This chapter presents the main abrasive effects observed in concrete hydraulic surfaces of dams of hydroelectric power plant (HPP). These types of hydraulic structures are subject to solicitations for dynamics order due to water flow at high speed usually ...

<p>More and more old dams are operated for more than 50 years. Evaluation on the life span and the real safety status becomes a challenging task for the dam society, especially for China because of more than 6000 dams to be evaluated and rehabilitated within ...

<p>Although decreased funding and increased environmental regulations have put the brakes on new dam construction in the United States, dam safety remains a crucial concern. Many dams, especially earthen embankment dams constructed prior to 1960, do not meet ...

<p>Roller-compacted concrete (RCC) has become a popular method for providing spillway and overtopping protection for earthen dams. Over the past 27-years, RCC has been used as a spillway or overtopping protection for more than 130 dams. In addition to providing ...

<p>Little information is provided on the energy dissipation that occurs in stepped spillways with slopes less than or equal to 22&deg; (slopes commonly found among NRCS constructed spillways). Renwick Dam in North Dakota falls in this unique class of planned ...
