The impact of upland land management on flooding: insights from a multiscale experimental and modelling programme

摘要: A programme of field experiments at the Pontbren catchment in Wales has, since autumn 2004, been examining effects land use change on flooding. The possesses a long history artificial drainage its clay soils and intensification sheep farming. Increased flood runoff has noted within last decades, as mitigating effect trees scale. To examine local catchment-scale management catchment, including potential advantages planting additional trees, multidimensional physically based model developed conditioned data from an intensely instrumented hillslope. is used to small strip Results demonstrate that careful placement such interventions can reduce magnitudes peaks by 40% challenges associated with upscaling these results Upper Severn catchments are discussed.
