introduction: the greatest part of constructed dams belongs to embankment dams and there are many examples of their failures throughout history. about one-third of the world’s dam failures have been caused by flood overtopping, which indicates that flood overtopping is an important factor affecting reservoir projects’ safety. moreover, because of a poor understanding of the randomness of floods...

The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...

Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. Recently, the technique of Interferometric Synthetic Aperture Radar (InSAR) has proved its potential to measure ground and structural deformation. This geodetic method represents a cost...

The article describes the definition of filtration flow gradients in dam's body on example Kattakurgan reservoir, analysis reasons for their change cross-section. Evaluation aggressiveness plays an important role ensuring stability reservoir dam and its parts. To assess body, it is necessary to know action pattern water effect elements dam. In addition, chemical composition piezometers was anal...

INTRODUCTION Bioecological aspects of anophelines (Diptera: Culicidae) near areas under the direct influence of the hydroelectric plant reservoir of Serra da Mesa in Goiás, Brazil, were analyzed. METHODS Samples were collected at the surrounding dam area during the phases before and after reservoir impoundment. The influence of climatic and environmental factors on the occurrence of Anopheles...

The paper presents a study on developing an optimum reservoir release policy by using ABC algorithm. The decision maker of a reservoir system always needs a guideline to operate the reservoir in an optimal way. Release curves have developed for high, medium and low inflow category that can answer how much water need to be release for a month by observing the reservoir level (storage condition)....

Environmental restoration is not simply a practical matter. The topic carries with it immense of metaphysical and aesthetic interest. In the same way that the science of ecology and cultural phenomenon of environmental politics are inseparable, restoration of the environment is inextricably tied to and informed by several areas of discourse: ecology, cultural ecology, human ecology, environment...
