The Chao Phraya Delta of Thailand has both problems of water shortage and flooding. There are many gaps between the ideal concept and the present methodology of water management. It is essential to achieve a stable and fair water supply for cultivation in the dry season. Available water resources for cultivation should be maintained and developed by saving water. The authors propose improving methods of water allocation planning and practical water operation, and also comment on flood control. The proposals are limited to measures that can implement within the authority of the Royal Irrigation Department (AID). The proposals refer to upstream dam operation, effective use of side flow, release from the diversion dams, water allocation for cultivation, frequent regulation of main intake regulator, effective use of rainfall in the field, and so on. Their aim is to provide useful ideas for water management based on present experience. The proposals are worthy of being implemented now, basically because they do not need much special budget allocation, they do not have any negative impact in particular, and they will contribute to carrying out water management with greater accountability. The Modernization of Water Management System Project started the development of a decision support system for practical water management to realize some of the proposals.
