“…Grassed swales and other vegetative controls, which can remove an average of 69, 46, and 56% of the total loads of total suspended solid (TSS), total phosphorus (TP), and total nitrogen (TN), respectively, have often been mentioned as vital components of any integrated stormwater management programs (Deletic & Fletcher, 2006). Infiltration trenches are used for a single block application, which can be implemented at the ground surface to intercept overland flow and show a higher ability in runoff reduction for small storm events (Maniquiz-Redillas, Geronimo, & Kim, 2014). The hydrological performance of LIDs varies significantly in various precipitation (Qin, Li, & Fu, 2013).…”

The pressures on water system are increasing in cities. Rapid urbanisation caused by booming population leads to more impervious area and less infiltration, with the consequence of larger runoff volume and higher flood risk. Launched in 2014, the low impact development (LID), an important part of Sponge City in China initiative, invests in projects that aim to restore the water cycle in the urban area. A comprehensive understanding of the performance of LID measures at watershed scale under different rainfall scenarios and life cycle costs is necessary. The objectives of this study are to assess the hydrological performance and to identify the optimal LID design by using SWMM model and life cycle cost (LCC) method. This study found that LID practices, including bioretention, grass swale, and permeable pavement, showed good performance on urban storm mitigation at watershed scale under different rainfall scenarios. Furthermore, the rates of surface runoff reduction were largely insusceptible to the change of rainfall volume and duration. Regarding the cost-effectiveness, the priority was grass swale > bioretention > permeable pavement in the study area. The optimal LID scenario was the combination of these three types of LID. The proposed approach can help the decision-makers to determine the preferable LID plan suitable for the local communities.

“…These technologies may include one or more pretreatment units to more efficiently remove sediment-related pollutants from stormwater, to dissipate the incoming runoff energy, and to facilitate sustainable maintenance [11,12]. The pretreatment unit removes particles, solids, and floating materials before the stormwater flows into the main system.…”

“…Multiple studies on pretreatment at NPS management facilities have evaluated the efficiency of pretreatment units, especially the effect of a pretreatment unit's sedimentation function. Maniquiz et al reported the relationship between surface area (SA) and storage volume (SV) of the pretreatment section based on field experiments conducted under various rainfall conditions [12]. The research revealed that the storage volume ratio could determine the treatment capacity of stormwater runoff and sediment and also affect maintenance frequency, such as sediment dredging.…”

Non-point source (NPS) pollution is one of the primary sources of contamination in aquatic systems, such as rivers and lakes. Various techniques and devices, including low impact development (LID) and best management practice (BMP) devices, can reduce NPS pollution. These devices are installed with pretreatment units to remove NPS pollutants more efficiently and to facilitate maintenance. In this study, suspended solids (SS) and particle size distributions (PSD) were investigated in a pilot-scale facility to determine the effect of various pretreatment unit types and inflows on SS removal. We found that the efficiency of SS concentration and particulate matter removal changed significantly (p < 0.05) based on the aspect ratio of the pretreatment unit. Three flow conditions were also tested (10, 15, and 20 m3/h); SS removal was most efficient at 15 m3/h. These findings can be applied to the design of NPS management facilities, which is expected to help increase the efficiency of new NPS facilities while reducing operating costs.

“…In addition, most of these substances are conveyed in particulate phase (Zgheib et al, ). Hence, presettling basins as a component of stormwater best management practice (BMP) technologies seem effective to intercept and trap particulate pollutants (Maniquiz‐Redillas et al, ). Stormwater detention basin is one of the most adopted BMPs in developed countries (Lawrence et al, ; Urbonas, ).…”

“…They are found in most cities in France, Canada, United States, and other European countries (Urbonas, ). Their effectiveness has already been proven to prevent flooding and trap pollutants by sedimentation, such as suspended solids, heavy metals, particulate nutrients, and hydrocarbons (e.g., Maniquiz‐Redillas et al, ; Marsalek & Marsalek, ). Stormwater detention basins are prone to accumulating large quantities of sediments that must be removed regularly in order to ensure their optimal trapping efficiency and to guarantee their storage capacities.…”

Stormwater detention basins are significant components for the sustainable management of urban stormwater, aiming to control stormwater quantity (prevent from flooding) and quality (trap particulate pollutants by settling). The design and management of such facilities need knowledge of the hydrodynamic characteristics and the sedimentation zones for cleaning purposes. Large-scale particle image velocimetry (LSPIV), mostly applied in riverine environments, has been proven as a low-cost, highly efficient, and convenient image-based methodology for surface velocity measurement. In this study, LSPIV technology is employed to investigate free surface velocity in a field stormwater detention basin. The method is first evaluated by comparing its results with those obtained by acoustic Doppler velocimeter at pilot scale. Then, the technique is applied to better understand the main flow field and to explain spatial sediment distribution within an extended stormwater detention basin. Results illustrate two main flow patterns, which are consistent with observations and preliminary simulated results. LSPIV-based free surface velocity field measurements can be used to evaluate numerical models and as a support to predict sediment deposition zones in stormwater detention basins and to help for their retrofit and management.
