Driven by MIKE Powered by DHI, a DSS was developed to support MONRE and VNMC in water resources management of the 2S basins, helping with water resources planning, flood forecasting and reservoir operations. VNMC contracted two consulting firms for the development of the DSS and DHI was hired to help VNMC with the supervision of the implementation of these contracts.
Using MIKE HYDRO River, we simulated more than 1000 km of rivers and included numerous reservoirs and their complex operations. This river model runs in real-time and provides accurate flood forecasts twice a day. A MIKE HYDRO Basin model supports the river basin planning and management based on IWRM principles, providing insight months in advance for the 50,000 km2 catchment. MIKE OPERATIONS was chosen as the central part of this complex system. It manages models in real-time while connecting to a variety of data sources and using a knowledge base developed for this project. A key aspect of this system is its versatility, as it can be easily extended at a later stage to meet future needs.
Water experts are working with the system through a user-friendly web-based interface that was designed to integrate naturally with VNMC workflows and processes. This provides the right level of insight regarding the river flow, flood risk and hydropower dam operation. This information is crucial for both countries to have a common understanding of the river flow (in normal and emergency cases) and to plan water releases from hydropower dams in Sesan and Srepok rivers crossing the border well ahead of time.
