Detection Depth of Mosul Dam Reservoir by Using Image Processing Techniques

The remote sensing techniques can be used for more quantitative studies in water management and monitoring. This occurs when, these techniques are connected with GIS programs. In the current study, (ETM+) images have been used to estimate water depth of Mosul Dam's Reservoir that is located North of Iraq and specifically north of Mosul city (40 Km). By applying multispectral image processing techniques that are associate with GIS programs, through using of Matlab 7.5, ERDAS 8.4, Arc View 3.2 and Glober Mapper 7 programs. When applied the algorithm of the processing showed that the band 1 and band 5 are suitable for this study, and the (.ras) format for image have increase of pixel dimension and as well the pattern distribution of pixel intensity give more details at low gray levels, and the value of threshold 0.985 are very necessary to success of entropy filter work. Results of application of linear model's were shown as map of depth distribution started from 0 to 80 meters. Where the shallow and moderate depth (>60m ) were take up south part's of reservoir, while the deep water (<60m) take up middle and upper part's of Mosul reservoir.
