Over the past fifty years, much of the European landscape has been transformed as a result of changes in land use and management. The growth in intensive agriculture and associated farming practices have changed natural hydrological functioning at the field/hillslope scale, and as a consequence, flood generation mechanisms at the catchment scale may have been affected. In the UK, there is evidence that soil compaction/degradation has created local scale flooding problems, but it is not clear how flood generation at larger catchment scales may have been affected. A wide range of interventions associated with farming and land use management (e.g. land drainage etc) complicate the overall picture. Similar problems have been observed ad documented in other European countries, and there is the added concern about how the catchments will respond to the more extreme rainfall regimes expected under climate change.
The aim of the Session will be to review the current state of knowledge concerning the impacts of land use and management on flood generation, to assess current modelling and predictive capacity, and to identify gaps in knowledge. Current knowledge and understanding is dispersed widely among the agricultural, soils and hydrological research communities, and one of the objectives of the Session will be to bring together scientists from these communities to obtain a comprehensive overview of the current knowledge base. Contributions are invited on small scale agricultural experiments at the field scale which focus on the impacts of land use management practices on runoff generation; on experiments designed to assess the effectiveness of measures taken to control runoff at source; on catchment experiments designed to understand the propagation of impacts to larger scales; on the modelling of runoff generation and impact propagation across scales, and on decision support and policy-making relating to land use management as it affects flood generation and flood risk.
