Satellite data have been used for temperature modeling both in urban areas and water. This paperstudies viability of ASTER satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. This study is focused on Dez dam reservoirresiding in Khuzestan province, south west of Iran. After the image corrections required...
