  • Assessing the Effects of Urban Landscape Area and Pattern Change on Flood Events in Qinhuai River Basin, China
    Item type: Journal Article

    Urbanization significantly affects hydrological processes, but the influence level of urban landscape area change (ULAC) on flood magnitude has not been quantified, the response laws of floods with different characteristics to ULAC still needs further discussion, and the effects of urban landscape structure and shape on flooding have not been illustrated. This paper used a Markov chain and cellular automata (CA-Markov) model, the Hydrologic Engineering Center's Hydrologic Modeling System (HEC-HMS) model, and the regression analysis method to assess the effects of ULAC on flooding. The Qinhuai River Basin (QRB) was selected to conduct the study. The results showed that (1) for minor, medium, and major flood groups, the statistical ranges of the linear curve [the relationship between flood volume (Qv) relative change and urbanization] slopes were 0.46-3.44, 0.74-1.82, and 0.24-0.76, respectively, whereas for peak flow (Qp) they were 0.8-3.27, 0.34-1.61, and 0.09-0.12, respectively; (2) the influence degree of ULAC on flood processes is gradually weakened with flood evolution; (3) for double-peak floods, the increase of the urban landscape area can significantly increase the Qp in the early stage and lead to earlier appearance of Qp, but for single-peak floods, the influence on peak time is not significant; and (4) urban landscape structure is more important than shape in terms of flood protection. © 2020 American Society of Civil Engineers.

  • Evaluation of Stormwater Mitigation Performance with LID Infrastructures, In-Sewer Space, and Real-Time Control Strategies
    Item type: Journal Article

    Because low-impact development (LID) infrastructures are effective in capturing and utilizing urban stormwater runoff, real-time control (RTC) strategies can be viewed as soft infrastructures, offering an additional suite of opportunities to improve the stormwater drainage system performance. However, there is a paucity of analyses that disentangle the contributing sources of performance enhancement in these joint hard–soft stormwater infrastructures. This study evaluated the stormwater system performance with integrated LID infrastructures, in-sewer storage capacity, and RTC strategies. Our results showed that LID infrastructures play a major role in mitigating the flow peaks and high volumes, whereas adding RTC to the storage unit and in-sewer flow control mostly improves the performance under relatively small rainfall events, e.g., those with a 3-year return period. The critical contribution of RTC is realized by utilizing storage units as much as possible during the rainfall event. A downstream storage unit that is too close to the outfall may not be suitable for RTC application together with in-sewer capacity utilization. In the present case, the combination of a midstream storage unit and upstream control site at branch pipes worked better than those at other locations. The results suggest that the integration of LID and RTC on a simulation-system level can enhance the reduction of the peak runoff and total discharged volume only if the storage site and control locations are selected carefully.
