Automated design flood estimation for highway drainage

Effective surface drainage is crucial for the strength and longevity of pavements, as water damage has been a known issue for centuries. Recent studies, including surveys of various transportation infrastructures globally, highlight the critical need for proper drainage, revealing that up to 90% of culvert failures result from hydrological issues. A meticulous analysis of hydrological data is essential to accurately estimate peak discharge, preventing severe pavement deterioration, particularly in regions like India's northern plains, where soft soils and uneven topography exacerbate the problem.
