Use of Trapezoidal Weirs for Determining Seepage Discharge through Earth Dams
The paper presents a comprehensive analysis of the application of trapezoidal weirs coupled with automated measurement systems for the precise determination of seepage flow rates through earth dams at hydroelectric power plants. A key focus is placed on the hydraulic operating modes of these weirs, particularly the distinction between non-submerged and submerged conditions. The paper details the results of extensive laboratory studies conducted to quantify the impact of submergence on the discharge capacity of trapezoidal weirs.
