The document describes a project called the Integrated Management of the Red Thai Binh river system under change (IMRR) which aims to develop strategies for sustainable management of the Red-Thai Binh River System in Vietnam. The project uses integrated water resources management, participatory planning, and modeling and optimization tools. It also involves capacity building activities like training courses. The project models the river system and reservoirs using various tools and analyzes how climate and water demand changes could impact the system and affect flood damages, water supply, and hydropower production. It explores how policies may need to adapt to different future scenarios.
