Coastal Modelling Environment (CoastalME) is a computer program, to simulate decade and longer coastal morphological changes. It is free and open-source software, developed originally by a small team at the Environmental Change Institute, Oxford University, United Kingdom, [3] and is now being maintained and extended by an international developer community [4][5].
CoastalME is intended to give scientists an coastal engineers an effective but easily learnable platform for implementing geoscientific methods. This is achieved by the application programming interface (API). CoastalME has a fast-growing set of geoscientific methods, bundled in exchangeable module libraries.
Coastal morphology change is simulated as dynamically linked line and raster objects. The hierarchy of panels illustrate how a real coastal morphology is conceptualized as shoreline, shoreface profiles and estuary elements. All elements can share sediment among them. The shoreface comprises both consolidated and non-consolidated material that forms the cliff, shore platform and beach respectively. At every time step the shoreline is delineated at the intersection of the Sea Level and the ground elevation. Shore face profiles are delineated perpendicular to the shoreline. The Sea Level and wave energy constrains the proportion of shoreface profiles that are morphologically active at each time step. Eroded sediment from the consolidated profile is added to the drift material to advance the shoreline or loss as suspended sediment. Gradients of the littoral drift further controls the advance and retreat of the beach profile and the amount of sediment shared with nearby sections of the shoreline.
