TL;DR: In this paper, the utility of river flow data is maximised by using tree ring analysis in hydrometry, which is based on tree rings and tree rings are extracted from river flows.

TL;DR: A technique for determining a set of gauging stations which constitutes a homogeneous group for regional flood frequency analysis is presented in this paper, which is based upon the correlation structure of the annual flow values, evaluated through a Monte Carlo simulation study using data from rivers in southern Manitoba.
TL;DR: In this article, a multi-technical approach using classical hydrometry, natural and artificial tracers and electrical resistivity tomography (ERT) was applied to two adjacent steep hillslopes in the Black Forest Mountains, Germany.
Abstract: Hillslope processes (i.e. water flow pathways, source areas and residence times) are essential for predicting water quantities and water quality. A multi-technical approach using classical hydrometry, natural and artificial tracers and electrical resistivity tomography (ERT) was applied to two adjacent steep hillslopes in the Black Forest Mountains, Germany. The differences in the hydrological and hydrochemical responses during three floods were larger than expected based on previously available information of topography, land use and geology. At one site a very dynamic shallow groundwater system dominated the flood generation, which could not be observed at the other site. The reasons for the heterogeneity of hillslope processes are the different soils and structures of the periglacial drift (first-order control); this is augmented by the different land use (pasture vs forest) and its effects on the near-surface processes (second-order control). The multi-technical approach proved very useful: t...
