Channel topography and grain-scale sediment structure, measured in Bury Green Brook (UK) between 2014 and 2018

Dataset contains Terrestrial laser scanner (TLS) and CT scan data collected during fieldwork on a small gravel-bed river. TLS data show the river bed surface topography collected at five intervals between September 2014 and October 2018. CT scan data show the 3D structure of sections of the river bed. CT data has been processed to segment the images into gravel grains and fine-grained matrix.

本数据集包含在小型砾石质河流野外工作期间采集的地面激光扫描（Terrestrial laser scanner, TLS）与计算机断层扫描（CT scan）数据。其中，地面激光扫描数据为2014年9月至2018年10月间分5个时段采集的河床表面地形数据；计算机断层扫描数据展现了河床断面的三维结构，且已完成图像处理，将图像分割为砾石颗粒与细粒基质。
