Abstract : The application of recently developed information techniques has received great attention in the last decade analyzing various hydrological processes. The main objective of this research is to couple the remote :1 sensing techniques with pydrologic model approach in order to estimate peak discharge on small size catchments within Wadi Itwad located in the southwestern part of the Kingdom of Saudi Arabia. Information on the lithology, drainage pattern, frequency and spatial distribution of the fractures for the small basins are collected, processed and presented as plates and figures. They are obtained through the study of False Color Composite (FCC) and ratio images of the Landsat Thematic mapper (TM). The peak discharges for the small catchments are estimated through the application of hydrological model (TR~55) and the results are compared with the outputs obtained from the application of rational formula which is the method commonly applied in Hydrology. On the other hand, the peak discharges for the medium size catchments are determined by Creager Formula and Point Frequency Distribution Functions. The results show that processed Landsat Thematic mapper data in colored form is highly appropriate for digitizing the information required as input parameters for hydrological model application. The model parameters represent non-parametric information in terms ofcurve numbers which are the digitized form of lithology, land use and soil formation.
