This study focuses on assessing two crucial aspects, seepage, and stability, in the analysis of the zoned earth dam of the Khamhar Pakut reservoir project in the Raigarh district of Chhattisgarh. The evaluation involves finite element analysis using GEO STUDIO software on a specific cross-section (CH 28) of the reservoir project. The study brings out findings for the long-term stability analysis of the dam's upstream slope under a total head of 20.85 m(steady-state seepage) and drawdown conditions. During steady-state analysis, the phreatic line and the total water head gradually decrease as water flows from the dam's downstream side. In contrast, during the rapid drawdown, the total head and water pressure decreased rapidly over time; accordingly, the factor of safety rapidly reduced from 1.77 to 1.15 within the first 12 h. In the case of slow drawdown, the total water head and pressure head decrease gradually, and after the 30th day, they become lower than in the rapid drawdown case. Furthermore, in this case, the factor of safety changed from 1.77 to 1.28 over 8 days. Overall, this study highlights the critical importance of different drawdown conditions considering seepage and stability of earth dams.
