汉江流域输沙模数数据（1950-2018年）

本数据集针对中国南北过渡带的汉江流域，收集了1950-2018年该流域主要水文站点逐年输沙模数数据。数据集包含22个水文站点，主要通过对收集、整编历史水文年鉴资料规范化整理、分析综合而成。包含年和逐年输沙模数，数据记录数为64，数据量为278kb，数据完全开放共享。

This dataset focuses on the Hanjiang River Basin located in the north-south transition zone of China, and collects annual sediment transport modulus data from major hydrological stations within this basin from 1950 to 2018. It covers 22 hydrological stations, and is mainly developed through standardized collation, analysis and integration of collected and compiled historical hydrological yearbook data. The dataset contains both annual sediment transport modulus values and yearly time-series sediment transport modulus records, with a total of 64 data records and a data volume of 278 KB. The entire dataset is fully open for public sharing.
