<![CDATA[This study explores the intricate relationship between hydrological processes, watershed management, and road infrastructure resilience, focusing on the impact of flooding on roads intersecting with streams in the River Nile State, Sudan. Located between 16.5°N to 18.5°N latitude and 33°E to 34°E longitude, this region, crucial to both ecological and economic aspects of the Nile River, faces significant challenges due to flooding. Utilizing precise Digital Elevation Models (DEMs) and advanced hydrological modeling techniques, the research aims to identify optimal solutions, such as overpass bridges, to mitigate flood risks. The total road length within the study area is quantified at 3572.279 kilometers, with stream orders categorized by length distribution: First Order at 2276.79 kilometers (50.7%), Second Order at 521.48 kilometers (11.6%), Third Order at 331.26 kilometers (7.4%), and Fourth Order at 1359.92 kilometers (30.3%). A notable flood event in 2020 disrupted approximately 120 meters of the Atbara - Shendi Road, revealing damage beyond initial expectations despite existing overpasses. This underscores the need for enhanced flood mitigation strategies and a reassessment of infrastructure resilience. The area where the flood caused the road cut had a watershed area of 214 square kilometers. The study identified 26 points where the watershed area is equal to or exceeds 214 square kilometers, indicating a higher risk of road disruption due to flooding. Enhanced scrutiny, potentially using high-resolution DEMs, is recommended for better assessment and management of these vulnerabilities. By integrating advanced DEM data and hydrological analysis, the study proposes tailored solutions to protect infrastructure while promoting sustainability and environmental stewardship.]]>
