Assessment of water balance distribution based on remote sensing

The importance of water balance studies has emphasized from the need to grasp the actual condition of water resources and environmental changes including climatic changes. The present paper proposes a method for evaluating the water balance components based on vegetation monitoring from remote sensing data. Here, the evapotranspiration model adopts a direct method by using NDVI(Normalized Difference Vegetation Index) calculated from NOAA/AVHRR data and a detailed description of water balance by using the evapotranspiration over the Korean Peninsula. In the study, areal distribution data sets of water balance components are produced using NDVI and a simplified water balance model.
