Waterway — Catchment — Catchment areas

Waterway catchments are smaller divisions within a larger drainage basin area, which represents a more specific area of land that contributes to the flow of a watercourse within Brisbane City Council. A catchment is typically delineated based on the natural drainage patterns of the land, such as the flow of streams or rivers. It is defined by the topographic features and the boundaries of the land that drain into a specific tributary or section of the larger basin.水道集水区（waterway catchments）是大型流域（drainage basin）内的次级分区，该类分区指代布里斯班市议会（Brisbane City Council）所辖范围内，为某一河道（watercourse）径流提供补给的具体陆地区域。集水区通常依据地表自然汇流格局（如溪流、河流的径流路径）进行划定，其边界由地形特征以及汇入大型流域特定支流或河段的陆地区域范围共同界定。
