Use of Remote Sensing Techniques in Hydrology to Mapping Water (Case
study: Algadarif Area).
Abstract
This study was conducted at Algadarif State Area, east of the Sudan
latitudes 12ᵒ 17/, longitudes 34ᵒ 36/ E, which aimed to build a database
of the morphometric of 26 properties from a 176 basin, this done through
analyzing a digital elevation model ( DEM ) by using a group of
geographical data systems programs, which integrated to result in a
large number of morphometric variances and measurements. They are
represented in the programs ArcMap 10.4.1 as basic programs and other
supportive programs like excel. The study was done for the purpose to
understand its hydrologic significances and consequently understanding
the water movement on the surface of the base. The study depended on the
data of the digital elevation model accurately 30 m in addition to a
group of maps and satellite images. Adoption of Algadarif State upon
automatic agriculture who leads to needing to know a lot about
conditions, nature and description runoff water for the rain to know the
different characteristics for basins to draw the water map of the State,
recognition of cadastral characteristics and formal properties, identify
the histological properties and water drainage network characteristics.
Arc gis was installed on a windows 10 computer and loaded the digital
elevation model for the experiment site from earth explorer, the DEM
file was only used. Work was done by Arc Hydro Tools within the Arc GIS.
