This paper presents a two-dimensional hydrodynamic modeling of a part of an urban road which considers topography, distribution of inlet grates and crossroads with the goal of determining better design criteria for urban road drainage. Preferential flow indicates the spatial distribution and concentrations of the greatest amount of unit flow, allowing the internal alignment of the location of grates to be obtained. The analysis of scenarios includes the variation of the types of flow input, rainfall intensity and distance between grates. This analysis is complemented by the inclusion of runoff hazard thresholds for pedestrians. The results show the particular behaviors of the flow over the road which is the input that determines the basic criterion for the distance between grates, based on a decision that balances hydraulic, risk and economic criteria.

Keywords : grate inlet; Iber; pedestrian stability; urban drainage; 2D modeling.
