“…This research follows the processes and equations provided by Guo et al [40] and UDFCD [41] to estimate the drain inlet capacity. Guo et al [40] has provided a series of equations applied to estimate discharge capacity of sump type inlets. A sump inlet is any inlet that is located at the lowest point of a drainage area [41].…”

“…The operation of an inlet is subject to the clogging due to urban debris that can obstruct the drainage system. It is noted the the equations provided by [40] do not consider clogging effect. In real situation, all the inlets are affected by clogging [41], and hence, a clogging factor should be applied to adjust the inlet capacity.…”

“…A clogging factor quantifies the effect of obstruction on discharge capacity ranging between 0 (no clogging) and 1(fully clogged) [41]. In this research, the equations of [40] are modified to include clogging factor estimated from [41] for effective discharge capacity of the inlets.…”

“…The Blacklot drain inlet has equal length combination of grate and curb-opening with 116 inches (294.68 cm) length, 18 inches (45.72 cm) width, and 6 inches (15.24 cm) of curb-opening height. This inlet is also a combination type 16 as each segment consists of a vane grate and a curb opening [40]. The following paragraphs describe the specifics of the GIS-based framework for this area.…”

This research aims to develop a framework using the Geographic Information System (GIS) to perform modeling and mapping of flood spatiotemporal variation in urban micro-watersheds. The GIS-framework includes a workflow of several methods and processes including delineation of urban watershed, generation of runoff hydrographs, and time series mapping of inundation depths and flood extent. This framework is tested in areas previously known to have experienced flooding at the University of Nevada, Las Vegas main campus, including Black Parking Lot (Blacklot) and East Mall. Calibration is performed by varying Digital Elevation Model (DEM) resolution, rainfall temporal resolution, and clogging factor whereas validation is performed using flood information from news reports and photographs. The testing at the Blacklot site resulted in calibration at 5 m DEM resolution and clogging factor of 0.83. The flood model resulted in an error of 24% between the estimated (26 inches/66 cm) and actual (34 inches/86.36 cm) flood depths. The estimated flood extents are consistent with the reported conditions and observed watermarks in the area. The flood beginning time estimated from the model is also consistent with the news reports. The testing at East Mall site also shows consistent results. The GIS framework provides spatiotemporal maps of flood inundation for visualization of flood dynamics. This research provides insight into flood modeling and mapping for a storm drain inlet-based watershed.

“…There are several studies that have developed formulations to represent the process of inlet flow into the grate inlet. In general, the formulations are subject to efficiency or they are orifice or weir equations [15][16][17][18]. Also, physical experimentations have been carried out with different shapes and geometries of cross bars [19,20].…”

Se presenta la modelación hidrodinámica 2D de un tramo de una vía urbana considerando las características de topografía, distribución de sumideros y cruces de vías, con el objeto de definir mejores criterios de diseño del drenaje vial urbano. El flujo preferente indica la distribución espacial donde se concentra la mayor cantidad de caudal unitario, el cual permite determinar un alineamiento interno para la ubicación de sumideros. Se evalúan diferentes escenarios de análisis que incluye la variación de los tipos de entrada de caudal, la intensidad de lluvia y la distancia entre sumideros, complementados con la inclusión de umbrales de peligrosidad de la escorrentía para los peatones. De los escenarios simulados se obtienen los comportamientos particulares del flujo sobre la vía y se define un criterio básico para la longitud de separación entre sumideros con base en un equilibrio entre criterios hidráulicos, de riesgo y económicos.

Due to the high population density and economic property in urban environments, urban flooding can result in substantial economic losses. However, accurate urban flood modeling and assessing the associated damages are challenging due to complex urban layouts and rugged topography. Furthermore, the rapid development of urban underground spaces has introduced additional complexities. To address the demanding need for accurate flood modeling and damage assessment in cities, a fine‐scale flood damage assessment method was proposed in this study, based on the 1D/2D coupled hydrodynamic model, which can not only assess the flood damage on the ground surface but also evaluate the flood loss in underground spaces. Taking the Gangxi drainage area in Wuhan City, China as a case, this study extensively discussed the flood inundation processes on the ground surface as well as in the buildings and underground spaces, under different rainfall scenarios with the return period ranging from 2 to 200 years. Based on the high spatial‐temporal hydrodynamic simulations, the flood damage degrees were evaluated for the buildings and underground spaces with different industry types. The results indicated that the inundation of buildings and underground spaces in densely built cities cannot be neglected in urban flood modeling. Buildings with public service attributes can have a higher flood damage degree, as compared with other types of buildings and underground spaces.
