“…We hypothesized that sediment suspended in inflow would settle, clog surface-connected pores, and thereby degrade infiltration rates [7,8,[27][28][29]. Although we expected that soils closest to the inlets to have decreased infiltration rate and become denser with time, neither of these relationships were significant for either garden.…”

Abstract:Infiltrative rain gardens can add retention capacity to sewersheds, yet factors contributing to their capacity for detention and redistribution of stormwater runoff are dynamic and often unverified. Over a four-year period, we tracked whole-system water fluxes in a two-tier rain garden network and assessed near-surface hydrology and soil development across construction and operational phases. The monitoring data provided a quantitative basis for determining effectiveness of this stormwater control measure. Based on 233 monitored warm-season rainfall events, nearly half of total inflow volume was detained, with 90 percent of all events producing no flow to the combined sewer. For the events that did result in flow to the combined sewer system, the rain garden delayed flows for an average of 5.5 h. Multivariate analysis of hydrologic fluxes indicated that total event rainfall depth was a predominant hydrologic driver for network outflow during both phases, with average event intensity and daily evapotranspiration as additional, independent factors in regulating retention in the operational phase. Despite sediment loads that can clog the rooting zone, and overall lower-than-design infiltration rates, tradeoffs among soil profile development and hydrology apparently maintained relatively high overall retention effectiveness. Overall, our study identified factors relevant to regulation of retention capacity of a rain garden network. These factors may be generalizable, and guide improvement of new or existing rain garden designs.Keywords: wastewater; combined sewer system; hydrologic monitoring; green infrastructure; stormwater detention Highlights •Infiltration-type retention practices can aid in managing stormwater volume. •We monitored a newly-installed rain garden's hydrology over a four-year period.• Rain garden detained 50% of total inflow and delayed overflow to sewer system by~5 h. •Retention effectiveness was related to total inflow volume and intensity, evapotranspiration losses, and soil formation.

“…Infiltration basins concentrate rainwater collected over watersheds of several hectares in small areas [1]. This concentration of fluxes explains why suspended solids carried by stormwater accumulate at the soil surface and form a sedimentary layer with high trace metal and organic compound contents [2] [3]. There are many studies on the composition and characterization of sedimentary layers accumulated in stormwater infiltration basins.…”

Urban sediment generated by stormwater management techniques are highly contaminated with various trace elements. The characterization of trace element speciation and mobility are critical information to improve environmental risk assessment. This study investigates the spatial and temporal variability of major and trace element release from a sedimentary layer in Django Reinhart stormwater infiltration basin (Chassieu, eastern suburbs of Lyon, France). Sampling was conducted for 3 zones and two dates. Chemical characterization was performed (X-Ray diffraction, ICP-AES). The samples were submitted to Acid Neutralization Capacity & Base Neutralization Capacity ANC-BNC tests, according to European standard 14429 (AFNOR, 2015). Solid matrices were mixed with acid or basic solutions and physicochemical parameters and major and trace element release (i.e. Al, Ca, Fe, P, S, Si, Cu, Zn and total carbon) were followed as a function of pH. The results show that the urban sediment has no significant spatial and temporal variability with regards to element release. This observation is all the more surprising that the samples were collected in three contrasting zones regarding stormwater supply and hydric conditions. Element release follows the same trends as a function of pH with a bell-shaped solubilization curve exhibiting the highest solubility at extreme pH values. However, the samples showed slight differences concerning the release of major elements. Such differences are related to slight differences in total mineral contents (organic matter, carbonates…) and chemical composition of the sediments. The results show that despite the varying environmental conditions, the sediment chemical properties can be considered as very stable and uniform over space, dependent mainly on the local geochemical context and watershed characteristics.

“…Beerkan infiltration data were interpreted using the "BEST" algorithm (Lassabatere et al, 2006), which derives the entire set of hydraulic parameters through fitting infiltration data on the analytical infiltration model proposed by Haverkamp et al (1994). This model has been recently validated on generated numerical data (Lassabatere et al, 2009) and field data including coarse materials (Di Prima et al, 2016;Lassabatere et al, 2010;Nasta et al, 2012;Yilmaz et al, 2013Yilmaz et al, , 2010. The mean saturated hydraulic conductivity was 3.5.10 -5 m/s.…”

Artificial basins are used to recharge groundwater and protect water pumping fields. In these basins, infiltration rates are monitored to detect any decrease in water infiltration in relation with clogging. However, miss-estimations of infiltration rate may result from neglecting the effects of water temperature change and air-entrapment. This study aims to investigate the effect of temperature and air entrapment on water infiltration at the basin scale by conducting successive infiltration cycles in an experimental basin of 11869 m 2 in a pumping field at Crepieux-Charmy (Lyon, France). A first experiment, conducted in summer 2011, showed a strong increase in infiltration rate; which was linked to a potential increase in ground water temperature or a potential dissolution of air entrapped at the beginning of the infiltration. A second experiment was conducted in summer, to inject cold water instead of warm water, and also revealed an increase in infiltration rate. This increase was linked to air dissolution in the soil. A final experiment was conducted in spring with no temperature contrast and no entrapped air (soil initially water-saturated), revealing a constant infiltration rate. Modeling and analysis of experiments revealed that air entrapment and cold water temperature in the soil could substantially reduce infiltration rate over the first infiltration cycles, with respective effects of similar magnitude. Clearly, both water temperature change and air entrapment must be considered for an accurate assessment of the infiltration rate in basins.
