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 ...

Applicability 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 ...

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 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 ...

The influence of climate on water chemistry states and dynamics in rivers across Australia

Camille Roland Marie Minaudo

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 ...

Spatio-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 ...

Stream Solutes and Particulates Export Regimes: A New Framework to Optimize Their Monitoring

Camille Roland Marie Minaudo

The quantification of solute and sediment export from drainage basins is challenging. A large proportion of annual or decadal loads of most constituents is exported during relatively short periods of time, a “hot moment,” which vary between constituents an ...

Spatiotemporal Drivers of CO2 Dynamics and Evasion Fluxes from Mountain Streams

Asa Lovisa Viktoria Horgby

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 ...

Photocatalytic performance of TiO2 impregnated polyester for the degradation of Reactive Green 12: Implications of the surface pretreatment and the microstructure

Sami Rtimi

In the present work, we investigate the degradation of recalcitrant industrial textile dye (Reactive green 12) in aqueous solution by TiO2 impregnated polyester at room temperature. The TiO2 loading on polyester was optimized using different polyester pret ...

Fine sediment routing in a cascade of alpine reservoirs: Influence of the inlet angle on settling of fine sediments

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

Reservoir sedimentation is, at present, one of the main concerns in the operational management of dams. The resulting reduction of storage capacity has negative impacts on the hydropower production, flood protection, and availability of water for irrigatio ...

Continuous Long-Term Observation of Suspended Sediment Transport between Two Pumped-Storage Reservoirs

Anton Schleiss, Giovanni De Cesare, Michael Müller

Transport of suspended sediment between the two reservoirs of a pumped-storage plant in Switzerland was monitored over an 8-month period. A turbidity probe was installed on the upstream end of the pressure shaft, in which real-time monitoring was ensured b ...

Sediment contamination assessment in urban areas based on total suspended solids

David Andrew Barry, Luca Rossi, Jonas Margot, Nathalie Chèvre Rossi, Romuald Curdy

Sediment represents an important compartment in surface waters. It constitutes a habitat or spawning site for many organisms and is an essential trophic resource for higher level organisms. It can be impacted by anthropogenic activities, particularly throu ...

Nanostructured Catalysts for the Continuous Reduction of Nitrates and Bromates in Water

Lioubov Kiwi

Nanostructured C-based catalysts have been developed to be used in continuously operated (open-flow) reactors for the removal of bromates and nitrates from polluted water. The catalysts contain transition-metal (Pd, Cu, and Sn) nanoparticles (NPs) supporte ...

Parsimonious hydrological modelling in urban areas: Towards integrated modelling

David Andrew Barry, Luca Rossi, Sylvain Coutu, Dario Del Giudice

Most popular urban hydrological model used in research and engineering (e.g. MOUSE, SWMM, MUSIC,P8) are spatially distributed with linknode drainage network. If some of them (e.g. PURPS, RUNQUAL, SLAMM, StormTac and WBM) treat the catchment in a lumped fas ...
