“…In this process, the UV or visible light that radiates semiconductor material of photoanode let to occur a photocatalytic process where electron/hole pairs (e CB − /h VB + ) are generated (Reaction 8, 9 and 10) [90][91][92]. However, in a photocatalytic process, the electron/hole pairs can be recombined; in other words, the e − in the conduction band can return to the h + in the valence band, dissipating energy in form of electromagnetic radiation or heat, it affects the formation of • OH, which are mostly responsible for the degradation of organic pollutants in aqueous medium [91][92][93].…”

Glyphosate [N-(phosphonomethyl)-glycine] is a herbicide with several commercial formulations that are used generally in agriculture for the control of various weeds. It is the most used pesticide in the world and comprises multiple constituents (coadjutants, salts, and others) that help to effectively reach the action’s mechanism in plants. Due to its extensive and inadequate use, this herbicide has been frequently detected in water, principally in surface and groundwater nearest to agricultural areas. Its presence in the aquatic environment poses chronic and remote hazards to human health and the environment. Therefore, it becomes necessary to develop treatment processes to remediate aquatic environments polluted with glyphosate, its metabolites, and/or coadjutants. This review is focused on conventional and non-conventional water treatment processes developed for water polluted with glyphosate herbicide; it describes the fundamental mechanism of water treatment processes and their applications are summarized. It addressed biological processes (bacterial and fungi degradation), physicochemical processes (adsorption, membrane filtration), advanced oxidation processes—AOPs (photocatalysis, electrochemical oxidation, photo-electrocatalysis, among others) and combined water treatment processes. Finally, the main operating parameters and the effectiveness of treatment processes are analyzed, ending with an analysis of the challenges in this field of research.

“…Fassman-Beck et al (2015) investigated the effects of media composition and compaction on hydraulic conductivity and water holding capacity. Column studies can also be useful to investigate specific pollutant classes, as was completed for heavy metals (Gülbaz et al, 2015) and herbicides and herbicide surrogates (Zhang, Deletic et al, 2015). Gülbaz et al (2015) showed that the turf layer of bioretention cells had highest metals removal potential among mulch, turf, vegetative soil, sand, and gravel, with lead removal percentage highest and zinc removal percentages the lowest.…”

“…Gülbaz et al (2015) showed that the turf layer of bioretention cells had highest metals removal potential among mulch, turf, vegetative soil, sand, and gravel, with lead removal percentage highest and zinc removal percentages the lowest. Differential total phosphorus was found to be a good surrogate of for removal of glyphosate and triazines by bioretention cells, and differential ultraviolet absorbance at 254 nm was also a suitable surrogate for triazines (Zhang, Deletic et al, 2015).…”

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.

“…Various types of WSUD technologies have been developed over the past decades for sustainable urban stormwater management, such as constructed wetlands, biofilters (or raingardens), swales, ponds, etc. These natural-based systems present significant opportunities for harnessing an alternative water resource for use by cities (Hatt et al, 2006), while simultaneously helping to protect valuable waterways from excessive pollution (Hatt et al, 2009;Malaviya & Singh, 2012;Zhang et al, 2015) and ecosystem degradation (Fletcher et al, 2007), improvement of microclimate (Wong et al, 2013), and amenity values in urban landscapes (Polyakov et al, 2015).…”

Climate change and urbanisation have been challenging our cities, particularly with higher intensity of droughts and floods. For example, the state of New South Wales, Australia experienced intense drought in the winter of 2018, with over $1 billion drought relief measures supported by the state government (NSW Government, 2018). The following spring in the same year brought the worst rain in 45 years, leading to flash flooding that caused property damage, downed trees and loss of human life (BOM, 2018). There is no doubt that with climate change our cities will experience more challenges in the way they manage their water. Consequently, conventional water management approaches such as pipes and concrete channels are not good enough, and the design of resilient and sustainable water sensitive alternatives are called for. Water Sensitive Urban Design (WSUD) offers alternative solutions to urban water management, for cities to achieve 'water sensitive'. The term WSUD is commonly used to reflect a new paradigm in the planning and design of urban environments that is
