Design and Construction of Earth Dams
Jeffrey Havelin, P.E.
Overview
This
course presents fundamental principles underlying the design and construction of
earth and rock-fill dams. The general principles presented herein are also
applicable to the design and construction of earth levees. The objective of this
course is to present guidance on the design, construction, and performance
monitoring of and modifications to embankment dams. The design and construction
of earth and rock-fill dams are complex because of the nature of the varying
foundation conditions and range of properties of the materials available for use
in the embankment.
The increased development and expansion of the population in the Nation’s
watersheds have created a definite need to develop additional water supply. In
many areas the existing national infrastructure can not meet these needs. The
increase in urban development has also had a negative impact on water quality.
The public is asking that preservation of the environment be an equal goal with
the economic benefits of water resources projects. Since the current
infrastructure is not meeting public needs, this situation is placing lives,
livelihood, and property at risk. Several options are available to provide the
additional quantity of water. The simplest and most cost-effective method to
obtain the quantities needed is to add additional storage at existing dams.
The student must take a
multiple-choice quiz consisting of thirty (30) questions at the end of this course
to earn PDH credits.
