The fluvial geomorphology of the Río Chubut valley and tributaries (~42°S, ~70°W, Argentina).

This dataset includes 49 shapefiles detailing past and present drainage of the Rio Chubut catchment headwaters, higher-level terrace framework and lower-level fluvial geomorphology of a 75 km study reach. Shapefiles are georeferenced to the Geographic coordinate system WGS1984 and suitable for use in geographical information system software such as ArcMap. Applications of these data include the visualisation and analysis of contemporary and paleo-drainage of the Rio Chubut. The original publication should be cited when data is used or referred to.
Shapefiles are sorted into 4 folders; the "Catchment" folder includes features associated with the past and present feeders to the Rio Chubut (e.g. Lakes, lateral moraines (evidence of glacial feeders) and decoupled drainage channels ("Chubut_Glacial_Catchment.shp")), the "Tributaries" folder includes individual polyline shapefiles for the tributaries feeding Rio Chubut, the "Terraces" folder include shapefiles for the higher-level terraces in the Rio Chubut and tributaries and a txt. file explaining the method and results ("1_METHOD AND RESULTS.txt") of this analysis, finally the "StudyReach" folder includes all geomorphological features mapped in the lower level valley along the 75 km study reach including polyline shapefiles detailing a variety of paleochannels and - for better visualisation -polygon shapefiles marking the boundary between fluvial surfaces.

本数据集共包含49个形状文件（Shapefile），详细刻画了丘布特河（Rio Chubut）流域源头区的历史与现今水系格局、75公里研究河段的高阶阶地构架，以及低级河谷的河流地貌特征。所有形状文件均采用WGS1984地理坐标系完成地理配准，可兼容ArcMap等地理信息系统软件。本数据集可用于丘布特河现代与古水系的可视化与分析，使用或引用本数据集时，需标注其原始文献来源。所有形状文件被划分为4个文件夹："Catchment（流域）"文件夹收录与丘布特河历史及现今汇水补给区相关的各类地理要素，包括湖泊、侧碛垄（冰川汇水的佐证）以及分离式排水河道，对应要素文件为"Chubut_Glacial_Catchment.shp"；"Tributaries（支流）"文件夹包含汇入丘布特河的各支流的单一线状形状文件；"Terraces（阶地）"文件夹收录丘布特河干流及支流区域高阶阶地的形状文件，同时附带一份说明本次分析方法与结果的文本文件"1_METHOD AND RESULTS.txt"；"StudyReach（研究河段）"文件夹涵盖沿75公里研究河段的低级河谷中全部已测绘的地貌要素，其中包含记录各类古河道的线状形状文件，以及为优化可视化效果、标记河谷冲积面边界的面状形状文件。
