Abstract

The Luyo area, Polewali Mandar Regency, West Sulawesi Province, has a high dependence on groundwater as the main source of water for domestic and community activities. Increasing groundwater utilization may potentially disturb the natural hydrogeological balance if it is not properly managed. Therefore, a comprehensive understanding of natural hydrogeological conditions is essential as a basis for sustainable groundwater management. This study aims to determine the hydrogeological conditions of the study area, the natural groundwater balance, and the groundwater flow pattern and hydraulic head distribution through natural-condition hydrogeological modeling. The research methods include hydrological analysis, groundwater level measurements, electrical resistivity surveys using the Schlumberger configuration, pumping tests, and steady-state numerical groundwater modeling based on conceptual and mathematical approaches. The results indicate that the hydrogeological system in the study area consists of unconfined and semi-confined aquifers controlled by local lithological and geomorphological conditions. The natural groundwater balance shows that the study area remains in a relatively balanced condition, with groundwater recharge primarily derived from rainfall infiltration. Groundwater flow generally follows the topography, moving from recharge areas toward discharge zones such as rivers and springs. Model calibration results show good agreement between simulated and observed hydraulic heads. The developed natural-condition hydrogeological model is expected to serve as a baseline reference for evaluating future changes in the groundwater system due to human activities and environmental changes

Abstract

This study aims to analyze the effectiveness of drainage in the southern disposal pit dump 4 area. It uses a descriptive quantitative method with primary data collection in the form of actual channel conditions and dimensions, as well as flow velocity measurements using the float method. Secondary data includes rainfall data, disposal design, topography, and mine progress maps. The analysis uses the Mononobe method to calculate rainfall intensity, the rational method based on a 10-year return period to calculate planned runoff discharge, and the Manning equation to determine channel capacity. The results of this study indicate that the actual open channel in the disposal area of pit dump 4 south has a discharge of 0.50 m3/s under light rain conditions and a discharge of 1.12 m3/s under heavy rain conditions, and experiences a decrease in hydraulic performance due to erosion on the channel walls and sediment deposition at the bottom of the channel. Therefore, the current channel cannot accommodate and drain the maximum discharge that may occur under extreme conditions. It is recommended that an open channel with a channel capacity of 8.45 m3/s can accommodate a planned runoff discharge of 7.68 m3/s, which indicates that the drainage system is capable of accommodating and draining water safely, efficiently, and sustainably
