Technical note: Rainfall water management using satellite imagery-example from Syria
Water management is one of the most important issues of the 21st century. Water resources must be better managed. Satellite imagery analysis are among the most advanced techniques for such an objective. Using space images several thematic maps can be established: tectonic, lineament and their density maps in relation to deformation factors; drainage and its density map in relation to the topographic factor, and facies maps in relation to the lithologic factor. Altogether these permit the construction of a recharge map which leads to the notion of the proposed mapping model. This allows for improved rainfall water management at the surface using dams and other methods such as lakes, trenches, etc., and in the subsurface in exploring ground water reservoirs and exploiting them by wells. In this study a mapping model based on satellite imagery was used to manage rainfall water in Sahel Akkar area, the southern part of the Syrian coastal chain. The results were checked in the field by geophysical measurement and water wells, which confirmed the obtained data. These positive results have proved the efficacy of this technique for management and exploiting of water resources. It is therefore an important tool in this domain.
