Operational Reservoir and Dam Monitoring and Forecasting System using Multi-Basin Model And Space Techniques in the Greater Mekong Region (GM-ResDam v1)
Abstract
As dams and reservoirs are expanding enormously in the transboundary, poorly gauged and highly regulated Greater Mekong region, GIS-based data portal (GM-ResDam v1) is used to support various end-users in monitoring and forecasting regulated streamflow. At the backend, an operational multi-basin model GM-HYPE v1.4 is used, together with reservoir information generated from a cloud-based Citizen science approach for monitoring reservoir operation from space (CERES). GM-HYPE v1.4 has been set up across the region with an integrated reservoir operation scheme to predict regulated streamflow across a hundred of gauged and ungauged reservoirs in the region. Given a big gap between number of reservoirs in global and local dam databases, CERES can supplement more detailed and the most updated reservoir operation information for existing global reservoir databases. The portal provides reservoir area-elevation-volumes curves; near-real-time monitoring of daily reservoir elevations, storage volumes; near-real-time monitoring and seasonal forecasts of daily reservoir inflows and outflows to assist decision makers, reservoir operators, and citizens in making plans. The portal also provides model performance in different metrics to show the quality control of the provided data and guidance for wider uptake of the data by end users.
