“…In addition, even in cases where the sewer network is known in detail, comprehensive data on inlet locations are often missing or incomplete [145]. For this reason, many studies have focused on the numerical and experimental hydraulic characterization of drain inlets [150][151][152][153][154][155][156][157][158][159], as well as on the sensitivity of model results to the physical characteristics and location of inlets [97,145]. Inlet clogging due to a lack of maintenance and clearance has also been recognized as a major problem, indeed, one that can cause more flooding incidents than storm-sewer overloading does, especially in flat urban areas, leading to local flooding before the designed hydraulic capacity of the sewer network is reached [102,144,160].…”

The modelling and management of flood risk in urban areas are increasingly recognized as global challenges. The complexity of these issues is a consequence of the existence of several distinct sources of risk, including not only fluvial, tidal and coastal flooding, but also exposure to urban runoff and local drainage failure, and the various management strategies that can be proposed. The high degree of vulnerability that characterizes such areas is expected to increase in the future due to the effects of climate change, the growth of the population living in cities, and urban densification. An increasing awareness of the socio-economic losses and environmental impact of urban flooding is clearly reflected in the recent expansion of the number of studies related to the modelling and management of urban flooding, sometimes within the framework of adaptation to climate change. The goal of the current paper is to provide a general review of the recent advances in flood-risk modelling and management, while also exploring future perspectives in these fields of research.

“…Este modelo resuelve las ecuaciones bidimensionales de flujo en lámina libre y, además, incorpora procesos hidrológicos (precipitación, infiltración, percolación, evaporación, flujo subsuperficial, etc. ), lo que le confiere la capacidad de realizar modelización distribuida hidrológica-hidráulica de forma acoplada, tanto a nivel de cuenca (Cea y Bladé, 2015;Fraga et al, 2013Fraga et al, , 2020Fraga et al, , 2021Sanz-Ramos et al, 2018, 2020a) como a nivel de ciudad o calzada (Sanz-Ramos et al, 2020c;Sañudo et al, 2020;Aranda et al, 2021). Las dos zonas de estudio analizadas representan tramos o calles completas de la ciudad de Barcelona con características geométricas, dimensiones y niveles de riesgo diferentes (Russo et al, 2019;Ortiz et al, 2020).…”

Los Sistemas Urbanos de Drenaje Sostenible (SUDS) suponen una alternativa válida para dar solución a diversos problemas del drenaje urbano. Su aplicación, generalmente de carácter puntual, es limitada y puede no ser efectiva para dar solución al previsible incremento de las intensidades máximas de precipitación asociadas al Cambio Climático. El presente estudio analiza, en situación actual y con proyecciones del Cambio Climático, los potenciales beneficios de aplicar pavimento permeable en carriles bici, convirtiéndose en elementos de captación lineal, continua y difusa (“SUDS-lineales”). Mediante el uso de un modelo numérico hidráulico-hidrológico acoplado que incorpora la capacidad de infiltración de un pavimento permeable, y tomando como ejemplo dos zonas de la ciudad de Barcelona con distinta peligrosidad por inundaciones pluviales, se evaluó el comportamiento global de los SUDS-lineales considerando escenarios de precipitación actual y los potenciales efectos del Cambio Climático. Los resultados numéricos mostraron una reducción potencial del 90% de la escorrentía.

Urban pluvial floods can be produced or exacerbated by an insufficient density of inlets or by their poor hydraulic efficiency. Therefore, proper consideration of the hydraulic performance of inlets is essential to guarantee the correct functioning of urban drainage systems during heavy storm events. Recent advances in computational analysis in the field of hydrodynamics modelling allow the use of the well-known concept of dual drainage for design and planning purposes by simulating flow transfers between the surface layer (streets) and underground layers (sewers) through a proper hydraulic characterisation of inlet efficiency. Powerful commercial software packages allow simulations of flow transfer and use different approaches and formulas. Many of these approaches include the possibility of treating a sewer inlet as an orifice. In this context, this paper presents a methodology to obtain orifice discharge coefficients for three inlets previously tested at the hydraulics laboratory of the Technical University of Catalonia. Discharge coefficients of 0.18–0.58 were obtained for Froude numbers of 1.12–4.40, quite far from the usual recommended values. The proposed procedure can also be applied to non-tested grates.
