Estimated Perennial Streams in Idaho, indexed to the NHDPlus

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Perennial streams in Idaho have been modeled using regression equations for 7-day, 2-year low flows (7Q2) described in Wood and others (2009, U.S. Geological Survey Scientific Investigations Report 2009-5015). The model produces "synthetic" streams based on 10-meter resolution digitial elevation models that have been processed to agree closely with 1:24,000-scale National Hydrography Dataset flowlines.

本数据集发布于2016年10月1日之前，彼时美国地质调查局（U.S. Geological Survey, USGS）有关科学数据审核、批准与发布的政策尚未生效，该政策详见《美国地质调查局调查手册第502.8章：基础科学实践：科学数据发布的审核与批准》。爱达荷州的常年河流已采用Wood等人（2009年，美国地质调查局科学调查报告2009-5015）中所述的7天2年低流量（7Q2）回归方程完成建模。该模型基于10米分辨率的数字高程模型生成“合成”河流，且已通过处理使其与1:24000比例尺的国家水文数据集（National Hydrography Dataset）水系线高度吻合。完整内容请参阅《Larger_Work_Citation》报告文本。
