Abstract
The flood risk mapping documents for pilot areas along the Blue Nile River in Sudan presented here are the results of multi-disciplinary study that include products from topographic data collection and surveying, terrain modeling, hydrologic analysis, hydraulic modeling and analysis, flood hazard mapping, economic data collection and damage analysis, and vulnerability and risk assessment.
The pilot areas considered were:
* Khartoum City, covering part of Khartoum City along the Blue Nile and the proposed development area at Soba
* Hasahisa and Wad Medani at the River Rahad junction
* Singa City
* Roseires Dam
The maps developed as a result of this study convey the most basic information about the general vicinity in which flooding can be expected with varying frequencies. Local communities can make immediate use of these maps to identify areas of focus for flood protection, preparedness, warning, and future development guidelines. A flood extent map can be a valuable aid in communicating flood risk to local populations as part of education and outreach programs to encourage appropriate response.
