Description :
This paper uses numerical simulation of flood inundation based on a coupled one-dimensional-two-dimensional treatment to explore the impacts upon flood extent of both long-term climate changes, predicted to the 2050s and 2080s, and short-term river channel changes in response to sediment delivery, for a temperate upland gravel-bed river. Results show that 16 months of measured in-channel sedimentation in an upland gravel-bed river cause about half of the increase in inundation extent that was simulated to arise from climate change. The test site is based upon a 6 km upper reach of the River Wharfe, UK.
