“…Due to the high variability in pollutant concentrations throughout a given stormwater runoff event, the EMC was used as a measure to compare the pollution between rain events (Sansalone and Buchberger 1997;Lee and Bang 2000).…”

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.

“…In Naedongcheon (the upper part of the Mandae area) and Jungjohangcheon (the upper part of the Jaun area), the first flush is indicated by the SS, TP and BOD values. Although the first flush mostly occurs during storm events in highly paved watersheds in urban and mixed land use areas [14,17,23], the first flush phenomenon was identified in the agricultural region of this study, where excessive soil erosion occurs. The shape of the M(V) curve of the rainfall event occurring on 1-3 October in Jungjohangcheon is concave (Figure 6) because the rainfall intensity was high at the final stage of rainfall.…”

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.

“…Using this platform, Rainwater+ is able to provide instant feedback based on CAD models throughout the entire design process. Rainwater+ is positioned to address rainwater management issues of site less than 1 km2 -the relatively small and integrated drainage basins in urban built-up regions that are vulnerable to severe urban flood risks (Lee andHeaney 2003, Dietz andClausen 2008).…”

“…Rapid urban expansion and the increased impervious surfaces associated with city development have consistently shown to result in degraded aquatic ecosystems (Carter and Jackson, 2007;Hsieh and Davis, 2005;Lee and Bang, 2000;Miltner et al, 2004). The replacement of vegetated areas that provide rainwater interception and storage, often results in an increase in the rate and volume of stormwater runoff (Kim et al, 2003;Mansell, 2003;Whitford et al, 2001).…”

For stormwater management, Low Impact Development (LID) practices provide more sustainable solutions than traditional piping and storm ponds. However, to be effective, LID practices must be integrated into planning at the beginning of the design process; yet architects and related design professionals making decisions early in the design process are not equipped to consider runoff calculations given their current tools. In response to this dilemma, we have developed an open source stormwater runoff evaluation and management tool: Rainwater+. It is seamlessly integrated into computer-aided design (CAD) software to receive instant estimate on the stormwater runoff volume of architecture and landscape designs. Designers can thereby develop appropriate rainwater management strategies for the project-based on local precipitation data, specific standards, site conditions and economic considerations. We employed Rainwater+ to conduct two case studies illustrating the importance of considering storm water runoff in the early design stage. The first case study showed the importance of integrating rainwater management into design modeling software for the reason that the specific site condition is critical for determining LID practice. The second case study demonstrated the need of visualizing runoff flow direction in assisting the placement of LID practices at proper locations when the terrain is of great complexity.
