacity cited within a larger rural catchment, at a number of scales. In addition, a regional scale Thames Observatory would allow a quantitative assessment of: the impact of human induced environmental change on these systems; the strength of any dynamic coupling between physical, human (including the built environment), biological and chemical processes; potential ‘tipping points’ in the system; and the sensitivity and consequences of modifying the state of the natural system. This project is taking the first steps towards building an integrated Thames Observatory by creating the technical infrastructure to deliver quasi-realtime data, modelling and research products in a range of formats.

  • Coastal Evolution - Investigating the influences of oceanic and climatic variables on shaping soft sediment coastlines using the Coastal Evolution Model (CEM). The model initially developed by Murray and colleagues at Duke University, USA, simulates shoreline development in response to deep-water wave climates. The model can also accommodate variable substrate hardness and distributed coastal erosion rates enabling simulation of coastline evolution when sediment is supplied from an eroding shoreface. A framework was created to enable ensemble modelling of wave climate and other initialising parameters, factors which are likely to vary with climate change. This project is currently focused on the spiral natured Holderness coastline, Lincs, UK.

  • Decadal Scale Landscape Evolution - The CLiDE environmental modelling platform is a geomorphological simulator that allows a variety of Earth systems, and their interactions, to be explored. The platform includes a variety of modules, representing key terrestrial Earth system components, which may be switched on/off as required. This versatility allows CLiDE to explore a variety of scenarios at a range of timescales. CLiDE may be used to further our understanding of a particular system or to simulate the impacts of changing driving conditions on terrestrial systems. The latter is particularly relevant to the current, unprecedented, rapidly changing environment we are now experiencing. This year the project is focussed on the representation of physical anthropogenic processes on groundwater, surface water and sediment fluxes in landscape evolution models.
