摘要

近几十年来,双排水模型的使用有所增加,主要是因为数学方法和地理信息系统工具的进步。这种类型的模型提供了精确的诊断,并可用于评估雨水基础设施和各种排水方案。本研究分析了巴西多纳Eugênia流域的主要和次要排水关系。三种备选方案模拟了准二维水动力模型modelel。第一个备选方案只考虑地形表层,代表当前情况。在第二种方案中,引入了一个包含设计的雨水下水道的层。考虑到之前的备选方案是诊断主要次要和主要缺陷的一种方法,考虑到之前解决流域洪水的项目,制定了第三种备选方案,将它们纳入具有功能性次要排水的第二种备选方案。结果确定了次要排水间隙的位置,从而有助于将工作引向最关键的区域,优化操作并最大限度地降低维护成本。研究结果还可用于评估主要排水系统中暴雨下水道网络排放的影响,从而更好地设计排水基础设施。一旦确定了主要排水系统在洪水中的责任,就可以对其进行优化。

Multilayer modelling as a support tool for flood diagnosis and drainage system design
The use of dual-drainage models has increased in recent decades, mostly because of advances in mathematical methods and geographic information system tools. This type of modelling provides precise diagnoses and can be applied to evaluate stormwater infrastructure and diverse drainage alternatives. Minor and major drainage relations in the Dona Eugênia watershed, Brazil, were analysed in this study. Three alternatives simulated the quasi-two-dimensional hydrodynamic model Modcel. The first alternative considered only the terrain surface layer, representing the current situation. In the second alternative, a layer containing a designed storm sewer was introduced. Considering the previous alternatives as a way to diagnose the main minor and major deficiencies, a third alternative was formulated considering previous projects to solve floods in the watershed, incorporating them in the second alternative with functional minor drainage. The results identified the locations of minor drainage gaps, thus helping to direct efforts to the most critical regions, optimise operations and minimise maintenance costs. The results could also be used to evaluate the effects of storm sewer network discharges in major drainage systems, leading to better design of the drainage infrastructure. The major drainage itself can be optimised, once its responsibility in flooding is identified.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
