Analis potensi air tanah di kecamatan lembah gumanti

Abstract

The demand for clean water in the Gumanti Valley continues to increase as the
population grows. On the other hand, the distribution of groundwater continues to
decrease due to the reduction of infiltration areas. Groundwater potential mapping is
conducted to determine the groundwater potential in an area, this is the first step in
identifying and locating local water sources. Remote sensing data and geographic
information systems were used to identify groundwater potential in this study. To
determine groundwater potential, an overlay was conducted using the Weighted
Overlay method. Based on the evaluation results, groundwater potential is classified
into three classes: low, medium and high. Areas with low groundwater potential are
spread over 341 ha, medium groundwater potential areas are 19,265 ha and high
groundwater potential areas are 5,065 ha. The map results obtained can be used as a
reference in finding suitable locations for exploitation of groundwater resources.
