Abstract

In order to enhance the desilting efficiency by density flow in reservoir, we conducted systematic research on the formation, running, and application of density flow for the desilting of Kizil Reservoir in Xinjiang, and gave the quantified ranges of physical indicators of density flow. Furthermore, we proposed engineering measures such as combining dyke and canal, and controlling reservoir water level to create conditions for density flow. Practice proved that the proposed measures are of remarkable desilting effect. This research offers theoretical basis and practical experience for the desilting of reservoir by density flow.

Key words
