Abstract
In many cases, water-quality models have a poor basis of calibration and validation due to inadequate or sparse input data. Water-quality monitoring is often limited to a few sites within the stream network where samples are collected and analyzed at some intermittent frequency (e. g. monthly). In particular, this limited temporal sample coverage causes problems in modelling water-quality variables such as phosphorous that are mainly transported during short-term events.In order to address this problem, a meso-scale catchment was equipped with a measurement network for obtaining spatially and temporally higher-resolution data of water quality, meteorological data, and soil moisture data. The selected test site is the upper catchment of the Gera River (approx. 850 km²). This catchment features different landscape forms that are typical of regions in the lower mountain range in Central Europe. Measurements started in summer 2008.The goal of the data collection is to establish a database for the improvement and development of eco-hydrological models like the JAMS/J2000-S.
