3. 3 Objectives 1.The objective of this project is introducing the different types of dams in Saudi Arabia, their advantages and disadvantages, choice of kinds of dam, selection of dam sites, design principles, forces acting, causes of failures and safety measures. 1.Role of dams in regulating the amount of water during the period of drought, flooding, and protecting the infrastructures.

4. 4 Significance to KSA Kingdom worked to secure water from various sources with conservation. One of the most important of those resources in the Kingdom is rainwater which runoff through valleys. To conserve rainfall water, many dams were built through the kingdom for different purposes such as farms irrigation and drinking water supply. Safe design of these dams is very important, where the increase in flood water may cause damage to them.

5. Description Dams are constructed across water ways to create artificial lakes or reservoirs. Dams can be classified according to their use (storage, diversion, detention), design (gravity, arch, embankment, earth, rockfill), or construction materials (rigid, buttress, steel, non-rigid). 5
