LSPIV implementation for environmental flow in various laboratory and field cases

Anton Schleiss, Sameh Ahmad Kantoush

Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different ...

Review of degradation and failure phenomena in photovoltaic modules

Sameh Ahmad Kantoush

The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradat ...

Rehabilitation of St-Marc dam: Model studies for the spillways

Sameh Ahmad Kantoush, Marcelo Leite Ribeiro

The Saint-Marc dam, owned by EDF-France is a concrete gravity dam built between 1926 and 1930. It is located near Limoges (France) on the Taurion River and has currently two gated spillways, one 7.50 m wide on the right bank and the other with two passes o ...

Influence of shallow reservoir geometry on the flow pattern and sedimentation process by suspended sediments

Anton Schleiss, Erik Bollaert, Sameh Ahmad Kantoush

Résumé Dans le cadre du projet de recherche sur la sédimentation de réservoirs à faible profondeur, en particulier les sédiments en suspension, les paramètres suivants ont été étudiés: l’influence de la géométrie du réservoir sur le transport des sédiments ...

Experimental study on the influence of the geometry of shallow reservoirs on flow patterns and sedimentation by suspended sediments

Sameh Ahmad Kantoush

The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...

Large-scale PIV surface flow measurements in shallow basins with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Shallow depth flow fields and low velocity magnitudes are often challenges for traditional velocity measuring instruments. As such, new techniques have been developed that provide more reliable velocity measurements under these circumstances. In the presen ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Channel formation during flushing of large shallow reservoirs with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Depositional and flow patterns are first described to gain an understanding of the erosion patterns during hydraulic flushing in a reservoir. Considering the importance of this issue, two modes of flushing operation for control of sedimentation were perfor ...

A Novel Method for River Bank Detection from Landsat Satellite Data: A Case Study in the Vietnamese Mekong Delta

Giovanni De Cesare, Sameh Ahmad Kantoush

River bank (RB) erosion is a global issue aecting livelihoods and properties of millions of people. However, it has not received enough attention in the Vietnamese Mekong Delta (VMD), i.e., the world’s third largest delta, compared to salinity intrusion an ...

Deposition of sediment mixture due to jet effluent into a rectangular shallow reservoir

Anton Schleiss, Sameh Ahmad Kantoush

Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...

Evolution of sediment deposition and flow patterns in a rectangular shallow reservoir under suspended sediment load

Anton Schleiss, Sameh Ahmad Kantoush

The deposition behavior of fine sediment is an important phenomenon, which remains unclear to engineers concerned about reservoir sedimentation. In the present case bed level changes, suspended sediment concentrations, and flow velocities were measured in ...

Experimental and numerical analysis of flow instabilities in rectangular shallow basins

Anton Schleiss, Sameh Ahmad Kantoush

Free surface flows in several shallow rectangular basins have been analyzed experimentally, numerically and theoretically. Different geometries, characterized by different widths and lengths, are considered as well as different hydraulic conditions. First, ...

Flow field investigation in a rectangular shallow reservoir using UVP, LSPIV and numerical modelling

Anton Schleiss, Giovanni De Cesare, Sameh Ahmad Kantoush

Low velocity and shallow-depth flow fields often are a challenge to most velocity measuring instruments. In the framework of a research project on reservoir sedimentation, the influence of the reservoir geometry on sediment transport and deposition was stu ...

Et si les crues de l'Arve rejoignaient le Léman? - Etude de faisabilité de la dérivation des crues de l'Arve pour améliorer le rendement de la centrale du Sujet et décharger la retenue de verbois

Anton Schleiss, Giovanni De Cesare, Sameh Ahmad Kantoush

The Arve River is the most important tributary of the Rhone River The Arve has a very high sediment transport capacity due to its steep slope in the Alpine Valley. These solid materials deposit in the Rhone River. Because of the high sedimentation rate in ...
