Overview

Randomized trial evaluates hydraulic conductivity changes in small earth dams, indicating significant seasonal impacts.

Key Points

  • This study aims to evaluate how changing river water levels affect the filtration system stability at small earth dams over ten years.
  • Analyzed daily water pressure data from 2015 to 2025 using GeoStudio (SEEP/W).
  • Conducted four steps: data gathering, computer modeling, seasonal decomposition, and validation calculations.
  • Applied seasonal models for winter and summer to assess hydraulic performance.
  • Cumulative Nash-Sutcliffe efficiency values were 98% for the winter model and 95% for the summer model.
  • Effective permeability reduced by nearly 88% during summer low water levels compared to design values.
  • Significant differences were found between theoretical and real conditions of hydraulic permeability.
