High flow events often comprise the majority of annual discharge and riverine geochemical flux of phosphorus (P) and metals such as iron (Fe) and manganese (Mn) due to glacial melt, snowmelt, and storm-driven sustained high flow. Aquatic ecosystem productivity in receiving water bodies such as Lake Champlain and the Gulf of Alaska (GoA) are impacted by the riverine import of nutrients. The magn...

The objective of this paper is to assess the performance of methods that predict low flows and flood runoff in ungauged catchments. The aim is to learn from the similarities and differences between catchments in different places, and to interpret the differences in performance in terms of the underlying climate-landscape controls. The assessment is performed at two levels. The Level 1 assessmen...

accurate estimate of flood flows at selected return periods is a fundamental step in flood control and design of hydraulic structures. due to the inadequacy or unavailability of flood flow records in several western catchments of iran, traditional regional flood frequency methods lead to remarkable estimate errors, particularly for long return periods. in this research, discriminant analysis is...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

The arid zone catchments of the Lake Eyre Basin (LEB, area of 1.2*10km) in central Australia have unregulated, highly variable flow regimes and contain a paucity of gauging stations. In developing hydrological models of these catchments, only limited gauging station data are available for identifying the broad landscape differences influencing runoff and streamflow. The catchments have been div...
