In this paper, the Guangxi’s red mud disposal field is taken as the study area. Appropriate calculating parameters and boundary conditions were selected based on the survey data to build a Mohr-Coul0mb and fluid model under the plane-strain condition. FLAC software was adopted to simulate the distribution of pore water pressure, filtrate seepage paths, and leakage of the dam body under conditio...

SYNOPSIS. The leakage of water from a dam suggests a number of possible scenarios, and none of them are good. At best, the reservoir owner is losing the power-generating potential of the escaping water. At worst, the leakage may be the precursor of dam failure. Among the technological advances that will enhance the safety and efficiency of hydropower in the future, is a remarkable breakthrough ...

seepage in earth fill dams is one of the important factors that may cause the erosion and slope instability if it is ignored. therefore, it is crucial to calculate the leakage discharge through the body of dam and foundation, to prevent economic and life hazards by considering technical and economical issues. in this research, the seepage analysis of the body and the stability of the upstream a...

In recent years, carbon dioxide capture and its geological storage (CCS) has been recognized as one of the most effective tools to mitigate climate change with its vast potential and cost effectiveness. With this background, many countries around the world have started to study on its technical aspects as well as economic aspects. In some countries, several commercial or experimental plants are...

Synthetic Aperture Radar (SAR) technology has the ability to image surface oil seeps that originate by slow leakage from oiland gas-filled traps. Multi-temporal satellite data over such seeps delineate prospective areas and provide the locations for follow-up surface sampling from which key geochemical information of the reservoir oil can be obtained. Satellite radar can offer the oil industry ...

Previous studies indicate that the local aquifer systems in the Mid-Levels, a highly urbanized coastal area in Hong Kong, have commonly been affected by leakage from water mains. The identification of leakage locations was done by conventional water quality parameters including major and trace elements. However, these parameters may lead to ambiguous results and fail to identify leakage locatio...

This study determines the effects of leakage attributed to conduit defects on failure behavior downstream slope a homogeneous reservoir. To analyze mechanism, model experiments and three-dimensional deformation–seepage analysis were conducted based shape, pore-water pressure, hydraulic gradient, settlement, results compared with changes in water storage capacity failed reservoir owing defects. ...

Leakage is a major safety issue that, if left unchecked, may result in dam failure by various mechanisms. There is enormous pressure on dam operators to repair leaks without significant delays. Frequently, the need to reduce the risk of failure or control water loss has led to costly remedial repairs that are planned and executed without a complete understanding of the problem. A lack of approp...

Lessening the leakage of surface water can reduce the waste of water resources and ground water pollution. To solve the problem that Mengxi River could not store water enduringly, geology investigation, theoretical analysis, experiment research, and numerical simulation analysis were carried out. Firstly, the seepage mathematical model was established based on unsaturated seepage theory; second...

Abstract: The seepage control system of a high Concrete Face Rock-Fill Dam (CFRD) may have anti-seepage deficiencies during both construction and operation. In order to solve these, the three-dimensional Finite Element Method (FEM) model was built based on dam body filling, anti-seepage system, defect location and bedrock distribution. The seepage field simulation and computation were carried o...
