Dam Engineering: State of the Art and Practice, Observed Behavior and Future Challenges

Abstract

It is important to analyze embankment dams behavior from the past lessons learned. It is noticed that modern embankment dams withstand the design earthquake without significant damages. In spite of this situation it is important to prevent the occurrence of incidents and accidents of embankment dams for static and seismic scenarios and so a deep understanding of the triggering factors is needed.

Well documented case histories from many parts of the world related with embankment dams behaviour, under static and seismic actions, were carefully selected and are discussed. The background of embankment dam engineering history is presented.

Based in the governed factors attention is given to the requirements for materials characterization.

The design and the analysis of dam stability under static and seismic conditions are addressed. The reservoir triggered earthquakes and the causative factors are discussed. Dam monitoring and inspections of dams are presented. Ageing effects and rehabilitation of dams are analysed.

The risks associated with dam projects are discussed. The benefits and concerns of dams are presented. It is important to develop new ways of thinking.
