Intense urbanisation, combined with climate change impacts such as increased rainfall intensity, is overloading conventional drainage systems, increasing the number of combined sewer overflow events and making treatment plants outdated. There is a need for better urban planning, incorporating stormwater and flood management design in order to accurately design urban drainage networks. Geographic Information System (GIS) tools are capable of identifying and delineating the runoff flow direction, as well as accurately defining small-sized urban catchments using geospatial data. This study explores the synergies between GIS and stormwater management design tools for better land-use planning, providing a new methodology which has the potential to incorporate hydraulic and hydrological calculations into the design of urban areas. From data collection to final results, only freely available software and open platforms have been used: the U.S. EPA Storm Water Management Model (SWMM), QGis, PostgreSQL, PostGIS, SagaGIS, and GrassGIS. Each of these tools alone cannot provide all the necessary functionalities for large-scale projects, but once linked to GISWATER, a unique, fast, efficient, and accurate work methodology results. A case study of a newly urbanised area in the city of Gijón (northern Spain) has been utilised to apply this new methodology.
城市化进程的加速，加上气候变化的影响，如降雨量的增加，使得传统的排水系统不堪重负，增加了合流制污水溢流事件的发生频率，使得处理厂也变得过时。为了准确设计城市排水网络，需要更好的城市规划，将雨水和洪水管理设计纳入其中。地理信息系统（GIS）工具能够识别和划定径流流向，并使用地理空间数据准确界定小型城市集水区。本研究探讨了 GIS 与雨水管理设计工具之间的协同作用，以实现更好的土地利用规划，提供了一种新的方法，有可能将水力和水文计算纳入城市设计中。从数据收集到最终结果，仅使用了免费的软件和开放的平台：美国环保署雨水管理模型（SWMM）、QGis、PostgreSQL、PostGIS、SagaGIS 和 GrassGIS。这些工具中的每一个都不能单独提供大规模项目所需的所有功能，但一旦与 GISWATER 链接，就会产生独特、快速、高效和准确的工作方法。该方法已应用于西班牙北部希洪市一个新城市化地区的案例研究。
