Summary

Under temperate climatic conditions, water is an important control for ecosystem functioning. Water availability and fluxes control plant productivity, root uptake of nutrients, and element leaching to the groundwater. Water cycles in soil may vary much in space and time. Modeling the water budget by determining precipitation (P), evapotranspiration (ET), change in soil water storage (?S), and exchange with groundwater (?Gw) with particular consideration of the temporal and spatial variation is therefore a prerequisite for setting up element budgets.

The objective of this proposal is to model the water budget of grassland by continuous measurements at selected points (P, ET, ?S, and ?Gw). In addition to this, spatial variation of the soil water cycle and its relation to soil hydrological properties and vegetation cover will be assessed using geostatistical methods.
