“…Water quality treatment is limited to mass load reduction. A computational model of a bioinfiltration cell (similar to a bioretention cell, no underdrain) [99] in a traffic island was developed using the Hydrologic Modeling System, or HEC-HMS [100]. The authors were able to separately simulate many key hydrologic elements, such as infiltration using the Green-Ampt infiltration submodel.…”

Abstract:The continued development of urban areas in recent decades has caused multiple issues affecting the sustainability of urban drainage systems. The increase of impervious surface areas in urban regions alters watershed hydrology and water quality. Typical impacts to downstream hydrologic regimes include higher peak flows and runoff volumes, shorter lag times, and reduced infiltration and base flow. Urban runoff increases the transport of pollutants and nutrients and thus degrades water bodies downstream from urban areas. One of the most frequently used practices to mitigate these impacts is bioretention. Despite its widespread use, research on bioretention systems remains active, particularly in terms of mix design and nitrogen treatment. Recent research focusing on bioretention is reviewed herein. The use of mesocosms provides the ability to isolate particular treatment processes and replicate variability. Computational models have been adapted and applied to simulate bioretention, offering potential improvements to their operation, maintenance, and design. Maintenance practices are important for sustained operation and have also been reviewed. Predicting maintenance is essential to assessing lifecycle costs. Within these research areas, gaps are explored, and recommendations made for future work.

“…It serves to decrease the runoff, postpone the peak discharge, improve the water quality, and recharge the groundwater, mainly through infiltration and evapotranspiration, which could constitute 78% of total water input . There has been research on the infiltration of bioretention (Heasom et al, 2006), but still few on the ET of it, which is important for understanding its water budget in greater detail, especially for its complex hydrologic performance that could vary greatly due to the impact of underlying soils, physiographic regions, drainage configuration, and media depth (Brown et al, 2010).…”

Urban runoff and evapotranspiration (ET) are the major components of urban water cycle. The former links with the urban water use, groundwater recharge, and pollution transport. The latter reflects water loss back to atmosphere from urban water cycle, and greatly impacts the accurate estimation of other components such as the urban runoff. The two amounts are significant for quantitatively understanding distribution of urban water cycle, preventing of pollution transport and flood, and coping with other urban environmental management problems. ET from various land use in the urban areas have different impacts on the generation and transport of urban runoff. Besides, the accuracy of ET estimation has also greatly influenced the value of urban runoff, but the course of acquiring an accurate ET value is generally complicated and time-consuming. The aim of this paper is to present the mechanism how ET impacts runoff in urban areas and Green Infrastructures, and build up the framework of calculation of urban runoff from ET estimation, based on a deep understanding of the two processes and their associations. Through an interdisciplinary literature review the perspectives from which ET in urban areas affects the urban runoff are summarized. The methods of estimation of runoff from ET amounts, and the advantages and disadvantages of each method are critically discussed. The review forms the basis for an improvement of estimation and measurements of runoff and ET in the urban area, and a better understanding the flux transport within the urban water cycle.

“…Hunt et al [9] found that all outflow volumes were less than 50% of the inflow volumes at three bioretention field sites in North Carolina (USA) over the course of one year. Heasom et al [10] noted the absence of surface water discharge below a particular baseline event. In another study, Hunt et al [11] showed that a peak reduction of 96% was observed in storm events producing less than 4 cm of rainfall.…”

The acceleration of urbanization has resulted in the increase of urban surface runoff. Bio-swale is a promising stormwater control measure that has been proven to be hydrologically effective on urban surface runoff. Column studies were conducted to determine the optimal bio-swale composition. Results demonstrated that water reduction was proportional to inflow decrease. Columns that planted border privet and Ophiopogon japonicus showed a larger water quantity reduction compared with that of planted boxwood and ryegrass, glossy privet and Chlorophytum comosum 'Variegatum' in vegetation tests, which was the same as the order of measured transpiration capacity of the plants. Water reduction rate increases dramatically with decreasing planting soil thickness. By contrast, no significant change occurs once the thickness of the artificial filler layer is altered. The bio-swale column with a high-infiltration rate artificial filler produced a good hydrological control effect. Sand was found to be the optimal media among the selected media compositions. Although the inclusion of an additional ponding depth affected total water reduction, it produced a stable outflow. SPSS software was used to assess the relationship between water reduction rate and its influence. On the one hand, water reduction rate increased linearly with increasing water inflow, soil thickness, and ponding depth. On the other, water reduction rate grew linearly with increasing plant factor and artificial filler infiltration rate. The multiple linear regression model revealing the relationship between the water reduction effect, and its influencing factors were obtained via the stepwise regression method in the SPSS software.
