RESULTS SHOW THAT SUBSTANTIAL SAVINGS COULD BE MADE THROUGH THE APPLICATION OF SYSTEM ANALYSES AND OPTIMIZATION METHODS TO WATER QUALITY PROBLEMS ON THE UPPER REACHES OF THIS CHANNEL. LARGE BENTHAL DEPOSITS CAN APPARENTLY PREVENT AEROBIC CONDITIONS FROM OCCURRING IN THE UPPER CHANNEL EVEN WHEN BIOLOGICAL WASTE TREATMENT IS NECESSITATED FOR ALL WASTE DISCHARGERS.
