Stormwater — Surface Drain — Existing

This information provides a graphical representation of the locations of the existing (as constructed) stormwater surface drains in the Brisbane City Council local government area. It can be combined with other Stormwater data to provide the entire Stormwater Network. Not all assets within the network are owned, and maintained by Brisbane City Council. Surface Drains represent above-ground, exposed stormwater flow paths. These may be natural features (Natural Waterway, Open Channel) unformed features (Flat Open Surface, Overland Flowpath), or purpose-built structures (Scour Protection).本数据集以图形化形式呈现布里斯班市议会（Brisbane City Council）地方政府辖区内已建成的现有雨水地表排水渠的位置信息。该数据集可与其他雨水相关数据结合，完整还原全市雨水管网系统。并非该管网内的所有设施均由布里斯班市议会所有并维护。地表排水渠指露天设置的地面雨水径流通道，此类通道可涵盖自然地貌（天然水道（Natural Waterway）、明渠（Open Channel））、非成型地貌（平坦开放地表（Flat Open Surface）、陆地径流路径（Overland Flowpath））以及专门建造的防护结构（防冲刷结构（Scour Protection））三种类型。
