Abstract
Abstract Salt-enriched flat areas are known as sabkhas in the Red Sea coasts. Previously classified sabkhas north of Jeddah city, Saudi Arabia were examined by remote sensing techniques. Confirmation of ground studies was reached with the synoptic coverage and spectral characteristics of the Landsat digital data. New maps were produced utilizing satellite data; this may include geomorphological and sabkha zonation maps. False colour, ratio and principal components composites were used in this study by image analysis system. Three main parameters, i.e., moisture content and its salinity, salt content and water-table level are exhibiting themselves as different colours in the coloured images. The approach described herein is recommended to be applied along the Red Sea coasts and other similar areas in order to present a preliminary but precisely identification of sabkha environments utilizing remote sensing techniques.
