Kurzbeschreibung (Abstract)
The Gersprenz basin is ca. 485 km² large and it is located in the federal state of Hesse, Germany. It is part of the river basin district Rhine. River Gersprenz originates in the low mountain range area Odenwald in the southern part of the basin and discharges into the river Main at Stockstadt / Main (topography changes from ca. 600m asl to 100 m asl from south to north). Several larger and smaller tributary streams, e.g. Semme, Lache, Fischbach and Wembach, flow into river Gersprenz, which is ca. 62 km long. Nearly 50% of the basin is used for agriculture, incl. grassland, vineyards and orchards. Forestareas cover ca. 36% and several larger and smaller settlements (ca. 13%) are distributed in the basin. 17 wastewater treatment plants are located in the basin. The state of Hesse monitors water level and discharge data at both Gersprenz gauges Harreshausen (since 1955) and Wersau (since 2006). For assessing water quality, there are further hydrochemical and biological measuring points operated by the state of Hesse. Additionally, periodic, random water sampling is carried out usually on a monthly basis. Since 2016, ihwb measures relevant parameters, which complement the official data of Hesse and literature data. The measurement concept is two-parted, which contains a continuous monitoring at few selected locations and a short-term monitoring with less temporal resolution but higher spatial resolution. Continuous measurements are conducted at relevant points in the basin. Therefore, ihwb installed sensors for measuring water level, water temperature and electrical conductivity at the gauges Harreshausen, Wersau and Groß-Bieberau2. To obtain additional spatial information, a weekly measuring campaign at 12 measuring points in the tributary stream Fischbach is conducted. Here, water depth and flow velocity (since October 2016) as well as electrical conductivity (since February 2017) are measured. In this study, the first data series are analysed to study the spatial and temporal variability in the water courses and the influence of land use in the basin. The results show that electrical conductivity is in relationship with rainfall events and streamflow. Furthermore, land use, such as agriculture, urban areas and waste water treatment plants, change water quality.
