This site is a very informative and well presented resource for dam design, primarily intended to give undergraduates or anyone interested in the subject a solid introduction to the basic concepts. Maintained at the University of Durham in Britain, there are many sections that provide a good overview of the many processes involved in building a dam. Many different types of dams are described in detail, including concrete and embankment dams. Hydrology and geology, important factors that need to be considered when choosing a suitable location, are also covered. The layout of the site is fairly good overall, but navigating the many sections and subsections can sometimes get confusing.
