“…where i(t a ) and i(t b ) are the storm intensity (mm/min) after and before the peak time point respectively; the parameter r refers to the time-to-peak factor. According to previous studies [37,38], this value ranges from 0-1 of the storm duration, and a reasonable range for r is 0.3-0.5. Short of any other information available, a value of 0.5 was chosen in this study.…”

An investigation into the effectiveness of bioretention cells (BCs) under potential climatic changes was conducted using representative concentration pathways. A case study of Guangzhou showed changes in peak runoff in climate change scenarios, with obvious growth in RCP8.5 and slight growth in RCP2.6. The performance of BCs on multiple parameters, including reduction of runoff volume, peak runoff, and first flush, were examined in different design storms using a hydrology model (SWMM). The effectiveness of BCs varied non-linearly with scale. Their performance fell by varying amounts in the various scenarios. BCs could provide sufficient effects in response to short-return-period and short-duration storms, but the performance of BCs decreased with heavy storms, especially considering climate change. Hence, BCs cannot replace grey infrastructure but should be integrated with them. The method developed in this study could be useful in the planning and design of low impact development in view of future climate changes.

“…Chicago hyetograph method (Keifer and Chu, 1957) was used for rainstorm design (Qin et al, 2013). The ratio of time to peak point r was set as 0.4 (Jia et al, 2014;Silveira, 2016). Four return periods (2-, 10-, 50-and 100-year) and three rainfall durations (2-4-and 6-hour) were considered.…”

Low impact development technologies (LIDs) have been reported as alternatives to mitigate urban water-related hazards, particularly for urban flooding. However, the effectiveness of LIDs on flood mitigation is still not well understood. This study assessed the mitigation extent of urban flooding by LIDs for retrofitting an urbanized area at a feasible level using a hydrological model. A range of storms with different rainfall durations and amounts from intensity-duration-frequency curves were used to evaluate the hydrological performances of LIDs. The results indicated that LIDs were effective alternatives to mitigate urban flooding in the urbanized area. Surface runoff and peak flow decreased by 18.6-59.2% and 8-71.4%, respectively. However, the flood mitigation performance decreased markedly with the increase of rainfall amount. Although LIDs were less effective in flood mitigation during shorter and heavier storms, the performance was better with the increase of rainfall duration. This research provides an insight into flood reduction capabilities of LIDs under different rainfall characteristics for retrofitting built up areas, which is useful for urban storm management.

“…Considering increased water demand along with water shortage, surface runoff can be managed to be used for recreational and outdoor water uses sometimes after partial purification (Jia et al, 2014). Therefore, runoff quality and quantity control and management in urban areas are of great importance.…”
