Effects of changed climatic conditions and water resources management on the water balance of a wet grassland site

The data set contains daily and monthly values of weather data, groundwater levels und water balance components of two groundwater lysimeter of a lysimeter station and a weather station in the Spreewald wetland from 2010 to 2023. The two soil monoliths were extracted on the location of the lysimeter station and represent the site conditions the wetland. The biomass was harvested two time per year. Leaf area index was measured before harvesting the biomass. The biomass was dried and weighted (dry yield). The groundwater levels in the two lysimeters distinguish in their depth below the surface as result of a different water resources management. They represent different water resources management options for wet grassland sites discussed in the region (Dietrich, 2024). One lysimeter represents the conditions of the surrounding area (actual water management option). The other option has higher target water levels in winter and spring. The results show the effects of a modified water management on the water balance components evapotranspiration, inflow, outflow and water storage change, the groundwater hydrograph, the development of the vegetation and the biomass yield.
