Abstract:


The Lower Mekong Water Basin is the largest river basin in Southeast Asia, home to more than 60 million people. The region has seen rapid population growth and socio-economic development accompanied by deforestation, expansion of agriculture, and stream-flow regulation. The basin supports a large amount of rice farming and other agriculture, which heavily depends upon seasonal flooding. This project created flood impact assessment maps to gain a better understanding of flood-prone areas in the region. They were then compared against other flood-warning products for the area and integrated into the Committee on Earth Observing Satellites Disaster Risk Management Observation Strategy in a Web-based ‘Flood Dashboard.’  These primary goals were achieved using Moderate Resolution Imaging Spectroradiometer (MODIS) 250m products and Normalized Difference Vegetation Index values to derive flood-impact maps
