Abstract
The establishment of water courses between the rivers in the study area would reduce Sudan Nile water share surplus and water can be used for pumping and flood irrigation agriculture. This will improve local people standard of living and provide good chances for more people to settle in the area. Excellent contribution to desertification combating can be made as well as a reduction in negative environmental impacts by the increase of the green areas. The effort made in this paper investigated the potentialities and challenges of creating water courses between rivers in north Sudan area. The topographical and hydrological models of the study area were created using its free of charge SRTM90 digital elevation model and QGIS and GRASS application programs. Two water courses were proposed in the area and their geometrical characteristics were discussed. Water course 1 starts from the White Nile river in the White Nile state and ends at the river Nile meandering leg in the northern state with a total length of 415.454 km. Water course 2, starts from the Nile river in the Nile state and ends at the Nile river in the northern state, with a total length of 327.285 km. The investigation revealed the potentialities and highlighted the challenges of creating water courses between rivers in the area. It demonstrated the important role of the open data and application programs in improving local people standards of living, providing chances for more people to settle in and combating the desertification in the area.
Highlights
The river Nile course, Sudan in Abu Hamed area is characterized by a very long meandering section that approximately, starts from latitude 15° N, passing latitude 19.5° N and coming back to latitude 18° N, with a meandering longitude span of 1.5° (158 km approximately), (Fig. 1)
The water could flow from south to north in the valleys zone by natural gravity. It is very clear from the spatial distribution of the topographical zones in the potential area that, crossing the water divide zone is unavoidable for conveying water from the White Nile/Nile through the valleys zone (Fig. 3)
A considerable effort was made by the author in exploring the topographical model, the hydrological model and their integration model using the zoom in /zoom out facility available in the adopted application programs
Summary
The river Nile course, Sudan in Abu Hamed area is characterized by a very long meandering section that approximately, starts from latitude 15° N, passing latitude 19.5° N and coming back to latitude 18° N, with a meandering longitude span of 1.5° (158 km approximately), (Fig. 1). This investigation addressed the potentialities and challenges of creating such water courses in the area, using the open data and application programs sources. The topographical model of the area was formed using its free of charge SRTM90 digital elevation model, QGIS and GRASS application programs This topographical model of the area was used to categorize the area into different topographical zones to facilitate the further analysis stages and limit the investigation effort to the potential parts of the study area. The challenges as well as the benefits of creating these water courses were highlighted
