“…Anthropic action has contributed to significant changes in subbasins, thus influencing infiltration and surface water runoff [21][22][23][24]. The quantitative measure of network complexity of drainage systems is characterized as of 5th order for SB1, and of 3rd order for SB2.…”

“…This similarity was probably found due to the elongated format, which led the authors of this study to stating that both subbasins are favorable to the flow and present a lower risk of flooding to the population. What can compromise the existing dwellings at the site [23,24] is the increase of future housing constructions at preservation areas of subbasins [21][22][23][24].…”

“…Currently, human action can be considered as a transforming agent of the environment [21][22][23][24], capable of interfering with processes that alter relief, hydrography and vegetation cover. This comprehensive understanding of subbasins leads the researchers to customizing demands for environmental management, in order to minimize negative impacts, and to favor conservation of natural resources still existing in the areas under study.…”

Abstract:The fields of engineering, architecture and urbanism ought to ponder on constructive changes to be employed in the environment. Environmental vulnerability usually reaches sites with greater abundance of water resources that are exposed to contaminable factors, which usually become residential expansion areas, and often extrapolate city boundaries. The general objective of this study is to assess physical characteristics of the subbasins of the Curtume and Água Preta streams, located in the Paraíba do Sul watershed in the municipality of Pindamonhangaba, in the state of São Paulo (SP), Brazil. The current situation regarding this environment, based on soil type and morphometric and physiographic attributes, is specifically sought to be identified. The results show the morphological and physiographic relationships with the hydrological data that determine the natural pattern of the site, associated with anthropic actions that characterize potentialities and vulnerabilities of the area, thus determining environmental dynamics. The results demonstrate that urban sprawl and residential constructions in subbasin conservation areas should occur in a planned and strategic manner, without advancing to water conservation areas.

“…In the Global South, urban water security research largely follows the parameters of techno-managerial strategies, almost exclusively attending to water for large metropolitan regions (Krueger, Rao, and Borchardt 2019). In Brazil, urban water security research follows the goaloriented, supply-side model by interrogating the technological and governance challenges of failing reservoir and utility systems for megacities (Jacobi et al 2013;de Souza et al 2017;Petelet-Giraud et al 2018;Empinotti, Budds, and Aversa 2019). As Hoekstra, Buurman, and van Ginkel (2018) rightly pointed out, however, "The question 'security for whom' often remains unanswered" (6).…”

a Urban water security strategies commonly pivot around supply-side initiatives to mitigate scarcity, forecasted population growth, or anticipated climate change; yet, scholars have begun to expand urban water security scholarship by including alternative frameworks that incorporate equity into the analysis. Our study seeks to contribute to this equity turn by opening the investigative aperture on urban water security research in several aspects. We address the question of water security for whom, and turn our attention to the urban resident and household. We shift empirical focus to smaller urban centers in the Global South, and we develop a new assessment tool for water insecurity, the Household Water Insecurity Index (HWISI), to assess differences across the urban waterscape. We conducted this research in Forquilha (Cear a, Brazil), which represents an overlooked class of small urban centers common across Brazil's semiarid region. We draw on qualitative and quantitative data to describe household water insecurity using the HWISI. The prevalence of household water insecurity is variable, with a quarter of the population experiencing moderate to severe household water insecurity. In addition, analysis of the factors within the HWISI demonstrated how specific water insecurity domains push households across water insecurity thresholds.
