We present an approach for process conceptualization in hillslope hydrology. We develop and implement a series of virtual experiments, whereby the interaction between water flow pathways, source and mixing at the hillslope scale is examined within a virtual experiment framework. We define these virtual experiments as ‘numerical experiments with a model driven by collective field intelligence’. ...

Abstract. Studies engaging in tracking headwater carbon signatures downstream remain sparse, despite their importance for constraining transfer and transformation pathways of organic (OC) developing regional-scale perspectives on mechanisms influencing the balance between remineralization export. Based a 40-month time series, we investigate dependence hydrology seasonality discharge sediment OC...

The theme for the papers in the issue is “Hydrology and the Environment”. There is a mix of review papers and research papers. Climate change and water are very important subjects in these times. Hydrology is the science of water, and the environment has water as one of the three principal earthly components, the other two being the air and the earth. Hence, hydrology and the environment would ...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract We investigated one of the best-known and second largest karst areas in Germany (Blautopf Catchment) that offers a unique access waters of the unsaturated zone through a large cave system. As tracers for water flow and storage we measured ...

The Training Range Environmental Evaluation and Characterization System (TREECSTM) uses average annual hydrologic conditions as inputs for multi-media fate and transport models. This simplification reduces model complexity and data input requirements while providing the capability to conduct long-term predictions of the fate of munitions constituents (MC) as well as other contaminants. TREECSTM...

The long-term efficacy of stormwater treatment systems requires continuous pollutant removal without substantial re-release. Hence, the division of incoming pollutants between temporary and permanent removal pathways is fundamental. This is pertinent to nitrogen, a critical water body pollutant, which on a broad level may be assimilated by plants or microbes and temporarily stored, or transform...
