Channel incision characteristics in Clarksburg, MD

This dataset describes field-measured qualitative stream channel characteristics indicative of incision and remotely-measured predictions of channel incision from lidar in three headwater streams in the Piedmont physiographic region of Maryland. The files within the field-measured channel incision folder include 1) a point file of original survey locations with a description of channel characteristics and 2) a stream network file with the field-surveyed degree of channel incision classified by stream reach. The file within the model-predicted channel incision folder includes stream networks for each watershed, and the incision prediction from lidar for the years 2002, 2008, 2013, and 2018.

本数据集针对美国马里兰州皮埃蒙特地貌区的3条源头溪流，记录了野外实测的、表征河道下切(channel incision)的定性河道特征，以及基于激光雷达(LiDAR)遥感反演得到的河道下切预测结果。野外实测河道下切数据集文件夹内包含两类文件：1) 附带河道特征描述的原始测点点位文件；2) 按河段(stream reach)分类、带有野外实测河道下切程度信息的河网文件。模型预测河道下切数据集文件夹内包含各流域(watershed)对应的河网数据，以及2002、2008、2013和2018年的激光雷达(LiDAR)河道下切预测结果。
