“…Liao et al (2013) analyze the hydrological effects and also life cycle costs of bioretention, infiltration trench, porous pavement, rain barrels, and green swale in different design storms in Shanghai. However, most research focuses on relatively large scale design optimization, and at most examines the impacts of total LID coverage percentage and LID depth (Trinh and Chui, 2013;Qin et al, 2013;Palanisamy and Chui, 2015;Jia et al, 2015b). There is very limited information or guideline regarding the design of specific LID practice (i.e., optimal depth, width and length) at a household or business scale (e.g.…”

“…These studies are potentially defining their own research niches, and include using treatment trains (Jia, Wang et al, 2015), retrofitting traditional urban stormwater infrastructure with LID (Palanisamy and Chui, 2015), and using mycofiltration for treating stormwater (Taylor et al, 2015). Jia, Wang et al (2015) monitored a LID treatment train that included grass swales, a buffer strip, two infiltration pits, and a constructed wetland.…”

The following review presents a synthesis of 181 journal articles published during 2015 that represent progress toward better characterizing, controlling, and treating urban stormwater runoff. The review is structured by general topical areas related to (1) stormwater quality and quantity characterization; (2) engineered stormwater control and treatment practices, including erosion and sediment control, stormwater ponds, constructed stormwater wetlands, bioretention, permeable pavement, greenroofs, and rainwater harvesting systems; and (3) watershed-scale modeling and optimization of stormwater control and treatment practices. Common research themes emerging from this collection of studies include potential to enhance hydrologic and pollutant treatment performance of stormwater practices via media amendments and the use of innovative outlet control structures, as well as development of a more mechanistic understanding of hydrologic and water-quality functions to inform modeling and performance predictions. These studies serve to expand the field's knowledge base and will inform future efforts to further improve stormwater control and treatment at various spatial and temporal scales.

“…With the supply of water and solutes, the hyporheic zone governs important physicochemical processes such as redox reactions, contaminant filtration, and the cycling of nitrogen, carbon, and phosphorus, and creates a rich biocenosis composed of species that temporarily and permanently dwell there (Edwards ; Packman et al ; Tonina and Buffington ; Marzadri et al ). Overall, the hyporheic zone and HE are critical to stream water quality and ecosystem function, and they have received increasing attention during stream rehabilitation (Boulton ; Hester and Gooseff ; Palanisamy and Chui ; Samuel et al ).…”

The hyporheic zone is the saturated interstitial space surrounding a stream. Water actively moves into, through, and out of the hyporheic zone, resulting in hyporheic exchange (HE), which is crucial to the physicochemical and biological processes in these systems. The HE in pool-riffle sequences is one of the most common forms of HE and has received a vast amount of attention. This study aimed to derive empirical equations to predict the scale, median residence time (RT), and flux of HE in a single pool-riffle sequence by considering stream discharge, bedform geometry, streambed hydraulic conductivity, and groundwater flow. The resulting equations, which were derived using previously published data, allow quick approximations of the mean depth, median RT, and flux of HE in a single pool-riffle sequence. Therefore, these equations can be used to conveniently and efficiently generate insights into the physicochemical and biological processes, facilitating the prediction of water quality and the restoration of HE in stream rehabilitation. The overall framework of the derived equations is also generally applicable to considering HE with additional influential factors (e.g., stream width, sinuosity, bed slope, alluvial depth) and cases with more available data.
