“…Wet detention ponds are more polluted by metals than lakes [155]. They can retain a high concentration of total metal content, nutrients, and COD [189] and, adding specific devices, the kind and concentration of retained pollutants increases [190,191]. Underground stormwater detention chambers provide similar levels of stormwater treatment as wet detention ponds and avoid thermal contamination of aquatic habitats [192].…”

“…Climate Change and thermal control: Large surface water storage SUDS have a warming effect [158,255] on their immediate surroundings and can sometimes emit greenhouse gases [211] Regulation Services. Water Quality: Pervious pavement [38,39], infiltration trenches [23], bioretention systems [46,75,91,99,100,[104][105][106][107][108], green swale [102], infiltration pond [38,150], detention pond [102,155,158,187,[189][190][191][192] (although their efficiency of nitrate removal in detention deposits varies seasonally [188]), retention pond [46,205], and artificial wetland [266] have demonstrated good efficacy at removing pollutants. However, the absence of vegetation in some techniques can degrade water quality [211].…”

Urban green infrastructure such as sustainable urban drainage systems are potential providers of ecosystem services. This paper reviews the field studies that empirically verify the potential benefits of SUDS. The cultural, provisioning, supporting, and regulating ecosystem services investigated in real cases have been studied and classified according to climatology (except for the control of urban hydrology, which has been widely corroborated). Although successful cases of runoff decontamination are numerous, there is heterogeneity in the results of the systems beyond those associated with climatic differences. The other ecosystem services have not been as widely studied, giving very variable and even negative results in some cases such as climate change control (in some instances, these techniques can emit greenhouse gases). Installations in temperate climates are, by far, the most studied. These services derive from the biological processes developed in green infrastructure and they depend on climate, so it would be advisable to carry out specific studies that could serve as the basis for a design that optimizes potential ecosystem services, avoiding possible disservices.

“…The idea of confinement of the sediment into cells was revealed by the bottom grid structure (BGS) (He & Marsalek, 2013). Cellular confinement cells (geocell) were developed by the US Army Corps of Engineers Caltrans (Caltrans, 2006) to provide soil stabilization, which is a much different solution from BGS presented by He et al (2014). Simpson et al (2018) prevented the amount of resuspended sediment by using cellular confinement cells, one of the specific geotextile products, of different sizes in their study.…”

Local scour is an important problem for hydraulic structures. The local scour in the downstream of dams causes problems such as the damage of the dam body stabilization, erosion of the slopes, and the submergence of the turbines. There are many studies investigating the local scour prediction of the downstream of the hydraulic structures, but in recent years, these studies have been replaced by studies of local scour reduction. The new idea of confining the bed materials using the geocell is becoming a popular solution. This solution can be especially used for the reinforcement of the soils. In this study, the preventability of the local scour downstream of chute channel by cellular confinement system, also known as geocell, was investigated. As a result, in case of using geocell, percentage reduction of the maximum scour depth up to 40.63% was observed.
