DEVELOPMENT OF WATER RESOURCES MANAGEMENT SCHEME FOR SEDAWGYI DAM USING WEAP MODEL

Abstract
This study aims to improve water resource management at the Sedawgyi Dam using an Integrated Water Resources Management (IWRM) framework. The objectives are to promote efficient water use in hydropower, irrigation, and domestic water supply, and to develop a comprehensive water management plan. Located near the Chaungmagyi stream, the dam supports Mandalay City and its surrounding townships through a complex water distribution network.The Water Evaluation and Planning (WEAP) model was used to identify significant gaps between water supply and demand. Scenario analyses indicate that future water demand will increase substantially, highlighting the need for proactive measures such as infrastructure upgrades, advanced irrigation techniques, and better groundwater management. Scenario 2 was found to be the most effective for optimizing the water supply system, offering benefits like reducing groundwater extraction, expanding domestic water supply, and sustaining downstream flow without impacting hydropower generation.The proposed water management plan focuses on scenario-based planning and balancing economic development, social equity, and environmental sustainability.
