Solution viscosity and flocculation characteristics of linear polymeric flocculants in various media

Rheological characteristics of linear copolymers of acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride (Q9), differing in molar mass and chemical composition, have been studied in distilled water (DW) and industrial water (IW) obtained from a ...

Sediment evacuation from reservoirs through intakes by jet induced flow

Jolanda Maria Isabella Jenzer Althaus

Today’s worldwide yearly mean loss of storage capacity due to sedimentation is already higher than the increase of capacity by the construction of new reservoirs for irrigation, drinking water and hydropower. In Asia for example 80% of the useful storage c ...

Innovative approaches to sediment management

Anton Schleiss, Giovanni De Cesare, Jolanda Maria Isabella Jenzer Althaus

Sedimentation close to dams in large and deep reservoirs is mainly related to sediment transport by turbidity currents. The state of the art regarding the management of turbidity currents is presented here, and illustrated with two case studies. Possible s ...

Experimental Study on Dam-Break Waves for Silted-Up Reservoirs

Anton Schleiss, Rafael Xavier Meriade Duarte

The overall dam-break phenomenon is currently well understood for reservoirs filled with water. However, many dams face serious problems of reservoir sedimentation. Thus, regarding risk management, the influence of a large amount of sediment in the reservo ...

Complémentarité de la modélisation physique et numérique à l’exemple d’un aménagement hydroélectrique / Complementarity of physical and numerical modeling using the example of a run-of-river hydropower plant

Martin Peter Bieri, Michael Müller

Comme beaucoup d’aménagements hydroélectriques au fil de l’eau, celui de Lavey sur le Rhône en Suisse est affecté de manière récurrente par l’alluvionnement de sa retenue. Outre la gestion sédimentaire, les thèmes abordés par la modélisation concernent éga ...

Ability of One-Dimensional Hairsine-Rose Erosion Model to Predict Sediment Transport over a Soil with Significant Surface Stones

David Andrew Barry, Seifeddine Jomaa

Surface stones affect erosion rates by reducing raindrop-driven detachment and protecting the original soil against overland flow induced-hydraulic stress. The aims of this study were, (i) to quantify how the stone characteristics affect the total sediment ...

Exact solutions of the Hairsine-Rose precipitation-driven erosion model for a uniform grain-sized soil

David Andrew Barry, Seifeddine Jomaa

Hairsine and Rose developed a mechanistic, one-dimensional, precipitation-driven erosion model that, since its appearance, has been validated by several sets of experimental results. The model allows any sediment particle to be present in one of three zone ...

Effect of changes in water level on sediment pore water redox geochemistry at a reservoir shoreline

Janet Gordon Hering, Miles Henry Anderson

Pore water samplers with high vertical resolution were used to evaluate the response of sediment redox geochemistry during transient hydrologic conditions at Lake Powell, a large reservoir in Utah and Arizona, USA. Samplers were deployed at two different y ...
