Dams in countries with cold climate are subjected to ice loads during the winter, and these may have significant influence on the dam stability. The design value of the horizontal ice load varies between 50 – 200 kN/m from the South to the North of Sweden, according to the Swedish guideline for dam safety (RIDAS 2011). However, the size of the ice load cannot be dictated by the geographic locat...

In this paper, we consider the optimization of temperature conditions and thermo-stressed state a concrete gravity dam made extra lean roller-compacted constructed in climate corresponding to Pskem HPP Republic Uzbekistan. We show need take into account effect solar radiation on heating mass during layer-by-layer construction dam. A methodology was used estimate radiation, considering cloud cov...

The effect of solar radiation on thermal distribution in thin high arch dams is investigated. The differential equation governing thermal behavior of mass concrete in three-dimensional space is solved applying appropriate boundary conditions. Solar radiation is implemented considering the dam face direction relative to the sun, the slop relative to horizon, the region cloud cover, and the surro...

Ethiopia began constructing the Grand Ethiopian Renaissance Dam (GERD) in 2011 on Blue Nile near borders of Sudan for electricity production. The dam was constructed as a roller-compacted concrete (RCC) gravity-type dam, comprising two power stations, three spillways, and Saddle Dam. main is expected to be 145 m high 1780 long. After filling estimated volume water bounded about 74 billion m3. f...

In recent years a number of embankments were designedwith concrete overtopping protection shaped in a stepped fashion. During large overflows on stepped chutes, there is no skin friction between mainstream and steps, and flow resistance is basically form drag. Alterations of flow recirculation and of fluid exchanges between free-stream and cavity flow are discussed in this study. A comprehensiv...
