In this study, a structure that can effectively prevent overtopping caused by abnormal rainfall was installed in deteriorative agricultural reservoir, and seepage characteristics were compared analyzed through model experiments numerical analysis. The experimental conditions observed installing stepped gabion, vertical parapet combination with gabion retaining wall, geomembrane, core on the dam...

<p>Leakage or seepage in reservoirs and dams has the potential for structural instabilities persuaded by water leakage pathways linked to economic consequences. An environmental isotopic hydrochemical research was conducted determine source origin of seepages on tunnel Pandanduri dam, Lombok Island, Indonesia. This study aimed examine leak dam site at point based chemistry data stable iso...

Prolific natural hydrocarbon seepage occurs offshore of Coal Oil Point in the Santa Barbara Channel, California. Within the water column above submarine vents, plumes of hydrocarbon gas bubbles act as acoustic scattering targets. Using 3.5 kHz sonar data, seep distribution offshore of Coal Oil Point was mapped for August 1996, July 1995, and July 1973. Comparison of the seep distributions over ...

relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. relief wells are often used in combina...

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...

The current research of nonlinear seepage theory of shale-gas reservoir is still in its infancy. According to the characteristics of shale gas in adsorption-desorption, diffusion, slippage and seepage during accumulation, migration and production, a mathematical model of unstable seepage in dual-porosity sealed shale-gas reservoir was developed while considering Knudsen diffusion, slip-flow eff...

Owing to the randomness in the fracture flow system, the seepage system beneath a complex rock mass dam is inherently complex and highly uncertain, an investigation of the dam leakage by estimating the spatial distribution of the seepage field by conventional methods is quite difficult. In this paper, the entropy theory, as a relation between the definiteness and probability, is used to probabi...

Clay core dams are widely applied in reservoir construction, regulating water resource and provide electric power. Leakage is a common problem the leakage amount, which not only affects economic benefits of project, but also relates to safety dam body, difficult estimate. According Darcy’s law stable seepage theory, an analytical method can be proposed calculate clay gain flux short time. By ma...

Seasonal subsurface temperature monitoring, which exploits the fact that increased seepage flow may locally alter distribution, is a useful approach for leakage monitoring and evaluation within embankment dams their foundations. At Mactaquac Generating Station, New Brunswick, Canada, spatial temporal variations of have been monitored modelled at steeply inclined interface between compacted clay...

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...
