Abstract |
It is important to introduce a local adaptive water supply system for upper mountainous regions, which provide a margin of water supply. This can be done through the process of securing a water source, planning for optimal use, and combining it with a water source that can be linked. In particular, in a mountainous region located at the uppermost part of the watershed, an approach should be found to utilize the groundwater discharge supplied through valley water and lateral discharge. This study sought to improve the water supply system using sand dams in drought-prone areas in Chuncheon, in Gangwon Province. Our approach involved virtually installing a sand storage tank under the existing water source to perform modeling in consideration of the current water intake and calculating the amount of water that can be taken from the sand dam. When the sand dam was applied at a size four times larger than the existing water source, it was found that the groundwater drainage increased significantly with changes in water surface slope and hydraulic conductivity. |
