A High Resolution SWMM Model for the City of Logan Utah

This model instance represents a high resolution urban stormwater model developed using the Environmental Protection Agency's Stormwater Management Model (SWMM) for the City of Logan, Utah. It was developed as part of a larger coupled modeling effort, where the SWMM model represents only the built conveyance network of the stormwater conveyance system including pipes, inlets, outfalls, culverts, etc. This SWMM model was developed using high resolution geospatial survey data collected by Logan's public works department. This model was coupled to a larger two-dimensional hydraulic model that simulates overland and riverine flow. The SWMM model provided in this resource has, however, not been calibrated.本模型实例为针对犹他州洛根市开发的高分辨率城市雨水模型，其构建采用了美国环境保护署（Environmental Protection Agency）的暴雨管理模型（Stormwater Management Model, SWMM）。该模型作为大型耦合建模项目的一部分开发完成，其中SWMM模型仅表征雨水输送系统的已建成管网，涵盖管道、进水口、出水口、涵洞等设施。本SWMM模型基于洛根市公共工程部采集的高分辨率地理空间勘测数据构建，并已与更大尺度的二维水动力模型耦合，该模型用于模拟坡面径流与河道水流。不过本资源中提供的该SWMM模型尚未经过率定。
