Soil hydraulic data from laboratory rainfall simulation experiments to induce subsurface lateral subsurface flow in 2D soil monoliths

The dataset contains results of laboratory experiments to induce subsurface lateral subsurface flow in 2D soil monoliths taken from a horizon boundary of hummocky ground moraine in Dedelow (north Brandenburg, Germany). Four soil monoliths were sampled along a Btg-CBkg horizon boundary of an Eroded Haplic Luvisol (monoliths: e_ha_LV_1, e_ha_LV_2) and a CBkg-sand lense boundary of a Haplic Regosol (monoliths: ha_RG_3, ha_RG_4). The monoliths were placed under a rainfall simulator in the laboratory and 12 tensiometers and 6 FDR-sensors to measure soil matric potential and soil water content were installed in the upper and lower horizon. Vertical flow through the monoliths and lateral flow along the horizon boundary was measured via a bottom and a side suction disc. The experimental procedure is described in detail in the technical note by Ehrhardt et al. (2022). The dataset includes for each monolith a detailed protocol of applied rainfall rates and pressured heads at the side and bottom suctions discs. For each measurement period (data was subdivided in up to four periods due to large data size)of the monoliths data of the tensiometers and FDR-sensors (calibrated and uncalibrated) as well as calibration data for these sensors are included. Also, the location of the sensors and horizon boundary and the amount of water drained from the side and the bottom of the monolith is given. Two commented R-Scripts give examples on how to plot and interpret the data given for each monolith.
