Reduction of riverbed clogging related to sediment flushing
Giovanni De Cesare, Romain Maxime Dubuis
The ecological effects of dams on sediment and river flow have been subject to an increasing attention, leading to the implementation of mitigation measures such as environmental flow release and sediment replenishment. However, fine sediment dynamics have ...
CRC Press/Balkema2023Applicability of the landscape evolution model in the absence of rills
David Andrew Barry, Andrea Rinaldo, Paolo Perona, Seifeddine Jomaa, Mohsen Cheraghi, Andrea Cimatoribus
Despite numerous applications of physically-based models for incised landscapes, their applicability for overland flow on unchanneled surfaces is not known. This work challenges a widely used landscape evolution model for the case of non-uniform rainfall a ...
2022Synthesizing 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 ...
COPERNICUS GESELLSCHAFT MBH2022The Land-Water-Energy Nexus of Ruzizi River Dams (Lake Kivu Outflow, African Great Lakes Region): Status, Challenges, and Perspectives
Hydroelectric power (HP) represents the main source of electricity in Africa, including the Democratic Republic of Congo. The demand for new dam construction is high, and major projects are currently progressing through planning and implementation stages. ...
FRONTIERS MEDIA SA2022Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland
Jana Freiin von Freyberg, Ilja van Meerveld
When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...
2021The influence of climate on water chemistry states and dynamics in rivers across Australia
For effective water quality management and policy development, spatial variability in the mean concentrations and dynamics of riverine water quality needs to be understood. Using water chemistry (calcium, electrical conductivity, nitrate-nitrite, soluble r ...
WILEY2021More green and less blue water in the Alps during warmer summers
Gabriele Manoli, Peter Molnar, Paolo Burlando
Climate change can reduce surface-water supply by enhancing evapotranspiration in forested mountains, especially during heatwaves. We investigate this ‘drought paradox’ for the European Alps using a 1,212-station database and hyper-resolution ecohydrologic ...
2020Spatio-Temporal Relationship between Land Cover and Land Surface Temperature in Urban Areas: A Case Study in Geneva and Paris
Roberto Castello, Jean-Louis Scartezzini, Dasaraden Mauree, Xu Ge
Currently, more than half of the world’s population lives in cities, which leads to major changes in land use and land surface temperature (LST). The associated urban heat island (UHI) effects have multiple impacts on energy consumption and human health. A ...
2020Spatiotemporal Drivers of CO2 Dynamics and Evasion Fluxes from Mountain Streams
Inland waters are key components of the global carbon cycle, emitting a substantial amount of carbon dioxide (CO2) to the atmosphere. Climate change and global warming affect mountain catchments significantly, leading to glacier retreat and changing precip ...
EPFL2019Sediment flushing downstream dams: a study on the clogging by fine sediments
Giovanni De Cesare, Christophe Ancey, Romain Maxime Dubuis
Water reservoirs used to produce electricity have an impact on the environment and durability by : • stopping the natural sediment flux • changing the flow regime downstream of the reservoirs • storing (fine) sediments that reduce the storage volume Those ...
