Abstract The exchange of water and solutes between the stream groundwater along a network affects source composition discharge solute load in stream. To date, this hydrologic turnover has only been analyzed with respect to water. In study, we extend concept analyze effects different conditions on spatial patterns magnitude fluxes. Based coupled stream‐groundwater model built MODFLOW using Streamflow‐routing package, simulated 30 km length evaluated evolution under precipitation streamflow...
Recent discussions in many scientific disciplines stress the necessity of “FAIR” data. FAIR data, however, does not necessarily include information on data trustworthiness, where trustworthiness comprises reliability, validity and provenience/provenance. This opens up risk misinterpreting even though all criteria are fulfilled. Especially applications such as secondary processing, blending, joint interpretation or visualization efforts affected. paper intends to start a discussion community...
Abstract. Lake stratification controls the cycling of dissolved matter within water body. This is particular interest in case meromictic lakes, where permanent density deep limits vertical transport, and a chemically different (reducing) milieu can be established. As consequence, geochemical setting mixing regime lake stabilize each other mutually. We attempt quantitative approach to contribution chemical reactions sustaining stratification. an example, we chose prominent iron meromixis...
Abstract The transition zones between rivers and adjacent riparian aquifers are locations of high biogeochemical activities that contribute to a removal potentially hazardous substances in the aquatic system. potential processes depends highly on subsurface water travel times, which can be determined by using propagation electrical conductivity (EC) signal from river into aquifer. Although this method has been applied verified many studies, we observe possible limitations for usage EC...
Abstract Heavy Precipitation Events (HPE) are the result of enormous quantities water vapor being transported to a limited area. HPE rainfall rates and volumes cannot be fully stored on below land surface, often leading floods with short forecast lead times that may cause damage humans, properties, infrastructure. Toward an improved scientific understanding entire process chain from formation flooding at catchment scale, we propose elaborated event-triggered observation concept. It combines...
Abstract Planning an event-based monitoring campaign on the regional scale is challenging, e.g. timing and location of visits can dramatically impact efficacy depends optimal environmental conditions required by measurement parameters overarching goal. Therefore we developed a generic planning approach utilizing interactive visualization methods implemented this into component-based web tool called Tocap: Tool for Campaign Planning. As case study, determine most suitable time event-driven,...
