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

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 ...

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

Jana Freiin von Freyberg

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 ...

Wind turbine wakes on escarpments: A wind-tunnel study

Fernando Porté Agel, Arslan Salim Dar

In this study, the wake behind a wind turbine located on an escarpment is investigated using particle-image velocimetry in a wind tunnel. Five different escarpment models are used, which vary in the windward side shape from forward facing steps (FFS) with ...

Examination of the seepage face boundary condition in subsurface and coupled surface/subsurface hydrological models

Damiano Pasetto

A seepage face is a nonlinear dynamic boundary that strongly affects pressure head distributions, water table fluctuations, and flow patterns. Its handling in hydrological models, especially under complex conditions such as heterogeneity and coupled surfac ...

Hydrological Processes in a High Alpine Watershed

Raphaël Mutzner

Alpine hydrology is particularly challenging due to the complexity of mountainous terrain and the spatial and temporal variability of meteorological parameters such as precipitation, temperature and evaporation. Yet improving our understanding of hydrologi ...

Understanding the relative role of hillslope processes and geomorphology in Alpine catchments

Bettina Schaefli, Francesco Comola

Hydrologic prediction in small Alpine catchments (up 50-200km2) plays a crucial role for water and flood man- agement in downstream areas. In this generally steep environments, understanding the relative role of hydrologic processes in the hillslopes and o ...

Similarity Analysis between near surface soil moisture and streamflow during recession events in an alpine catchment

Andrea Rinaldo, Marc Parlange, Steven Vincent Weijs, Raphaël Mutzner

Spatial and temporal variability of near surface soil moisture is important for understanding streamflow generation in high altitude mountain catchments since antecedent soil moisture plays an important role in the timing of runoff. For relatively small to ...

Snow cover runoff and stream discharge modelling during snow melt in Alpine terrain

Michael Lehning, Nander Wever, Mathias Thierry Pierre Bavay, Charles Fierz

The understanding of the role of snow cover runoff in complex terrain for the hydrological cycle is still limited. Water flow in snow is a complex process, because the strong layering of the snow cover causes strong vertical variation in hydraulic properti ...

Influence of natural attenuation and river fluctuations on benzene dispersion in an alluvial aquifer subject to strong interactions with surface water

Jordi Batlle-Aguilar

A contaminated alluvial aquifer, in a former gasworks factory and discharging to an adjacent river, was the object of field and laboratory investigations to assess pollutant attenuation and dispersion. Various organic and inorganic compounds were found in ...

Hydrologic and biogeochemical controls of river subsurface solutes under agriculturally enhanced ground water flow

Janet Gordon Hering

The relative influences of hydrologic processes and biogeochemistry on the transport and retention of minor solutes were compared in the riverbed of the lower Merced River (California, USA). The subsurface of this reach receives ground water discharge and ...
