Apport de la télédétection à l’analyse des affects de changement climatique sur les ressources en eau De la région de Tizi-Ouzou.

Abstract

The work of this dissertation introduced by a generality by presenting the sector of the study area and by determining the geography, geology, hydrogeology and the hydrographic network contributed by figures and images. Subsequently a description of the study region was made, with an analysis of its remote sensing context. Based on the data obtained, an analysis campaign was carried out in different dates, from the year 2016 until July 2021 in the high water period and the low water period in order to extract the effects report. Change on the Taksebt dam. The remote sensing study was done by processing sentinel-2 images of the study area after uploading them to the Copernicus site. This allowed defining the ratio of the variation and change of the flow and the surface of the dam during the given time.
