Terrestrial Currently managing the Dynamic Environment Sensitivity to Climate Change (DESC) project, which seeks to create a modelling platform where the influence of predicted future climate scenarios can be tested on a variety of landscape evolutionary processes at a range of spatio-temporal scales. The current DESC modelling platform is based on the Cellular Automaton Evolutionary Slope And River (CAESAR) model, which can simulate morphological changes in river catchments or reaches, on a flood by flood basis over periods of an hour up to several thousands of years. Through the coupling of the quasi three dimensional groundwater model ZOOMQ3D to CAESAR it was shown that although the cumulative sediment output at the base of a catchment is similar to a non-groundwater simulation, the spatio-temporal distribution of erosion and deposition throughout the modelled area was modified, being influenced through the interplay of rainfall events and groundwater maxima and minima. The coupled model is however, computationally expensive and labour intensive; therefore the groundwater model is currently being replaced by simple subsurface flow algorithms. To further improve hydrological representation and increase the number of novel applications, modification of the surface routing algorithms and inclusion of soil characteristics, evapotranspiration and land use are being undertaken, with dynamic vegetation and improvements to landslide development being added in the near future. When complete, the model will be used to simulate the effects of different climate scenarios on a variety of environments.
In the UK, much of the coastal observation, modelling and risk-mitigation work to date has focussed on relatively local domains. CARE, the dynamic coastal evolution project, aims to generate an OpenMI-compliant modelling system that integrates geology, geomorphology and climate, and is focussed on longer time and larger length scales in order to understand better the geomorphological effects of steadily evolving climate regimes. Although this project is in its initial stages, a loose model framework has been created which provides a flexible quasi three-dimensional environment where coastal sediment transport algorithms can be evaluated for a particular study area. Although the framework uses a simple PDF to drive wave climates, in the future running simulations with observed or perturbed wave climate data will open up a number of possible paths including: hind-casting, storm influences, and possible future coastal scenarios.
