Reconsideration of hydraulic devices towards a mutual adjustment into the adaptive processes for contemporary city

Abstract

At this historic moment, marked by environmental, economic, social and not least ethical crisis, the contemporary city is affected by the co-existence and the interaction of a set of risk conditions, amplified by ongoing climate change even more. At the national and international level, one of the increased emerging critical issues is the urban water management, both in terms of resource scarcity and hydraulic and hydrogeological soils fragility. Then, of course, there are the need and the urgency to promote integrated actions related to resilient urban regeneration (Holling & Gunderson, 2002; Walker et al., 2004; Folke et al., 2010; Miller et al., 2010; Davoudi, 2012, 2013), starting both identity-making data and endogenous spatial characteristic. Moreover, this process will have to be tackled within the framework of a more general reinterpretation about the idea of urban metabolism (Wolman, 1965; Duvigneaud e Denayer-De Smet, 1977; Acebillo, 2013; Balducci, Fedeli, Curci, 2017), that acquires the resources and chains reconsideration as a representative priority. This contribution is intended to represent a possible line of thought about the role that green and blue infrastructures can take, or they are already taking, in some virtuous cases within the rewriting process of contemporary urban physiology. This procedure starting from the recognition of a potential structure able to reinterpret the urban materials, to enhance the new resources and to rephrase the intersection, opposition and overlapping links peculiar to the heterogeneity of urban landscapes.
