WillemsThe Nile River is considered as the major renewable freshwater supply for Egypt. TheRosetta branch is one of its two main tributaries, and it is the main source of water forthe northern part of Egypt. The branch is under the influence of three different sourcesof pollution which affect its water quality characteristics. The aim of this study is to useLandsat Enhanced Thematic Mapper Plus (ETM+) imageries as an efficient way forestimating water quality parameters concentrations chlorophyll-a (Chl-a), TotalSuspended Sediments (TSS), and Temperature. Such data can be use to help inmonitoring water quality situation along the branch. Therefore, two Landsat (ETM+)images for the branch were collected in February and December, 2001. The imageswere processed using ENVI (Environment for Visualizing Images) program to derivewater quality parameters for the Rosetta Branch. 40 samples were taken along thebranch to study the trend of parameters concentrations. The results were comparedwith other correlated parameters gotten from MIKE-11 River Modeling software and 5monitoring points along the branch during February, 2001. Results show that usingLandsat-7 images data could be efficient and affordable in economic point of view todetermine water quality parameters but in-situ data should be obtained and examinethe used algorithms to derive the most appropriate algorithm.- 13 -
