| description | Climate change and land use changes are significantly impacting the hydrological cycle, influencing the availability and quality of raw water. This study investigates the changes in rainfall patterns, temperature, and land use in the Cirasea Sub-watershed and their effects on water resources for the Tirta Raharja Water Utility, focusing on the Cibangoak Intake. The research utilizes climate projections from three Global Climate Models (MPI-ESM1.2-HR, MPI-ESM1-2-LR, and GFDL-ESM4) under scenarios SSP2-4.5, SSP3-7.0, and SSP5-8.5. Downscaled climate data, combined with historical rainfall, discharge, water quality, and land use data, provided insights into localized trends. Statistical methods like Quantile Mapping, Mann-Kendall, and Spearman Rank tests were applied to detect climate trends, while correlation analysis assessed their impacts on water quality and discharge. Findings show increased rainfall during wet seasons positively correlates with discharge levels, BOD (Biochemical Oxygen Demand), and Fecal coliformforms, while temperature changes negatively correlate with discharge and TSS (Total Suspended Solids). Agricultural and settlement land use are linked to higher TSS and BOD, respectively. Projections for 2025 to 2045 suggest rising rainfall, temperatures, and land use changes may further influence the quantity and quality of raw water at the Cibangoak Intake. |
