15. Ecohydrological water flow analysis of a Swedish landscape in a 100 year perspective
Sammanfattning : The study basically involves analysis in a 100 year perspective of the hydrological response on precipitation from different landscape elements in south-central Sweden, characterized by the interaction of topography, soil type, land management and canopy cover.For this purpose, a dynamic water partitioning model, based on the soil moisture balance, was developed together with a Geographical Information System (GIS)-supported method for the detection of the spatial distribution of soil wetness as an indicator of the probability to act as discharge or recharge areas respectively.
