Feasibility analysis of fresh water condition in Mangunan Village - Dlingo Subdistrict after Bantul earthquake of May 27^th 2006

The earthquake of May 27^th 2006 has caused drought to several water sources in Mangunan village. Hence, it needed a preliminary study on the hydrology condition in the aftermath of earthquake in Mangunan Village – Bantul. Methods to identify the hydrology availability and water need condition using data calculation discharge and geometric population growth. According to the measurement result in Mangunan Village, the actual water availability is 128,484 m³/day, which can cover the water requirement to fulfill the need of the people amounting to 657,75 m3/day. Although, in fact, the village potentially has enough water availability with the amount of 14.037,845 m³/day. So, a further research could be done to achieve a stable condition of the dynamic discharge. Groundwater conservation is very needed in this research area. In general, the dry region in the village needs to be planted with vegetation that are resistant to dryness in the region with shortage of water and also with plants that do not absorb much groundwater or soil mosturizer.
