Abstract

The utilization of water resources for various necessities keeps increasing from year to year, as the impact of the growth of population and the development of the activity. Dams have great benefits and keep great potential danger and risk of physical damage and failure function. This study aims to determine the water discharge that seeps through the body of the dam and the foundation of the Pandanduri Dam. The Electrical Resistivity Tomography (ERT) method uses multiple electrodes to measure resistivity value and pattern distribution on the subsurface material. The finite element method uses SEEP /W software. Seepage analysis was carried out on steady flow (steady seepage) at a reservoir water level of 276.78 m. This research shows that Pandanduri Dam has multiple zones on the dam body with a score of low resistivity of 5 Ω–25 Ω and is identified as a dangerous seepage dam. The analysis results are the seepage discharge below the body dam, calculated with a SEEP/W of 1.204 l/sec, and seepage on the dam must be more minor from a provision of 1% of the annual inflow (3.19 m3/s), so the seepage discharge maximum allowable is 31.9 l/sec. The full seepage discharge measured in the v notch is 0,88 l/sec. The seepage on the dam is more minor than the permissible seepage discharge, so the seepage discharge through the dam body is safe for the dam.
