This study aims to assess the net benefit of kaptai dam on Karnafuli river in Kaptai, Chittagong, Bangladesh. Kaptai Dam, only hydroelectricity power source Bangladesh, provides 5% electricity demand The Dam is located River at Rangamati District, 65 km upstream from Chittagong. It an earth-fill or embankment with a reservoir water storage capacity 11,000 skm. Though Dam's primary purpose gener...

It is important to determine the hydraulic boundary eigenvalues of typical embankment breaches before carrying out research on their occurrence mechanisms and assessing repair technology. However, it difficult obtain conditions levee accurately with minor or incomplete measured data due complexity instability breach. Based more than 100 groups domestic foreign test embankment/earth dam failures...

This case study presents an application of a conditional transition probability method for interpreting subsurface stratigraphy the interbedded alluvium underlying Perris Dam, and evaluating effects stratigraphic uncertainty on nonlinear dynamic analysis (NDA) results design earthquake loading. The challenges involved in synthesizing information from different sources (i.e., geologic conditions...

Abstract Dams are built to store the water flowing from upstream downstream. Sedimentation and siltation some of major problems affecting storage capacity dams. For effective management, bathymetric topographic data used assess this challenge. In Mambila Plateau Taraba, Nigeria, Tunga Dam is a multifunctional reservoir that serves as small hydropower, irrigation domestic use dam. Nonetheless, i...

seismic behavior of a rockfill dam with asphalt-concrete core has been studied utilizing numerical models with material parameters determined by laboratory tests. the case study selected for these analyses, is the meyjaran asphalt core dam, recently constructed in northern iran, with 60 m height and 180 m crest length. the numerical analyses have been performed using a nonlinear three dimension...

This paper presents promising new technologies for soft ground improvement which include the low improvement ratio cement column method (LCC) and the lightweight banking method using foam mixed soil (LFS). As a measure to reduce settlement and lateral deformation due to road embankment loading on soft ground, the column type deep mixing method used at a low improvement ratio of around 10-20% th...
