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>The vulnerability to internal erosion of a 100-year old typical British embankment dam without filters has been examined using seven methods. Four assessed the potential of the shoulder fill, a low permeability till, to act as a filter and prevent erosion ...

<p>The European Working Group on Internal Erosion presented its Interim Report at the 7th European Conference on dams in Freising in Germany in September 2007, this being the culmination of interactions which had ommenced in 2004. This paper summarizes the ...

<p>Roller-compacted concrete (RCC) is used throughout the world for new dam construction. In the United States, RCC is also used extensively for modifying dams with safety deficiencies including stability buttresses for concrete dams, overtopping protection ...

<p>This paper provides, in tabulated and summarized forms, details from a total of 23 North American dams and levees which have been remediated against seepage and the consequences of seepage, by using some form of &ldquo;positive cut-off.&rdquo; The purpose ...

<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 ...
