Comparison of sampling strategies for solute load estimates

Description: Das Projekt "Comparison of sampling strategies for solute load estimates" wird vom Umweltbundesamt gefördert und von Universität Zürich, Geographisches Institut durchgeführt. To assess the status and actual trends of surface water bodies as proposed by the EU water framework directive, reliable monitoring strategies are fundamental. However, in research and governmental water quality monitoring studies, clear guidelines for experimental design of monitoring campaigns are often unavailable, leading to flawed or ambiguous data sets. Not only are the data difficult to interpret, but incorrect conclusions and resulting policy recommendations can have far-reaching implications. Inadequate sampling devices or strategies are often responsible for sampling artifacts. These artifacts can obscure real variations in the environment. This is especially critical when considering nutrients, pollutants or environmental tracers, which vary with discharge fluctuations. In this project we compare sampling strategies, methods, and new devices using case studies from research catchments in Switzerland and Germany and an international watershed (Lake Constance). We evaluate time, water level and volume proportional integrative sampling strategies active with grab sampling for solute load estimates with emphasis on nutrient fluxes during pronounced discharge events. We compare various active samplers (event-triggered sampling, time-proportional composite sampling, volume-proportional composite sampling) with passive samplers for several events in different catchments.
