Abstract:
A one-dimensional hydraulic and water quality model was developed to simulate the sudden water pollution accident in the main channel of Middle Route of South-to-North Water Diversion Project. In consideration of the migration velocity of pollutants and water level variations in the channel, the emergency control strategy of each gate was proposed under the conditions of sudden water pollution accident, the gate closing rules were established, the variations of channel depletion rate, stabilization time, water level fluctuation, and water quality were simulated, and then the control scheme of emergency gate was determined to ensure safe operation of channel under sudden water pollution accident. The results can provide reference for the development of emergency strategy in the Middle Route of South-to-North Water Diversion Project.
