EP52C:
Advancing Theory and Modeling of River Systems I eLightning


Submit an Abstract to this Session


Session ID#: 62802

Session Description:
A fundamental contribution of earth scientists is to make convincing predictions about river channel change that are useful to the public and to decision makers. This is particularly important in developing areas of the world, where human impact has not yet radically altered river morphologies, but where development pressures are mounting. It is also critical in the face of climate change, and the probable increase in extreme events.  Unnatural channel change contributes to degradation in aquatic habitats, extinction of riverine species, loss of flood-retaining areas etc. The purpose of this session is to communicate recent advances in theory and modelling of how river systems change at all scales and consequently, to identify complex self-organized models of river systems. We welcome studies conducted in different geographical areas, using a broad range of methodologies. Please note that this session is organised by a working group of the International Geomorphological Union.
