A complex hydrologic-hydraulic model has been developed for the Upper Rhone River basin in Switzerland. It is currently operational in the Canton of Valais for real-time flood forecasting and management, providing automatic warnings to the crisis cell of t ...
Flood management is more than ever an issue for dam designers and engineering consulting firms in charge of rehabilitation works. Piano Key Weirs are a new cost-effective type of spillway designed to improve dams discharge capacity. These structures are pa ...
The sediment transport capacity of the Avançon river through the city of Bex in Switzerland is limited. During the October 2000 flood event, water levels rose to danger limits. After the flood, the river channel was completely filled with sediments, with a ...
Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity is directly proportional to the crest length several types have been developed with the purpose to increase the length of the latter. Among these types t ...
Free overfall weirs are hydraulically efficient and reliable in operation. With this, the overfall capacity depends on the hydraulically active developed length of the weir. Folded types of weir, such as the piano key weir (PKW), provide an over-proportion ...
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 ...
The simulation of run-off in Alpine catchment areas is essential for the optimal operation of high head storage hydropower plants (HPPs) under normal flow conditions, but also in case of flood events. A conceptual semidistributed numerical approach is pres ...
The use of existing hydroelectricity multi-reservoir systems for flood protection may be an efficient approach in many catchment areas. The assessment of the protection potential offered by the hydropower plants during floods requires a comprehensive analy ...
The mouth of the Baye de Clarens torrent in Switzerland is currently constrained by lateral training walls, sequent sills and a bridge with a low hydraulic capacity. Due to a bed load trap upstream, few sediments reach the mouth. To improve flood protectio ...
Flood protection often calls on to the realization of retention works for bed load as well as wood and debris flow. Certain relatively recent arrangements did not perform according to their intended function, what shows the complexity of the design and the ...
