Title

INVESTIGATION OF DENSITY CURRENT BEHAVIOR IN RESERVOIR USING HYDRAULIC MODEL

Pages

  87-100

Abstract

 Reservoir sedimentation decreases the useful storage or the useful life of a RESERVOIR. Knowledge of the sediment distribution in RESERVOIRs can be used as a useful tool to discharge them at a proper time. In this study, using a HYDRAULIC MODEL, the concentration of DENSITY CURRENT along the RESERVOIR and the SEDIMENTATION RATE has been investigated experimentally. Two types of sediment particles, sand as non-cohesive and clay as cohesive particles were used Experiments were done for different DENSITY CURRENT flow rates on several RESERVOIR bed slopes to consider the effect of flow rates on sediment particles size distribution and SEDIMENTATION RATE along the RESERVOIR. After sedimentation of most suspended particles, RESERVOIR water was discharged slowly, then, samples were taken from the sediments in proper distances along the RESERVOIR. These samples were transferred to the laboratory for particle size testing and calculation of the SEDIMENTATION RATE. Results were shown that most of the coarse particles were deposited before the plunge point or a short distance down the plunge, while, the fine particles were located between the plunge point and the dam, overall, SEDIMENTATION RATE decreases along the RESERVOIR toward the dam. Equations to calculate SEDIMENTATION RATE and the concentration of DENSITY CURRENT along the RESERVOIR, were introduced.
