“…This amplifies, therefore, the need to take the intrinsic rainfall variability into account in design calculations (Guo and Urbonas, 1996;Vaes and Berlamont, 2001;Calabrò and Viviani, 2006). For example, Urbonas (1996, 2002) estimated tank volume by means of a runoff capture curve (that relates the capture flow percentage of a stormwater tank to the ratio between volume and average rainfall depth), using 30-to 40-year continuous rainfall data recorded in seven metropolitan areas in the United States.…”

Pollution induced by runoff on receivers is an environmental problem deserving of much attention, especially over the past few years. The structural facilities most commonly used for first flush pollution impact reduction include sewer overflows and stormwater tanks. Nevertheless, their efficiency is a current research topic and the design criteria are not completely consolidated.Based on extensive numerical simulations from 45 rain gauges located in Campania (southern Italy), two recent studies show that the performance of sewer overflows and offline stormwater tanks in reducing stormwater pollution can be reliably estimated without referring to rainfall data. Although rainfall dependency is generally negligible, it is more marked for some rainfall patterns.On the basis of that observation, this paper proposes a simplified approach to estimate pollution reduction when sewer overflows or stormwater tanks are used, correlating their efficiency to the average rainfall per wet day, which is usually easy to calculate.Analysis shows RÉ SUMÉLa pollution induite par les eaux pluviales sur les milieux aquatiques récepteurs devient un problème environnemental majeur. Les ouvrages le plus généralement utilisées pour la réduction de l'impact de pollution des eaux pluviales de première chasse sont le débordement de l'égout et les réservoirs d'eaux pluviales. Néanmoins leur efficacité est de nos jours un sujet de recherche et les critères de conception ne sont pas consolidés complètement.Au moyen des simulations numériques vastes se référant à 45 pluviomètres situés dans la Région de Campania (Italie), deux articles récents ont montré que l'abattement de la pollution du au débordement de l'égout ou aux bassins de rétention peut être valablement évalué sans se référer aux données de précipitations. Bien que la dépendance à l'évènement pluvieux soit généralement négligeable, elle est cependant marquée pour quelques schémas de précipitations.Sur la base de cette observation, dans le présent article on propose une approche simplifiée pour évaluer la réduction de pollution quand l'égout déborde ou quand les bassins de rétention d'eaux pluviales se remplissent, en corrélant leur efficacité à la précipitation moyenne par jour humide, ce qui est habituellement facile à calculer.L'analyse a montré un bon accord entre des valeurs évaluées selon les résultats de l'approche proposée et ceux obtenus par des simulations continues, avec un écart maximal d'environ 0.05.

“…Detention basins are considered an effective tool for stormwater quantity and quality control in many urban areas and there are different views on the selection of optimum detention volume (Guo, 1999). For size selection of small basins, the volume-based methods such as the Federal Aviation Administration's method are used for stormwater detention designs and the capture volume method for stormwater retention designs (Guo and Urbonas, 1996).…”

A new sub-surface detention/retention system, called the StorageeInfiltration Block (SIB) system, has been developed for the purposes of reduction of volume and flow rate of stormwater runoff and recharging groundwater. This paper presents a method in the determination of the maximum storage volume and maximum surface area required for the system. The method is based on the determination of the maximum difference between the volume of stormwater runoff entering the system and the volume released from the system by the infiltration process. The stormwater runoff inflow volume is determined using the Rational formula. The rainfall intensities were calculated based on the rainfall IDF relationships published by the Department of Irrigation and Drainage, Malaysia. An example is also included in this paper to demonstrate the calculation procedure. The example shows that the prediction of the maximum storage volume using this method is fast and accurate. Ó

“…Conversely, nearly 95 % of pollutant runoff from urban areas is produced from events smaller than a 2 yr storm (Guo and Urbonas, 1996;Pitt, 1999;NRC, 2009). It is well recognized that the best way to resolve this pollution problem is to implement controls as close to the source of runoff generation as possible (Debo and Reese, 2003;WEF-ASCE, 2012).…”

Abstract. Urban stormwater runoff quantity and quality are strongly dependent upon catchment properties. Models are used to simulate the runoff characteristics, but the output from a stormwater management model is dependent on how the catchment area is subdivided and represented as spatial elements. For green infrastructure modeling, we suggest a discretization method 10 that distinguishes directly connected impervious area from the total impervious area. Pervious buffers, which receive runoff from upgradient impervious areas should also be identified as a separate subset of the entire pervious area. This separation provides an improved model representation of the runoff process. With these criteria in mind, an approach to spatial discretization for projects using the U.S. Environmental Protection Agency's Storm Water Management Model is demonstrated for the Shayler Crossing watershed, a well-monitored, residential suburban area occupying 100 ha, east of Cincinnati, Ohio. 15The model relies on a highly resolved spatial database of urban land cover, stormwater drainage features, and topography. To validate the spatial discretization approach, six different representations were evaluated with eight 24 h synthetic storms. With minimal calibration effort, the suggested approach out-performed other options and was highly correlated with the observed values for a two month continuous simulation period (Nash-Sutcliffe coefficient = 0.852; R 2 = 0.871). The approach accommodates the distribution of runoff contributions from different spatial components and flow pathways that would impact 20 green infrastructure performance. We found that when all subcatchments are discretized with the same land cover types, instead of using an j × k array of calibration parameters, based on j subcatchments and k parameters per subcatchment, the values used for the parameter set for one subcatchment can be applied in all cases (i.e., just k parameters). This approach not only reduces the number of modeled parameters, but also is scale-independent and can be applied directly to a larger watershed without further amendment. Finally, with a few model adjustments, we show how the simulated stream hydrograph can be separated 25 into the relative contributions from different land cover types and subsurface sources, adding insight to the potential effectiveness of the planned green infrastructure scenarios at the watershed scale.
