This symposium emphasizes measurement and simulation-based estimates of soil hydrological processes for prediction of space-time patterns in a landscape or watershed context. Studies addressing transport and storage of water and associated chemicals and sediment are welcome. Treatment of soil as a non-static, living medium is encouraged. Soil change and soil climatology focusing on water, vegetation, and land management as the change agents are particularly relevant topics. Integration of ground-based and remotely sensed data into conceptual and process models along with spatial statistical analyses will be presented. Various methods may be used to improve understanding of process interactions and estimation of soil and water variables in space and time.
