Probabilistic Water Quality Control Policies

Probabilistic programming model for regional water quality management in the Hsintien River in Taiwan is presented and is found desirable for problems involving stochastic quantitiies. Four water quality management policies have been studied for the requirement of maintaining a desired minimum dissolved oxygen level at all the reaches of the river. In addition, a trade-off between the operating cost and degree of reliability for a target dissolved oxygen concentration at the Hsintien River was also studied. Finally, the study included the monthly optical wastewater removal scheme for the Hsintien River and the scheme showed significant savings in cost.
