摘要
The purposes and the types of dams are reviewed in AI-Baha province, on the western south of KSA （Kingdom of Saudi Arabia）. Data are collected and tabulated ascending according to the capacity of storing water. The cost （in Saudi Riyal） is plotted versus the capacity （in m3） for the dams. Then a linear regression analysis is done employing Micro Software Excel. An equation is obtained to predict the cost of dams with storage capacities less than or equal 500,000 m3, where the type of dam has no effect on the cost. Taking into consideration the inflation rates along the time, the 2013＇s costs are estimated and also another equation is obtained to predict the cost.
