The choice of materials to be used on the construction of earth dams is made in an empirical way, taking into account previous projects and the experience of the involved engineers. An engineer often specifies the materials and their quantities that will be used based on previous projects, on the geotechnical information about the materials available and on common sense. In order to improve thi...

With the continuing pressure on Australia’s water resources and interand intra-annual rainfall variability, farmers, especially in rainfed agricultural and pastoral zones, have been developing farm dams as a mean of providing additional water sources for irrigation and stock. The density of farm dams has increased over time, and an accurate knowledge of the spatial distribution of farm dams is ...

  In order to quantitatively evaluate the sediment yield in ungauged basins, it is necessary to use empirical models. The EPM model, as a model which is using in Iran, has sometimes been evaluated. Most evaluations have often been conducted by using river's sediment information and direct measurements of dam reservoir sedimentation have been less used, while the sediment measurement method on r...

Simplified procedures are commonly employed to estimate seismic displacements of earth and waste fills. The landmark work of Makdisi and Seed (1978) has been widely adopted in practice. Although this work is widely used, it has a number of significant limitations such as decoupling the sliding block analysis from the seismic response analysis, use of a limited number of recorded earthquake moti...

Lake Oroville is a large artificial lake created by the construction of a 235-mhigh earth dam on the Feather River, California, near the city of Oroville. Its storage capacity is about 4.4 × 109 m 3, and its maximum depth is about 200 m. There was no significant increase in seismic activity in the lake region following impoundment of the dam late in 1967 until the occurrence of many small seism...

Cosmologically motivated theories that explain small acceleration rate of the Universe via modification of gravity at very large, horizon or super-horizon distances, can be tested by precision gravitational measurements at much shorter scales, such as the Earth-Moon distance. Contrary to the naive expectation the predicted corrections to the Einsteinian metric near gravitating sources are so si...

The Coralville Reservoir’s capacity is shrinking. Since the dam that created the Reservoir was completed in 1958, approximately 11 percent of the storage basin’s capacity has been lost to silt, said Ron Fournier, a spokesman for the U.S. Army Corps of Engineers. “Construction projects, farming — pretty much any time earth is moved, rain will wash away dirt,” he said. “Then streams fill up with ...

The Red Rock Hydroelectric Project converted the existing Dam near Pella, Iowa, from a non-powered dam into multi-purpose dam. flood control was constructed by U.S. Army Corps of Engineers (USACE) in 1960s on Des Moines River Iowa. hydroelectric project developed Western Minnesota Municipal Power Agency and generates up to 55 MW with an average annual energy output 178 gigawatt-hours. new intak...

Earth dams have been used widely recently in flood and sedimentation control projects and feeding ground waters in country's watersheds and correct locating for such structures is necessary for increasing their efficiency. In this work, it is attempted to determine the correct locations for constricting earth dams in Yoosef-abad watershed in Tabas using v and incorporating information layers. T...
