CoastClim of Simulator of Climate Change Risks and Adaptation Initiatives (SimClim)

The Simulator of Climate Change Risks and Adaptation Initiatives (SimClim) software enables examination of future climate scenarios in several contexts. The method features a separate consideration for sea-level rise (sea-level generator) due to climate change and global warming and that resulting from local land movements.

One of the distinct advantages of using the generator is that it allows rapid generation of place-based sea-level scenarios, which account for some uncertainties associated with emissions scenario, but may not account for isostatic change. SimClim also includes a set of developed impact models. For the coastal zone, the focus is on erosion and flooding. The simple erosion model is a modified version of the Bruun Rule, which takes into account storm effects, local sea-level trends and lag effects in order to provide time-dependent response of the shoreline to sea-level rise at selected sites. The coastal flood model is spatial and allows the user to examine changes in the areas of potential inundation from the combined effects of sea-level rise and extreme storm events.

The purpose of SimClim is to link and integrate complex arrays of data and models in order to simulate, temporally and spatially, bio-physical impacts and socio-economic effects of climatic variations, including extreme climatic events. In this way, it provides the foundation for assessing options for adapting to the changes and reducing the risks. SimClim is designed to support decision-making and climate proofing in a wide range of situations where climate and climate change pose risk and uncertainty.

Appropriate Use A tool to aid decision-making under changed climate conditions.
Scale SimClim can be applied in sub-national, national, regional and global analysis.
Key Output Current shoreline (m).
Key Input For the coastal erosion model part of SimClim, one requires; shoreline response time, closure distance (m), depth of material exchange (m), dune height (m) and residual movement (m/year) and well as storm parameters.
Ease of Use The distinctive advantage of the SimClim open system, as opposed to the hard-wired system, is the flexibility afforded to users for importing their own data and models in order to customise the system for their own purposes – much like a GIS.
