Description :
A model to simulate channel changes in ephemeral river channels and to test the effects of hydrological changes due to climate change and/or land use change was developed under the auspices of the EU funded MEDALUS programme (Mediterranean Desertification and Land Use). The model, CHANGISM (Channel Change GIS Simulation Model), is designed to simulate the effect of channel flow events and of climate conditions on morphology, sediment and vegetation, through sequences of events and conditions, over periods of up to several decades. The modelling is based on cellular automata but with calculations for water and sediment continuity. the initial tests of the model are demonstrated and some validation results are presented.
