Abstract: Flood waves resulting from dam break and spillway gate malfunction may have dramatic impacts. Two related cases are the overtopping of a dam by flood waves and a sudden water release down a stepped cascade. In each instance, some energy dissipation takes place and classical dam break theory are inappropriate. Both cases were investigated in large-size facilities and in a prototype. Ne...

One of the major issues in dam construction is water seepage, post impounding. Assessment and prediction of the amount of waterleakage can be useful in preventing such events. The Seymareh dam has been constructed on the Seymareh River in Ilam province,Southwest of Iran. The dam controls the floods and generates hydroelectric power. It is already under impoundment and the seepageproblem is bein...

Although field observations of sudden spillway releases highlighted strong aeration of dam break wave flows, no study investigated these two-phase flow characteristics. New original experiments were conducted down a 24 m long stepped waterways. Dam break wave propagation showed an equivalent flow resistance similar to steady flow conditions (f ~ 0.05). Detailed unsteady air-water flow measureme...

In this study the electric power generation from the Kayabogazi Dam has been investigated using Fuzzy logic algorithm to optimize the required power demand. In the implementation of the algorithm the real data recorded by the State Water Works (DSI) which is representing monthly average water flow to the Kayabogazi Dam has been used. An easy and operator friendly control algorithm has been deve...

Paul C. Rizzo Associates, Inc. (RIZZO) has developed efficient computational tools to evaluate the liquefaction potential of earth embankment dams located within high risk seismic regions. Two relevant case histories are the Saluda Dam and the Santee Cooper East Dam Extension, both structures susceptible to liquefaction, and located in South Carolina. Saluda Dam presents liquefaction risks with...

The proposed approach combines the advantages of isogeometric analysis (IGA) and scaled boundary finite element method (SBFEM). The IGA is employed for idealization of the dam structure, while SBIGA is developed for modeling the semi-infinite fluid domain of reservoir and unbounded elastic half-space of the dam foundation. Water compressibility, reservoir boundary wave absorption can be taken i...

background: it is considered that if radon gas is inhaled and ingested, it is the primary health risks for lung and stomach cancers. this paper presents the measurement results of radon activity concentrations both residential tap water and dam water for kastamonu city centre-turkey. materials and methods: the radon activity concentrations of water samples collected from 60 tap waters at four l...

abstract background and purpose: eutrophication is one of the major environmental problems in waterways causing substantial adverse impact on domestic, livestock and recreational use of water resources. aras dam, iran which provides arasful city with drinking water, has chronic algal blooms since 1990. levels of up to 900,000 cells/ml of toxic cyanobacteria (mainly anabaena and microcystis) hav...

This study sought to assess Gweru’s water supply system from the source to the consumer to find out whether the water is safe for domestic purposes, mainly consumption. Water samples were taken from Gwenoro dam (raw water), Gwenoro treatment plant (treated water) as well as from GIS-generated random points of residential areas closest to Gwenoro and furthest from both the dam and the treatment ...
