Can runoff event types explain some scatter in nitrate C-Q relationships?

Nitrate contamination of rivers from agricultural sources, is a challenging problem for water quality management. The relationship between solute concentrations and streamflow rates (C-Q) observed at catchment outlets provide useful information on hydrolog ...

Synthesizing the impacts of baseflow contribution on concentration-discharge (C-Q) relationships across Australia using a Bayesian hierarchical model

Camille Roland Marie Minaudo

Understanding concentration-discharge (C - Q) relationships can inform catchment solute and particulate export processes. Previous studies have shown that the extent to which baseflow contributes to streamflow can affect C-Q relationships in some catchment ...

Hydrological trends for three headwater catchments in the Alptal valley, Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

Hydrological research in the Alptal valley in central Switzerland started in the late 1960s and has mainly focused on the runoff mechanisms that lead to the very quick runoff response, the relation between forest management and floods, biogeochemistry and ...

Untersuchung der ökomorphologischen Wirksamkeit von Sedimentzugaben unterhalb von Talsperren [Assessment of the eco-morphological effectiveness of sediment augmentation downstream of dams]

Giovanni De Cesare, Christian Mörtl

The regulation of discharge and the retention of sediments in reservoirs disturb the natural water dynamics in residual flow stretches below reservoirs. However, a dynamic river morphology as well as near-natural hydrological hydrographs are fundamen ...

Simulation of long-term spatiotemporal variations in regional-scale groundwater recharge: contributions of a water budget approach in cold and humid climates

Emmanuel Qays Dubois

Groundwater recharge (GWR) is a strategic hydrologic variable, and its estimate is necessary to implement sustainable groundwater management. This is especially true in a global warming context that highly impacts key winter conditions in cold and humid cl ...

The impact of hydrograph variability and frequency on sediment transport dynamics in a gravel-bed flume

Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

A laboratory study was undertaken to investigate how changes in flow regime and hydrograph shape (number of cycled hydrographs and duration of each hydrograph) together impact bedload transport and resulting bed morphology. Three hydrologic conditions (exp ...

GRUN: an observation-based global gridded runoff dataset from 1902 to 2014

Gionata Ghiggi, Vincent Humphrey

Freshwater resources are of high societal relevance, and understanding their past variability is vital to water management in the context of ongoing climate change. This study introduces a global gridded monthly reconstruction of runoff covering the period ...

Hydraulic-morphological habitat assessment in rivers considering residual flow, sediment replenishment and artificial flood events

Severin Stähly

Dams store water and trap sediment in their reservoirs. Downstream river segments, hence, are affected by a limited sediment dynamics. This becomes obvious by river bed incision, limited geomorphological variability and depletion of hydraulic habitats for ...

Hydraulic Reconstruction of the 1818 Gietro Glacial Lake Outburst Flood

Christophe Ancey, Tomás Alfredo Trewhela Palacios, Eric Bardou, Martin Funk

In the spring of 1818, ice avalanches from the Gietro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25x10(6) m(3). Cantonal authorit ...

Modelling the potential of Natural Flood Management practices in an upland peatland catchment with the distributed TOPMODEL

Hélène Amélie Madeleine Boisgontier

In order to reduce flood risk, there is a growing interest in more nature-based solutions, such as Natural Flood Management (NFM), rather than hard-engineering ones. To help build the evidence towards these solutions, we analysed the influence of different ...
