Abstract:
Current progress of remote sensing technology capable describe the spatial scale can be used as a drought monitoring. The purpose of this research are to analyze variables used for monitoring drought such as Latent heat flux (L), Bowen Ratio (BR), Evaporative Fraction (EF), and Evapotranspiration (ET), using Surface Energy Balance (SEB) method from Landsat 7 ETM satellite and GIS application. The drought monitoring in Indonesia especially Bandung that located in tropical region is very important, because the drought area in dry season is increasingly widespread that indicated by reduced of water sources, irrigation, fisheries and groundwater. The land cover classification result in Bandung dominated by plantation (49%), then forest 19%, open land 14%, residence 9%, paddy field 6%, water body 2%, cloud 2%, and industry 0.7%. The high value of L, ET and EF was found in vegetated area (forest, plantation, paddy field), water body, and cloud, and otherwise low value in the dry (non-vegetated) area (residence, industry and open land). Instead of BR value will low in the vegetated area and water body, cloud and high in non-vegetated area.
