Russell River Adjoint Catchments - Russell adjoint catchment areas from a 30 m digital elevation model

This dataset is the Russell River adjoint catchment areas created using ArcHydro 1.3, with a stream definition threshold of 5,000 cells. The Mossman River catchment is located in the Wet Tropics region of northeast Queensland Australia. Stream definition was determined from a flow accumulation grid which was generated from a 30 m digital elevation model (S. R. Januchowski, R. L. Pressey, J. VanDerWal and A. Edwards. 2010. Characterizing errors in digital elevation models and estimating the financial costs of accuracy. International Journal of Geographical Information Science. in press.)
Purpose:
This data set has been designed to inform conservation and management planning and decision making exercise related to freshwater ecosystems. The sub catchments have been delineated from a 30 m digital elevation model, and therefore, are suitable for addressing catchment management questions at a regional scale.
History:

本数据集为采用ArcHydro 1.3生成的拉塞尔河附属集水区，河流定义阈值设为5000个栅格单元。莫斯曼河集水区坐落于澳大利亚昆士兰州东北部的湿热带区域。河流定义基于由30米数字高程模型生成的流量累积栅格（S. R. Januchowski、R. L. Pressey、J. VanDerWal及A. Edwards，2010年，《表征数字高程模型的误差并估算精度提升的经济成本》，《国际地理信息科学期刊》，已录用）。

用途：
本数据集旨在为与淡水生态系统相关的保护与管理规划及决策工作提供参考依据。该次级集水区由30米数字高程模型勾画生成，因此适用于解决区域尺度下的集水区管理相关研究问题。
