HYDROLOGICAL FLOW PATHS OF NUTRIENTS IN A SMALL AGRICULTURAL CATCHMENT

Using stable isotope tracers to assess hydrological flow paths, residence times and landscape influences in a nested mesoscale catchment

δ18O measurements in precipitation and stream waters were used to investigate hydrological flow paths and residence times at nested spatial scales in the mesoscale (233 km2) River Feugh catchment in the northeast of Scotland over the 2001–2002 hydrological year. Precipitation δ18O exhibited strong seasonal variation, which although significantly damped within the catchment, was reflected in str...

Catchment hydrological functioning in a Mediterranean context

This study explores how catchment heterogeneity and variability can be summarized in simplified models, representing the dominant hydrological processes. It focuses on Mediterranean catchments, characterized by heterogeneous geology, pedology, and land use, as well as steep topography and a rainfall regime in which summer 5 droughts contrast with high-rainfall periods in autumn. The Ardèche cat...

Predication of sediment delivery ratio in a small agricultural watershed

Multiscale investigations in a mesoscale catchment – hydrological modelling in the Gera catchment

The application of the hydrological processoriented model J2000 (J2K) is part of a cooperation project between the Thuringian Environmental Agency (Thüringer Landesanstalt für Umwelt und Geologie – TLUG) and the Department of Geoinformatics of the Friedrich-SchillerUniversity Jena focussing on the implementation of the EU water framework directive (WFD). In the first project phase J2K was param...

Temporal variability of nitrate transport through hydrological response during flood events within a large agricultural catchment in south-west France.

The temporal variability of nitrate transport was monitored continuously in a large agricultural catchment, the 1110km(2) Save catchment in south-west France, from January 2007 to June 2009. The overall aim was to analyse the temporal transport of nitrate through hydrological response during flood events in the catchment. Nitrate loads and hysteresis were also analysed and the relationships bet...
