Stable sulfur (S) isotope ratios can be used to identify the sources of sulfate contributing to streamwater. We collected weekly and high-flow stream samples for S isotopic analysis of sulfate through the entire water year 2003 plus the snowmelt period of 2004. The study area was the 41-ha forested W-9 catchment at Sleepers River Research Watershed, Vermont, a site known to produce sulfate from...

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...

the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...

Of several problems associated with theoretical explanations of the jokul­ hlaups which emerge from the outlet glacier Skeioararj okull of the ice c ap Vatnajokull i n southeast Iceland, the mechanism of flood ini ti atio n i s one that has h itherto defied explanation. We provide such an explanation based on a careful analysis of the classical Nye-Rothlisberger model; near the subglacial lake ...

The problems and present methods for the calculation of monthly and annual effective infiltration coefficients in Dinaric karst catchments which cover areas smaller than 200 km are discussed. An example is given of the catchment of the Gradole karst spring, which covers 114 km. The climate on the catchment is North Mediterranean, with average annual rainfall of 986 mm, average air temperature o...

The development of catchment modelling tools has gained considerable momentum through the Cooperative Research Centre for Catchment Hydrology’s Catchment Modelling Toolkit. This repository of models (see www.toolkit.net.au) allows the modeller to select the most appropriate tools with which to best represent their catchment and associated constituent processes. While this has improved the abili...
