<p>This research was set with the objective of investigating the possibility of constructing Roller Compacted-Concrete Dam, RCCD, using local material to reduce its cost. Trial laboratory concrete mixtures were conducted to define RCCD proportions in stage-I. ...

<p>Following an overview of pertinent literature, this paper presents a new methodology for estimating seismic coefficients for the performance-based design of earth dams and tall embankments. The methodology is based on statistical regression of (decoupled) ...

<p>This paper deals with probabilistic slope stability analyses of earth-fill dams. Hydraulic conductivity, unit weight, cohesion and internal friction angle of the soil are considered as random variables. Seepage flow through the dam body is solved by Monte ...

<p>The original design of a dam may be reevaluated for a number of reasons, including the occurence of an incident or unusual load, the availability of new information, the refinement of certain design requirements or guidelines, the adoption of risk-based ...

<p>This study was carried out in selected districts of Mashonaland, East and Central provinces of Zimbabwe in 2011 to determine the environmental impacts of earth dam failures and spillway malfunctions with regards to soil erosion. A total of 14 earth dams ...

<p>The Mw=9.0 Tohoku Earthquake resulted in failures of the two dams impounding Fujinuma Lake, in Fukushima Prefecture. After the event, several mechanisms were postulated regarding the failure modes of the dams. The authors have performed numerical dynamic ...

<p>ANUGA software is used to simulate the 1928 St. Francis dam break flood. ANUGA (see https://anuga.anu.edu.au/) is a free and open source software, which is designed to simulate shallow water flows. Our simulation assessment in this paper is based on the ...

<p>Potential Failure Modes Analysis (PFMA) and similar processes have become a fundamental part of dam safety program efforts for many organizations in the United States and around the world. In the PFMA process, the credible threats to the safety of a dam ...

<p>The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability ...

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 ...
