- Two-dimensional hydrodynamic analysis of surface drainage on an urban road Manuel Cárdenas-Quintero Luis Fernando Carvajal-Serna Ramiro Marbello-Pérez Ingeniería Iber Grate inlet 2D modeling urban drainage pedestrian stability 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. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49663345012 https://www.redalyc.org/journal/496/49663345012/ https://www.redalyc.org/journal/496/49663345012/html/ https://www.redalyc.org/journal/496/49663345012/49663345012.epub https://www.redalyc.org/journal/496/49663345012/movil 10.15446/dyna.v86n211.79524 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.211 Vol.86
