Technical note: Two-component electrical-conductivity-based hydrograph separation employing an exponential mixing model (EXPECT) provides reliable high-temporal-resolution young water fraction estimates in three small Swiss catchments

The young water fraction represents the portion of water molecules in a stream that have entered the catchment relatively recently, typically within 2-3 months. It can be reliably estimated in spatially heterogeneous and nonstationary catchments from the a ...

Sediment continuity and augmentation measures

Giovanni De Cesare, Robin Schroff

Impaired sediment transport can have numerous adverse impacts on the eco-morphodynamics of the riverscape. If well designed, sediment augmentation measures present a promising mitigation approach at different scales. This chapter focuses on flume experim ...

Exploring the efficacy of reservoir fine sediment management measures through numerical simulations

Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet, Montana Marshall

Reservoir sedimentation is one of the main challenges in the sustainable operation of large reservoirs because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. To ensure the sustainability of deep reservoir ...

Colloidal transport and deposition through dense vegetation

David Andrew Barry, Li Chen, Congrong Yu

The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...

Impact of Escherichia colifrom stormwater drainage on recreational water quality: an integrated monitoring and modelling of urban catchment, pipes and lake

Frédéric Charles Soulignac

In recent years, recreational waterbodies are increasingly favoured in urban areas. In spite of the growing concerns for maintaining the required bathing water quality, the impacts of stormwater drainage are still poorly controlled. In this context, this s ...

Quantification and characterization of microplastics input from runoff water in Kamo and Takano Rivers, Kyoto, Japan.

Microplastic particles can be found everywhere in the world and sources, transport processes and impact on the environment and human health is yet to be well understood. The goal of this work is to quantify and characterize the impact of non-point source m ...

Control of sediment transport on an alpine catchment basin for the safe application of smart storage operations on an run-off-river HPP

Pedro Filipe De Almeida Manso, Jessica Zordan, Rafael Casimiro De Figueiredo

Smart storage operations (SSO) have been implemented on an alpine run-off-river HPP (case study: KW Gletsch-Oberwald HPP) in order to enhance the flexibility of the power plant (ref poster SmallFlex). SSO operations consist on the use of available space un ...

Rejuvenation of Lakes in Indian Cities: A Case Study for the Betterment of Wetlands in Bangalore

Pollution is defined as “to make something impure”. Water bodies, natural or man-made, are susceptible to pollution ranging from plastic waste disposals to urban and industrial sewage discharge. Until 1960, records show that there were 262 water bodies in ...

Role of microbial cell properties on bacterial pathogen and coliphage removal in biochar-modified stormwater biofilters

Stormwater biofilters are distributed stormwater control measures for managing urban runoff. Recent work has shown that adding biochar to biofilters can reduce stormwater contaminant concentrations, including fecal indicator bacteria (FIB). However, the po ...

Swiss Rainfall Mass Curves and their Influence on Extreme Flood Simulation

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme flood estimates for dam safety are routinely obtained from hydrologic simulations driven by selected design storms. The temporal structure of such design storms can be obtained from Rainfall Mass Curves (RMCs), which are adimensionalized curves of ...
