Fulfilling Riverscape – a creative interdisciplinary approach

Giovanni De Cesare, Paolo Perona, Sylvie Tram Nguyen

Hydrological, water technological, managerial and human induced processes affect aquatic, amphibian and terrestrial organisms and their habitats, far beyond the main channel of a river. This Riverscape includes diverse riparian habitats which vary in space ...

Ecosystem engineering by periphyton in Alpine proglacial streams

Tom Ian Battin, Davide Mancini, Marc Aguet, Adrijan Selitaj, Matteo Roncoroni

Stream periphytons are candidate ecosystem engineers in proglacial margins. Here, we quantify the extent to which they are engineers for the case of hillslope-fed tributaries in the terrace zones of proglacial margin alluvial plains. Candidate ecosystem en ...

The Land-Water-Energy Nexus of Ruzizi River Dams (Lake Kivu Outflow, African Great Lakes Region): Status, Challenges, and Perspectives

Alfred Johny Wüest

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. ...

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 fundamental ...

Hydrological and hydraulic solutions for the sustainability of habitat life in human altered streams

Amin Niayifar

In this thesis, I aim to contribute to the research towards improving the sustainability of habitat life in streams affected by anthropogenic activities. With the growing trend of altering natural water regimes due to hydropower operations, irrigation, and ...

Prediction of river water temperature: a comparison between a new family of hybrid models and statistical approaches

Aurélien Gallice, Sebastiano Piccolroaz, Marco Toffolon, Elisa Calamita

River water temperature is a key physical variable controlling several chemical, biological and ecological processes. Its reliable prediction is a main issue in many environmental applications, which however is hampered by data scarcity, when using data-de ...

Prolonged river water pollution due to variable-density flow and solute transport in the riverbed

David Andrew Barry

A laboratory experiment and numerical modeling were used to examine effects of density gradients on hyporheic flow and solute transport under the condition of a solute pulse input to a river with regular bed forms. Relatively low-density gradients due to a ...

Morphodynamic differences induced by different confluence angles in widen confluences

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity ...

Influence of dam operation on water resources management under different scenarios in the Zambezi River Basin considering environmental objectives and hydropower

Théodora Cohen Liechti

Worldwide, almost 50,000 dams over 15 m height have been built during the last six decades with an aggregated storage capacity of 6,000 km3. The fact that large dams, by increasing irrigation and hydroelectricity production, can sustain development and red ...

Operation of Complex Hydropower Schemes and its Impact on the Flow Regime in the Downstream River System under Changing Scenarios

Martin Peter Bieri

Hydropower is the world’s most important renewable electricity source. More than 40% of European hydroelectric energy is produced in Alpine countries. High-head storage hydropower plants (HPP) contribute significantly to peak energy production as well as e ...
