Abstract

AbstractFloods during the rainy or monsoon season are typical for Thailand. Flooding occurs when a significant amount of water overflows a shoreline and floods cities and agricultural areas. Losses can be substantially reduced if the flow of the river system is managed appropriately. The objective of this work is to solve the flood forecast problem by formulating a time‐varying optimization problem with ODE constraints to manage the river flow. We demonstrate our concept in the province of Ubon Ratchathani, one of the most flooded areas in northeastern Thailand. The results illustrate that our proposed method will enable operators to efficiently forecast, monitor, and operate the entire river system to mitigate flood risk. Our method is simple and computationally inexpensive, which means that it can be applied to real‐time monitoring systems. Moreover, it is a generalized model that can be extended to a more complicated river system.
