Description
Abstract:
The dataset contains measurment data from a weighable groundwater lysimeter in the Spreewald wetland. Water budget values and water levels were selected for 29 rainfall events > 10 mm between May 2010 and September 2012. The parameters were evaluated for different points of time and periods after and before the rainfall events. Special focus was set on water storage characteristics of the thin unsatureted zone of the shallow water table site. The data shows the effect of different assumptions (equilibrium conditions vs. dynamic conditions) on the estimated exhaustion of the unsaturated zone.
Methods:
The weighable groundwater lysimeter station consits of different measurement systems for the estimation of water budget parameters (DS - storage change = mass change, Rin - inflow, Rout - outflow, P - precipitation, ETa - actual evapotranspiration). The soil monoliths have an area of 1 m² and a height of 2 m. Each monolith is placed on a weighing system consisting of three loading cells (model 3510, Soemer, weighing accuracy 0.1 kg). Each monolith is connected to an own compensation tank via a tube located at the bottom. The water level in the tank was measured by pressure transducers (PR-46X, Keller, resolution of 1 mm). The volumes of the inflow or outflow were calculated from the tank’s water level change, yielding a resolution of 0.035 l. All measured quantities were logged at 10-min intervals (data logger DL-104, UGT), forming the basis to obtain hourly values of the water balance components. The precipitation was estimated on the basis of the mass change and the measured inflow or outflow during the rainfall. It was assumed that no evapotranspiration occurred during this time. The precipitation measurement of a meteorological station provided information on the beginning and the end of rainfall events. The evapotranspiration is calculated on basis of the water budget equation.
