Objective
The influence of temperature change on coastal sediment erosion
The climatic changes predicted by the Intergovernmental Panel on Climate Change (IPCC) "business as usual scenario"estimates a global rate of temperature increase of 0.25°C per annum over the coming decade. This temperature change is likely to have a major impact over all terrestrial and aquatic ecosystems. Of particular importance in terms of human interest are the changes that will be brought about at the interface region between land and sea. It is on the coastal zone that the main brunt of sea-level rise and increasing frequency and force of storm events will be expressed. Here ecosystems must change to keep pace with rising water levels and increase hydrodynamic forcing.
The nature of this change and the way in which systems will respond is difficult to predict but is an important goal for environmental research. The CLIMEROD project encompasses an experimental and modelling approach to assess the likely effects of temperature change on elements of depositional system which control the physical stability and transport of coastal sediments. Physical features such as rheometrical properties effects on transport phenomena and biological changes such as enhanced productivity under increased CO2 will be investigated by an interdisciplinary team comprising hydrodynamics and biological modellers, microbiologists, sedimentologists, rheologists and mathematicians.
The erosion of coastal sediment and the transport of suspended material is a critical factor in the prediction of change to coastal environmental systems. Many modelling studies have attempted to predict the behaviour of sediments yet there are no studies which address the likely scenario in the event of temperature rise with the inherent physical and biological changes that will result. It is clear from recent studies that sediment erosion is mediated by biological factors and that temperature is central parameter not only to the physical dynamics of the system (viscosit density, etc.) but to the rate and nature of biological mediation (e.g. extracellular polymeric structures (EPS) production). The motivation behind CLIMEROD is to analyse the major climatic variables of temperature and CO2 concentration on the erosive properties of sediments and the rheological behaviour of sediment suspension and deposited beds. This information is required to predict the response of depositional systems to global climate change scenarios and the likely-hood of increasing or decreasing net transport under the influence of global warming.
