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...

Groundwater and seepage samples were collected from both the natural and building-modified slopes in the highly urbanized spaces of the Mid-Levels area, Hong Kong. Groundwater in the natural slopes, although retaining some signatures from rainwater, is enriched in major cations such as Na, K, Ca and Mg and some anions such as HCO3 and SO4. Clearly, water-rock interactions, such as weathering of...

The topography of inland deltas is influenced by the water-sediment bal-3 ance in distributary channels and local evaporation and seepage rates. In this 4 letter a reduced complexity model is applied to simulate inland delta forma-5 tion, and results are compared with the Okavango Delta, Botswana and with 6 a laboratory experiment. We show that water loss in inland deltas produces 7 fundamental...

Abstract In recent years, the modernization process of cities has been accelerated, and scale basement construction continuously expanded. The groundwater table in southern soft soil areas is usually high, water pressure carried by floor often large, thus accidents leakage from exterior walls occur time to time, which seriously affects safety use function basement. this paper, based on a projec...

Fractured seepage is an important factor affecting the interface stability of rock mass. It is closely related to fracture properties and hydraulic conditions. In this study, the law of seepage in a single fracture surface based on modified cubic law is described, and the three-dimensional discrete element method is used to simulate the dam foundation structure of the Capulin San Pablo (Costa R...

The seepage velocity and temperature externally manifest the changing structure, gas desorption and energy release that occurs in coal containing gas failure under loading. By using the system of coal containing gas failure under loading, this paper studies the law of seepage velocity and temperature under different loading rates and at 1.0 MPa confining pressure and 0.5 MPa gas pressure, and c...

Anopheles arabiensis Patton (Diptera: Culicidae) is considered the most efficient malaria vector in eastern Sudan. This study aims to characterize the breeding sites of An. arabiensis throughout the year in and around Kassala town, eastern Sudan. Diverse larval habitat types were visited and characterized based on the habitat type and chemical composition. Mosquito larvae were found in many div...

The diversity of the landslide dam structure will result in difference body’s seepage. In this paper, based on two kinds soil bodies different particle gradations, fourteen groups structures are designed to generalize seepage developments and breaking processes. study shows that saturation evolution characteristics dam's have a considerable influence dam’s characteristics. An empirical formula ...

One of the main reason of earth-dam breaks is inner erosion which is caused by washing fine soil particles and finally lead to seepage inside the dam. Seepage will decrease effective tension in the earth-dam's core and arching phenomena is occurred. More settlement of core than to shell is the consequence of arching and occurrence of cracking. In this paper, GeoStudio software based on finite e...
