Green gutter as a Nature Based Solution for mitigation and adaptation strategy in urban environments

In recent decades, the predominant dissertation has revolved around the issue of climate change, and how human can act to tackle this problem in the urban environment [1]. The overarching goal is the reduction of the causes and the sources of climate change, in order to promote the well-being of the environment, doing the best for it [2]. However, this altruistic pursuit often contends with human predispositions toward self-interest, which are its first concern. A loftier pursuit entails not only mitigating the repercussions and proactively adapting to the yet evolving circumstances, but also doing it in the most natural and environmentally friendly way. Within this paradigm, urban environments emerge as ideal fields where to develop this prospect, particularly through the application of Nature Based Solutions [3]. Cities areas represent focal points where the impacts of climate change will be intensively felt, as they are the heart of the problem, being both victims and sources of it. Numerous sources of pollution and their consequential impacts stem from human activity [4]. Cities must enact integrated policies to achieve greater sustainability, resource efficiency, energy conservation, pollutant reduction, and effective water management [5]. The main goal of this study is to evaluate the efficacy of a gutter as a prospective green wall, in managing water rainfall. The aim is to develop and propose a system capable of mitigating the risk of inundation and flooding, since it would be able to handle extreme rainfall events.
