Abstract: Highway planning is a complex task with many challenges since the interaction of this very long structure with rivers, streams and other structures on riverbanks is inevitable. Highway crossings design poses a special challenge to experts and requires detailed hydrological and hydraulic analyses to define the best solution. A generally accepted approach is to use state-of-the-art hydrological, 1D and 2D hydraulic models to better understand the interaction of the highway and rivers, and define the scope of works and measures that will minimize the effects of highway construction on the water regime. A very important first step in this modeling process is the hydrological analysis, which is needed to define different flood scenarios. This paper presents the hydrograph computation methodology, which includes the application of the coupled hydrological model HEC-HMS and the hydraulic model 1D HEC-RAS. The methodology can be used to create many scenarios where a large number of parameters (precipitation, soil moisture, etc.) are varied on the large basin area, delineated into many subbasins. The paper also presents the results of the methodology applied for the Morava Corridor design.
