Treatment wetlands are recognized as an effective technology for mitigating the impacts of urban runoff. However, there is no consensus on the design guidelines, and the effects of some design features, such as the underdrain system, remain unexplore

Many facilities for urban drainage systems are equipped with a pipe overflow structure that can often be treated as a circular broad-crested weir. Thus it is possible to evaluate the overflow discharge through this device by measuring the water level

People around the world increasingly live in urban areas where traffic-related emissions can reach high levels, especially near heavy-traffic roads. It is therefore necessary to find short-term measures to limit the exposure of this population and no
