Abstract Urban rivers are natural elements in the urban landscape that are technologically changed to solve flood and pollution problems, and as a result of these interventions in the riverbed, they can be sources of well-being or problems for different segments of a city's population. As such, alternatives for assessment from different temporal and spatial viewpoints are necessary. Here we examine the importance of an urban river which has been technologically transformed over time, through the perception of families who live alongside it. Historical background was initially used to provide context, followed by binary logistic regression to analyze survey data (stratified sample of 710 inhabitants, significance level = 0.05). The results show that perceptions varied by the type of riverbed where each respondent lived (straightened, natural, or underground) and how long residents had lived near the river, and that the technologies used influence perceptions of impacts on the quality of life in riverside populations. The findings of this study provide possibilities for evaluating urban rivers as assets that generate diffuse effects capable of intensively impacting the quality of life of various residents in different ways, with intensities moderated by the nature of the corrective technologies used in each segment of the river, as well as priorities for conservation policies developed in each community or riverside micro-society. The conclusion is that high-impact technological solutions tended to be highly effective, and despite the ongoing deterioration of water quality and escalating risk, part of the population continues to value the river as a public natural resource and believes that solutions should come from government efforts.

社会评估对技术改造的城市河流的影响

摘要 城市河流是城市景观中的自然元素，经过技术改造以解决洪水和污染问题，作为对河床的这些干预的结果，它们可以成为城市不同部分人口的福祉或问题的来源。因此，从不同的时间和空间角度进行评估的替代方案是必要的。在这里，我们通过生活在它旁边的家庭的看法来研究城市河流的重要性，该河流随着时间的推移在技术上发生了变化。最初使用历史背景提供上下文，然后使用二元逻辑回归分析调查数据（710 名居民的分层样本，显着性水平 = 0.05）。结果表明，每个受访者居住的河床类型（直的、自然的、或地下）以及居民在河流附近居住的时间，以及所使用的技术会影响对河边人口生活质量影响的看法。本研究的结果为评估城市河流作为资产提供了可能性，这些资产会产生扩散效应，能够以不同方式强烈影响各种居民的生活质量，强度由河流每个部分使用的纠正技术的性质调节，以及每个社区或河畔微型社会制定的保护政策的优先事项。结论是，高影响力的技术解决方案往往非常有效，尽管水质持续恶化和风险不断升级，
