Changma Reservoir


An accelerated rate of sediment accumulation was projected at the proposed Changma reservoir, Shule River, Ganzu, China. This reservoir in the Gobi desert will supply an irrigation area of 220,000 ha. Three different mathematical and physical modeling studies had produced conflicting conclusions regarding the problem and the efficiency of the proposed flushing technique. Based on two site visits and a review of the assumptions and methodologies used in the different studies, Dr. Morris recommended an analysis program to finalize the design work.
