收藏资源简介:
Specific sub-watershed located upstream from a remarkable point. A sub-watershed may be divided into several entities for DDT purposes. Definition of a catchment area: feeding surface of a watercourse or body of water. The catchment area is defined as the water collection area, considered from an outlet: it is bounded by the contour within which all water flows on the surface and underground to this outlet. Its boundaries are the dividing lines of the waters. In addition to the catchment areas defined in the BD Carthage repository on the basis of the reference river areas, procedures (e.g. control basins defined by drought protocols) or the specific needs of the services (e.g. river basins or watersheds upstream of a water intake) may lead to the creation of dedicated sub-watersheds, known as “specific watersheds” or “use watersheds” associated with particular points.
坐落于某关键点位上游的特定子流域(sub-watershed)。出于DDT相关用途,子流域可被划分为若干实体。 汇水区(catchment area)的定义:为河道或水体提供径流补给的地表。汇水区被定义为以出水口为基准的集水区域:其边界由所有地表及地下径流均汇入该出水口的等高线所围成,其边界即为分水线。 除BD Carthage数据集存储库中基于参考河道区域定义的汇水区外,各类规程(如由干旱协议划定的管控流域)或业务部门的特定需求(如取水口上游的河道流域或子流域),均可催生专用子流域,这类子流域被称为与特定点位关联的“特定流域”或“用途流域”。
