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...

Hydraulics has been at the forefront of science for centuries. In this paper, new exciting developments are presented in terms of energy dissipation and multiphase flows. These include the hydraulic design of rectangular dropshafts and stepped chutes for embankment dams, and new air-water studies of spillway flows and dam break waves. The findings demonstrate innovative hydraulic research which...

Aging infrastructure in the US has gained quite a bit of attention in the past decade. Being one type of a critical infrastructure, embankment dams in the US require significant investment to upgrade the deteriorated parts. Due to limited budgets, understanding the behavior of structures over time through risk assessment is essential to prioritize dams. During the risk assessment for embankment...

Effective river ecosystem management requires that the existing hydrologic regime be characterized in terms of the natural hydrologic regime and the degree to which the human-altered regime differs from natural conditions. This is known as Range of Variation Approach (RVA) and can be used for variation of stream flow, range of variation and appraisal of dam impacts on riparian zones. In this pa...

the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...

In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the compariso...

Transformers in power plants act as intermediaries between the power plant and the power grid, which are affected by electrical stresses such as switching, thermal stresses such as overload and arc, and chemical reactions in the dielectric oil. Acid and moisture components cause deterioration of transformer oil and paper insulation. Condition assessment of transformers is a method to predict an...

The seepage and slope stability are very important and necessary in the dam dirt are, therefore, in this context, numerous applications to predict and calculate the rate of leakage has been prepared that than the experimental time and cost savings for the analysis of liquids before construction of earth dams need. In this study, safety factors for slope stability software Kaboodwal  plaxis two-...
