Determination of the filtration consumption from the body of the soiled dam

Abstract This paper addresses the pressing issues of climate change, population growth, and the imperative for efficient water resource management. It emphasizes the importance of effectively utilizing water stored in reservoirs and accurately assessing water loss. Specifically, the study focuses on quantifying water lost through the filtration process in earthen dam bodies and examining its impact on structural integrity. Measurements were taken at the Chimkurgan reservoir when it reached the upper water level mark (Δ 480.43), assessing the filtration depression curve and the flow rate of water exiting from hydroposts at each piezometer within the dam. Statistical analysis of data collected during field research indicated an average loss of 90 liters per second through filtration from both the body and floor of the dam over a year. This article explores the relationship between filtration water consumption, the depression curve, and the geological characteristics of the dam, providing insights into effective water management strategies.
