HoBo - Function of the soil in the water balance - Soil physics and soil hydrology
Abstract
In this AP, it will be clarified how different mechanical stress with different harvesting technologies as well as biological remediation measures affect physical properties of the soils (pore volume, pore continuity, hydraulic conductivity, usable water storage capacity) in the short and medium term compared to unstressed areas. The effects on components of the water balance (infiltration versus surface runoff, water storage and water availability) are empirically investigated at different scale levels (sprinkling experiments, continuous and discontinuous soil moisture measurements) and extrapolated with hydrological models to the slope scale or small catchment level. Answering the question 'How much water remains in the system under different weather conditions and is this water available for the remaining stand or regeneration?' is of great importance for the sustainability of forest management in view of rapidly changing climatic conditions in the study area (drier overall, shift in precipitation intensity - more heavy precipitation, longer dry periods). Furthermore, the calibrated hydrological models serve to reconstruct soil conditions at the time of harvesting operations (WP2) and can be used as forecasting tools for future land use planning.
