Abstract
The purpose of this study is to develop a new optimum operation system for large-scale reservoir on science-based which can be easily put into practice in developing countries. The Bhumibol and Sirikit reservoirs in the Chao Phraya River basin (CPRB) in Thailand were selected for this study. After the CPRB had a massive flooding in 2011, the Thai government has been planning new watershed management for the CPRB.
This paper proposed the new useful reservoir operation method. This proposed method used new optimal rule curve determined by historical hydrological data. This paper verified the method using historical hydrological data from beginning of reservoir operation to February in 2015. As a result, the proposed reservoir operation method contributed stabilization of storage volume with minimizing risks of flooding and drought. The proposed reservoir operation method also contributed discharge volume for the irrigation in dry years.
