ECOHYDROLOGICAL MODELING OF BEAVER DAMS
… of beaver-dominated landscapes. Beavers build dams that modify the water balance and modulate streamflow through different flow states, which might result in drought and flood mitigation. To date, four published hydrological models have been developed to predict these impacts; however, these …

Free vibrations of inflatable dams
This work deals with the linear two-dimensional free vibrations of an inflated cylindrical membrane. An air-inflated membrane is considered first. Vibration frequencies and modes are determined for various cases. The lowest mode shape is anti-symmetric. In the rest of the work, the membrane is …

Breaching of earth embankments and dams
… and growth through earth flood embankments or dams. The improvement of breach model accuracy has made slow progress over the past 20 years, with confusion around breaching processes arising from a lack of appreciation of soil mechanics interacting with hydraulics and structural behaviour. The …

Power and Dams in Central Asia
… planned construction of the Rogun and Kambarata dams in Tajikistan and Kyrgyzstan, the research looks at the various forms of overt and covert power shaping interstate relations and at the way hegemonic and counter-hegemonic measures are put in place in an international river basin. The …

Hydraulic Fracturing in Earth Dams (Boreholes)
The proposed mechanisms of hydraulic fracturing in earth embankment dam cores and boreholes published by various authors have been outlined and compared in this investigation. An experimental study was conducted which reinforces the fact that hydraulic fracturing in boreholes is a tensile …

Ambient vibration testing of concrete dams
… from ambient vibration testing of two concrete dams namely; Roode Elsberg and Kouga dams.

Nonlinear vibration analysis of inflatable dams
In recent years the use of inflatable dams has become more widespread throughout the world. Various people have done studies on the shape and membrane tension of these structures; however, only a few authors have considered dynamic behavior. Due to the nature of the applications and the material …

Cross check survey : World Commission on Dams
The World Commission on Dams (WCD) has completed a global survey of the performance, impacts and decision-making aspects of 125 large dam projects - th Cross-Check Survey. The primary aim of the Survey was to determine broad patterns and trends indicative of past performance, impacts and …

Vibration Analysis of Single - Anchor Inflatable Dams
Inflatable dams are flexible, cylindrical structures anchored to a foundation. They are used for a variety of purposes, e.g. diverting water for irrigation or groundwater recharging, impounding water for recreational purposes, and raising the height of existing dams or spillways. The vibration …

Experimental investigation on the dynamics of inflatable dams
… of pressurized cylindrical membranes used as dams are considered here. Single-anchored air-inflated membranes are predominantly studied. Load combinations are considered without any water, with impounding water, and with water overflow. The two major experimental variables are the dam's …
