A river basin management plan is widely considered an important tool for supporting the sustainable development of water resources. Cambodia’s Water Law mandates the Ministry of Water Resources and Meteorology to oversee river basin planning in collaboration with all concerned ministries.
Water simulation models help river basin managers and river water users to confidently plan, develop, and sustainably manage water resources. This STB outlines the main types of water simulations models used for water resources management and their value for understanding the status of water in each river basin to ensure sustainable infrastructure and economic development.
To manage water resources effectively it is important to understand how much water is available to support irrigation, energy production, urban and rural water supply, industry, the natural environment, etc. Changing climate and development pressures (e.g. irrigation expansion) will continually impact the availability of water.
One of the first steps is to determine the selection criteria for identifying schemes to be rehabilitated or constructed. These criteria are used to inform an initial list of project areas and potential irrigation schemes to be considered. CAVAC developed its selection criteria based on the lessons learned during the implementation of its first phase (2010-2015).
