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

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 ...

The Hydro-Morphological Index of Diversity: a planning tool for river restoration projects

Walter Gostner

Flood protection and river engineering projects nowadays have to improve also the ecological condition of the river. Very often the space is not available for a full restoration of the river morphology. Therefore the hydro-morphological heterogeneity has t ...

Riprap Protection of Vertical-Wall and Spill-Through Bridge Abutments

Anton Schleiss, António Heleno Cardoso

Scour around bridge abutments frequently leads to the collapse of bridge superstructures. Consequently, scour countermeasures are usually designed and installed by river engineers, riprap matting being the most widespread solution. The associated design cr ...

Has the Three-Gorges Dam made the Poyang Lake wetlands wetter and drier?

David Andrew Barry

The Three-Georges Dam holds many records in the history of engineering. While the dam has produced benefits in terms of flood control, hydropower generation and increased navigation capacity of the Yangtze River, serious questions have been raised concerni ...

Physical and numerical model study investigating plunge pool scour at Kariba Dam

Anton Schleiss, Michael Pfister, Erik Bollaert, Rafael Xavier Meriade Duarte

Kariba Dam is a 128 m high arch dam located on the border between Zambia and Zimbabwe. The dam has been constructed in the late 1950s and formed at that time the largest man-made lake worldwide. The dam is equipped with 6 flood gates, each about 9 m high b ...

Multi-modal change detection, application to the detection of flooded areas: outcome of the 2009-2010 data fusion contest

Devis Tuia

The 2009-2010 Data Fusion Contest organized by the Data Fusion Technical Committee of the IEEE Geoscience and Remote Sensing Society was focused on the detection of flooded areas using multi-temporal and multi-modal images. Both high spatial resolution opt ...

Failure risk analysis of riverbank ripraps with Monte Carlo simulation

Anton Schleiss, Michael Pfister, Mona Jafarnejad Chaghooshi

The potential failure evaluation of river embankment structures such as ripraps, resulting from erosion or over-flows during flood events, is the main issue of their stability and safety assessment. Moreover, a changed sediment transport in rivers as a pos ...

Stress partitioning for bedload transport in rivers with immobile boulders

Anton Schleiss, Tamara Ghilardi

When applied to mountain torrents, sediment transport formulae habitually overestimate the bedload by several orders of magnitude, even if they have been developed for steep slopes. The reason is that the influence of macro-roughness elements, such as larg ...

Hydromorphological implications of local tributary widening for river rehabilitation

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy

The hydromorphological implications of the local widening of a tributary where it enters a confluence were investigated in a laboratory setting that is representative of the 20 major confluences on the channelized Upper Rhone River. Although local tributar ...
