Application of Optimal Search Theory in the Detection of Water Pollution Accident Source

The distribution method of the monitoring effort is studied by using the optimal search theory to detect the water pollution accident source for a suddenlyoccurred pollution event in the river basin. For the sudden accident by characteristic contaminants in medium-sized river, the research sets the target distribution and the detection function, and builds the optimal search model of detecting the water pollution accident source, then finds the optimal search plans. The plans can maximize the probability of detecting the water pollution accident source subject to a fixed time.
