Abstract

Urban growth will lead cities to adopt best management practices in order to mitigate the relevant effects, such as an amplification of the hydrological cycle. The use of synthetic-aperture radar (SAR) imagery allowed us to demonstrate, over a period of 20 years (1995–2016), a massive urban development with a 70% increase in the built-up area in the Sarno River basin, in southern Italy, the most polluted river in Europe. Contextually, with the collection of an archive of damaging hydrological events that occurred during the same period, it was possible to identify a potential cause–effect relationship between their statistically significant temporal increase and the increase in the impervious area at the catchment scale provided by satellite imagery analysis. In order to restore the pre-urban development hydrological conditions, a scenario analysis was undertaken where the Storm Water Management Model was used to simulate the hydrological effect of a green roof retrofitting landscape design. SAR imagery was furthermore used to explore the potential retrofitting surfaces, leading to the definition of three different conversion scenarios, accounting for 5, 30, and 100% of potential retrofitting surfaces. The study demonstrated that…..

造成萨尔诺河流域时间变化的土地利用和破坏性水文事件:通过遥感分析实现绿色技术缓解的潜力

城市增长将导致城市采用最佳管理做法，以减轻相关影响，例如水文循环的扩大。合成孔径雷达（SAR）图像的使用使我们能够证明，在20年的时间里（1995-2016），意大利南部萨尔诺河流域的建成区面积增加了70%，这是欧洲污染最严重的河流。从上下文来看，通过收集同一时期发生的破坏性水文事件的档案，可以确定其统计上显著的时间增长与卫星图像分析提供的集水区尺度上不透水面积的增加之间的潜在因果关系。为了恢复城市发展前的水文条件，进行了情景分析，其中雨水管理模型用于模拟绿色屋顶改造景观设计的水文效果。SAR图像进一步用于探索潜在的改装表面，从而定义了三种不同的改装场景，分别占潜在改装表面的5%、30%和100%。研究表明…。。

期刊介绍： Hydrology Research provides international coverage on all aspects of hydrology in its widest sense, and welcomes the submission of papers from across the subject. While emphasis is placed on studies of the hydrological cycle, the Journal also covers the physics and chemistry of water. Hydrology Research is intended to be a link between basic hydrological research and the practical application of scientific results within the broad field of water management.
