In present study, the effect of reservoir length on seismic performance of concrete gravity dam has been investigated. Monte Carlo probabilistic analysis has been used to achieve a sensitivity of the responses to variation of truncated reservoir length in finite element model. The ANSYS software based on finite element method is applied for modeling and analysis. The Pine Flat dam in California...

In the far north of Uttar Pradesh Province in the Indian Himalayas; the 280 MW Dhauliganga hydroelectric power plant is under construction by National Hydroelectric Power Corporation ( NHPC ), a stateowned enterprise; and a joint venture of Kajima Corporation of Tokyo and Daewoo Corporation of Seoul. This project sets out to develop the lower section of the mountain cascade of the Dhauliganga r...

abstract among activities that can be used to prevent piping phenomena and reduce seepage and exit gradient are installation of cutoff wall and drain under hydraulic structures. hence in this study, to investigating the influence of each mentioned parameter on uplift force and exit gradient a computer model has developed in which general equation of fluid flow into the isotropic and anisotropic...

It is difficult to obtain reliable shear strength parameters for the stability analysis and evaluation of tailings dams in an unstable state. In this study, sensitivity index safety factor a dam was evaluated. The cohesion C range earth rock state determined by factor, Morgenstern–Price method used inversion. During parameter inversion, uncertainty reasoning established based on cloud theory, w...

Lots of dam failures are the result uncontrolled seepage. The collapse Situ Gintung Dam in Tangerang, Banten-Indonesia 2009 due to heavy rains caused structure collapse. This is increased pore water pressure landfill. To anticipate seepage, it necessary monitor based on behavior changes rainfall and reservoir levels. Seepage within body often monitored using instrumentation tools such as standp...

Ski jumps are frequently applied as spillways of high dams. The resulting jet impact location on the plunge pool surface is often distant from the dam toe so that the latter is protected from scouring. Furthermore, the jet disintegrates and disperses prior to its impact, thereby reducing the specific energy addition to the plunge pool. The present research addresses four aspects, based on three...

There are increasing demands from dam safety regulations and guidelines to upgrade the rockfill dams, especially in Norway where over 180 large dams present. To protect hydraulic structure against overtopping events or leakages, it is important use defence mechanisms such as a protective layer of riprap on downstream slope. In this article, we display 9 experimental setups riprap, conducted at ...

wide variety of timings and techniques has been used based on the housing, production, availability of requirements etc. this current study was done for a morphologic evaluation of the cow's digit in different trimming times. a dairy herd with 2200 milking cow, free stalls barns, average daily production of 36 liters per cow was selected. forty cows were assigned to four groups based on hoof tr...

an anatomic study on ovine hoof to find a proper hoof trimming method was done. fore and hindlimbs of 15, two years old ewes. were studied all legs were transferred to vet college and divided by fore and hindlimbs, left and right and lateral and medial digits. toe height to ground and to the solar surface, heel height, sole length, toe length, toe length to the sensitive tissue, sole thickness ...
