Mapping of the Distribution of Aquifier in KawatunaSub-district, Mantikulore District, Palu
2019
Background: The condition of the land in Kawatuna Sub-district is dry, with vegetation overgrown only with shrubs. Dry land condition makes people difficult to get clean water sources for their daily needs. Purpose: This research aims to find out the existence of an aquifer and the depth of the aquifer in Kawatuna Sub-district. Method: The method used in this research is Vertical Electrikal Soundin (VES) with Sclumberger Configuration. The measurement is conducted on 10 measuring points. Data is processed using IP2WIN. Result: The result shown by the program is in the form of distribution of resistivity(ρ), thickness (h), and depth (d) of each subsurface layer. Aquifer layer is shown by the resistivity value of 32.15Ωm-48.03 Ωm and formation factor value of 2-5. This layer consists of sands, pebbles, and sandstones. The upper limit of this later is in the depth of 50.05-72.75m, while the lower limit is undetectable. Conclusion: Aquifer layer is distributed to the east and to the west. It can be seen from the depth of aquifer in the west which tends to be shallower than that in the east. Commonly, this layer is located below the impermeable clay layer.
