Sand Dam Development Directions of Mid-mountain Area for Source Water against Drought

The demand has been increased rapidly about measures regarding the drought in the mid-mountain area, where is a blind area for a water supply because of the continuous drought. However, to date, there is not yet sufficient research for the fundamental solution. A sand dam is a type of underground dam which is installed dam or weir in valley or stream, and secured space is filled with pervious materials such as sand and then store water in that pore. This is can be applied in Korea where is difficult to construct due to stream environment and ecosystem preservation. This study is to analyse the case of designing a sand dam at domestic and foreign and develop the optimised system for water supply and secure source water in the mid-mountain area in domestic where frequent drought damage. The investigate suggests the development directions of the sand dam in the mid-mountain area connected with the existing water installations and erosion control dam which are based on the case of construction in the mid-mountain area connecting with foreign development cases with the erosion control dam and water intake facilities.
