- Abstract
The present study fits with an important step into the country development and its hydrous capacity valorization. For that purpose, an evaluation study of surface water quality of Tafna catchment's basin was accomplished. Within the framework of this study, we propose to elaborate a water surface quality maps based on the physic-chemical quality calculation Global Quality Index (GQI). Considering the various indexes and the important amount of data to be handled, we think that it is more judicious to elaborate a computerized program in order to perform an automatic and rapid calculation of different indexes in the time. With the help of the Geographical Information System (GIS) we created a quality maps in accordance with Quality Indexes. The studied has revealed a bad water quality in the whole basin. The registered pollution is of organic type. The main source of water pollution comes from the industrial plants located in the basin.
