Location analysis of the collection of the waters of Galal Badra using geographical information system (GIS)

Abstract

Geographical Information Systems have recently become important advanced means of dealing with data in various scientific studies ,most importantly the hydrological studies .This is because these systems offer meticulous mechanical methods of analyzing location data and connect them with descriptive data helping as in studying the morphometric features of water drain nets by using advanced mechanisms and building a data base with morphometric variables based on advanced data sources such as satellite images and digital elevation models(DEM) ,by which location analyses can be conducted to arrive at varied, quick and precise results, compared to traditional methods .These location information systems ,which follow means of measurement ,analysis and interpretation, can help predict the locations of water basins and offer suggestions and solutions that can enhance future development plans .The morphometric features are generally considered quantitative geomorphological features .These are analytic methods that tackle the phenomena of earth surface by using data collected from contour maps, air images ,satellite images and field studies such as DEM .The analysis of the morphometric features to construct a location data base for Badra Galal valley and to draw the water drain system for the basin as a natural morphometric phenomenon plays a role to determine the use of earth in the water collection process, to benefit from it during the times of dryness; it can also be used to construct a sinking dam in the valley stream and preserve the waters for the purposes of processing the sediments moving through the valley stream and their effect on the sinking dam ,as well as studying the water drain levels during the rainstorms of the wet season.
