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