Field studies were carried out on the earthen dam of channel reservoir Tuyamuyun hydrosystem Amudarya River (Uzbekistan), which was put into operation in 1984 according to traditional method using control and measuring equipment embedded body dam. The water levels upper lower reaches, piezometers, drainage discharge measured. Maximal 130.00 head race observed middle October minimal 117.00 March...
Earth dams can be a prehistoric phenomenon. These structures are designed to exploit surface water resources in certain positions in natural landscapes. In the plateau of Iran, surface water sources are generally seasonal. Seasons, when surface water flows abundantly, are late winter to the first half of spring. Meanwhile, according to the agricultural calendar, the peak demand for water for mo...
considering the seepage and choosing an efficient sealing method is very important in dam projects. this issue has a close relationship with engineering geological properties of the dam site. chapar-abad dam is an inhomogeneous earth-fill dam of 44.5 meters height, crest length about 427 meters and a reservoir capacity of 127 million cubic meters. the dam project is under construction and is lo...
This research intends to develop a method based on the Artificial Neural Network (ANN) to predict permanent earthquake-induced deformation of the earth dams and embankments. For this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. In order to predict earthquake-induced deformation o...
