ETALEMENT URBAIN ET SON IMPACT SUR LES RESSOURCES EN EAU MOYENNANT LA TELEDETECTION ET LES SIG : CAS DU GRAND TUNIS
Journal Title: Larhyss Journal - Year 2016, Vol 28, Issue 28
Abstract
The main objective of this work is to study the effects of urbanization on water resources in the Great Tunis, who knows a huge problem of anarchic urban expansion. To highlight the spatial and temporal variation in urban areas the classification of satellite images was used for various periods (1987-2013) through remote sensing software. This classification demonstrate a twice increase of urban surface. Using hydrologic equation and Geographical Information System (GIS) runoff and infiltrated water quantities are calculated in Greater Tunis basin allowed us to estimate the impact of urban expansion. The application shows that urban expansion caused disturbances on groundwater and essentially changes in water characteristics such as flow, rates and quality and infiltration rates.
