Riverbank line migration dynamics and channel evolution processes alongthe Tarim River in China

This dataset covers the Tarim River's main stream (1321 km) from 1993–2023, including: 1) 7 Landsat images (TM/ETM+, 5 - year intervals) and 2023 UAV imagery (0.06 m resolution) for river boundary extraction (UAV - validated, RMSE = 21.153 m); 2) riverbank migration rates (via 192 cross - sections, 5 km spacing) and channel evolution metrics (sediment/erosion areas, migration velocity); 3) channel - forming discharge (Pearson - III distribution) and its nonlinear relationship with migration rates (GaussAmp fitting, R² = 0.769); 4) human - activity impacts (ecological water conveyance, engineering). It supports analyzing the Tarim River's channel dynamics and anthropogenic influences.本数据集涵盖1993年至2023年塔里木河干流（全长1321千米）的相关数据，具体包含以下内容：1) 7景陆地卫星（Landsat）影像（搭载TM/ETM+传感器，时间间隔为5年）与2023年无人机（Unmanned Aerial Vehicle, UAV）遥感影像（分辨率0.06米），用于河道边界提取（经无人机影像验证，均方根误差（Root Mean Square Error, RMSE）=21.153米）；2) 基于192个间距5千米的断面计算得到的河岸迁移速率，以及河道演化指标（包括淤积/侵蚀面积、迁移速度）；3) 造床流量（采用皮尔逊III型分布拟合）及其与迁移速率的非线性关系（通过GaussAmp拟合，决定系数（Coefficient of Determination, R²）=0.769）；4) 人类活动影响要素（涵盖生态输水、水利工程）。本数据集可用于分析塔里木河的河道动态变化及其受人类活动的影响。
