A Dataset of Alluvial Fan Morphometry in the Parlung Tsangpo Basin, Southeast Tibet
Listed in ScienceDB
Alluvial fans are prevalent sedimentary formations located at the outlets of mountain rivers or gullies.
Description
Analyzing their morphometric characteristics is essential for understanding the spatial heterogeneity and developmental factors influencing these landforms. As a typical humid alpine region, the Parlung Tsangpo Basin in southeast Tibet hosts a diverse array of alluvial fans at gully mouths.
This dataset includes morphometric measurements and fan types for 133 alluvial fans and their source basins across various sub-regions of the Parlung Tsangpo Basin, encompassing the main stream of Parlung Tsangpo and its three major tributaries: Quzong Tsangpo, Bodui Tsangpo, and Yigong Tsangpo. Data were collected between 2022 and 2025 using Google Earth Pro, remote sensing imagery, field surveys, and statistical analysis.

The collection and processing procedures adhered strictly to rigorous quality control standards and standardized protocols. This dataset provides a robust foundation for investigating the morphometric characteristics and variations of alluvial fans under different environmental conditions and spatial scales.
