The Miami Conservancy District built five flood control dams after the catastrophic flood of 1913 in Dayton, Ohio. Lockington Dam was one of these five hydraulic fill structures. The Ohio State Department of Natural Resources (ODNR) issued new regulations in 1981 requiring that design flood for class I dams be considered equal to the Probable Maximum Flood (PMF). Flood routing studies performed...

The Study of river water quality interation with lakes and dam reservoirs is important from anexploitation point of view. When river water with different densities enters a lake or dam reservoir,underflow density current phenomenon occurs. Because of the density, so understandingdifferent arrays of this phenomenon Seems necessary for checking erosion and sedimentationprocesses and their managem...

Earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. Earth dam consist of different parts that one of the main parts is clay core. Choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. The objective of this research is to optimize the geometry of earth dam clay core such ...

This paper reviews involuntary resettlement resulting from dam-building, which has been ignored relative to the dominant focus of migration research in China, rural to urban migration. Reservoir resettlement in China has a long history, often of misery and hardship for those displaced. Relocatees affected by the Three Gorges Project (1994– 2009) on the Yangtze River face a similar situation. In...

This paper provides an overview of structural and non-structural alternatives for accommodating larger floods at dams. The first two alternatives discussed, raising the height of the project and/or lowering the reservoir pool, can be used to prevent overtopping by increasing the available floodwater detention storage in the reservoir. Data gathered by an ASCE task committee survey on modificati...

Water reservoir programming studies aim to determine the final cultivated land area based on predefined agricultural models and water requirements. Dam utilization rule curve is also provided in such studies. The system of Dez dam water resources was simulated applying the basic information in order to determine the capability of its reservoir to provide the objectives of the performed plan. As...
