“…However, the FF 30 values for all the parameters studied were not correlated with the time of maximum rainfall intensity, which differs from the previous study. Li et al (2007) concluded that the maximum rainfall intensity appears earlier and would cause a more distinctive FF. The difference with our study was that the road with a high slope (10°) leads to higher runoff velocity and stronger flushing capacity to road; therefore, when the rainfall intensity is not large in the initial of rainfall, the first flush also occurred and the time of maximum rainfall intensity had less affect on the FF 30 .…”

This study investigates the quality of stormwater runoff from a driveway in the southwest mountainous urban area of Chongqing, China, from 2010 to 2011. The results showed that the mean concentrations of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) were 4.1, 2.4, and 2.2 times the grade V levels of the national surface water standard of China. The pollutant concentration peak preceded or synchronized with the rainfall intensity peak and occurred 10 min after the runoff started. The significant high pollutant concentration in the initial stage of the rainfall suggested that first flush control is necessary, especially for the most polluted constitutes, such as total suspended solids, COD, and TN. Three potential pollution sources were identified: the atmospheric dry and wet deposition (TN, NO 3 − -N, NH 4 + -N, and DCu), the road sediment and materials (total suspended solids, COD, and TP), and the vehicle emissions (DPb and DZn). Therefore, this study indicates that reductions in road sediments and material pollution and dry and wet deposition should be the priority factors for pollution control of road stormwater runoff in mountainous urban areas.

“…EMCs of various pollutants in surface runoff are shown in (Ballo et al, 2009;Che et al, 2003;Gromaire-Mertz et al, 1999;Li et al, 2007;Ren et al, 2008;Wang et al, 2013). For road runoff, EMCs of COD and TSS in the present study were 2-3 times higher than those in Beijing, Paris, and a German city.…”

“…In recent years, urban nonpoint source pollution has gradually become the major pollution source in water quality deterioration (Davis and Birch, 2009;Lee and Bang, 2000). There has been a number of studies on urban nonpoint source pollution for many cities throughout China (e.g., Che et al, 2003;Li et al, 2007;Ren et al, 2008), arousing widespread concern among scientists, environmentalists, government regulators, and the public in China. Currently, research of urban nonpoint source pollution focused on various land uses, including typical residential, commercial, industrial, road and roof areas (Clark et al, 2008;Lee et al, 2002;Luo et al, 2012), of which very few is concerning those close to factories.…”

“…The FF 30 from four rainfall events for a highly urbanized area in China, which had a drainage area of 115-218 ha, a percentage of urban area of 62.5-90.1%, and a rainfall depth of 6.3-57.8 mm, ranged from 0.189 to 0.614 (COD, NH 3 -N, TN, TP, SS, and BOD 5 ) (Ma et al, 2011). In addition, for an urban area with a catchment area of 480 ha, an impervious surfaces ratio of 85%, and mixed discharge of stormwater runoff and untreated wastewater, the FF 30 from 8 rainfall events was 52.2-72.1% for total SS (TSS), 53.0-65.3% for COD, 40.4-50.6% for TN, and 45.8-63.2% for TP [21].…”

Abstract:The dense highland field area in the upstream region of the Lake Soyang watershed is subject to excessive soil erosion during the wet season. In this study, stormwater runoff from the Lake Soyang watershed was monitored during four rainfall events at 10 locations throughout 2016. The maximum SS concentration at Naedongcheon, which is located in the upper part of the Soyang River, reached 4598 mg/L. The event mean concentration (EMC) of SS loads in Naedongcheon ranged from 82.2 mg/L to 926.3 mg/L. We found that, although the first flush events were usually concentrated in highly paved urban areas, a first flush occurred in the agricultural area of the dense highland field region. The first flush phenomenon was identified by a dimensionless cumulative runoff mass and volume curve (M(V) curve), and the intensity of the first flush was analyzed by the coefficient of the nonlinear regression model and the FF 30 and FF 25 values (the fraction of pollution load transported by the first 30% and 25% of runoff, respectively). Nonlinear regression models using the power function were applied to fit the M(V) curve, the FF 30 values were inversely proportional to the coefficient a of the regression model. A long-term seasonal trend decomposition for monthly turbidity and precipitation was performed for the Lake Soyang. Long-term turbidity trend was approximately coincident with the trend in long-term precipitation. In addition, the present status of the best management practices (BMPs) in the upper part of the Soyang River basin was investigated, and a survey of the management and operation of the BMPs was conducted for selected farmers.
