Emergency Control Strategy for Unexpected Water Pollution Accidents in the Middle Route Open Channel of the South-to-North Water Diversion Project

Abstract:

This paper takes a typical channel passage in the middle route of the South-to-North water diversion project as an example to study emergency control strategies for unexpected water pollution accidents. A one-dimensional Saint Venant equation and water quality numerical model is developed, considering limitations such as the migration velocity of pollutants, water level fluctuation, and variations in the channel. Emergency control strategies for each gate are proposed for unexpected water pollution accidents and gate closing rules are established. Parameters such as the channel water depletion rate, stabilization time, water level fluctuation, and water quality are simulated under different control strategies in order to ensure the safe operation of water transport and to decide on the control strategy for unexpected water pollution accidents. Such studies can provide reference information for the development of emergency strategies in the middle route of the South-to-North water diversion project.
