Lidar Survey of Dump Creek, ID 2019

<p>This lidar survey of Dump Creek, ID was collected for Brian Yanites at Indiana University, Bloomington in order to quantify the impact of a late 19th century drainage diversion on landscape processes. The rerouting of Moose Creek to Dump Creek resulted in the river channel widening and undercutting the proximal valley walls, initiating scores of landslides. The data will be used to map the channel morphology, landslides, and tension cracks that continue to propagate across this landscape over a century after the drainage diversion. Data was collected in September 2019 at Dump Creek, northwest of Salmon, Idaho.</p><p><br>Publications associated with this dataset can be found at <a href=\"http://calm.geo.berkeley.edu/ncalm/dtc.html\" target=\"_blank\">NCALM's Data Tracking Center</a></p>

本激光雷达（LiDAR）勘测数据集由印第安纳大学伯明顿分校的布莱恩·亚尼茨（Brian Yanites）委托采集，针对美国爱达荷州邓普溪（Dump Creek）区域，旨在量化19世纪晚期河道改道对区域景观过程的影响。穆斯溪（Moose Creek）被改道汇入邓普溪后，致使河道展宽并掏蚀邻近谷壁，进而引发了大量滑坡。该数据集将用于绘制河道形态、滑坡及张裂缝的空间分布——这些地貌特征在河道改道一个多世纪后，仍在该区域持续扩展。数据采集工作于2019年9月在爱达荷州萨蒙市西北部的邓普溪区域完成。
