Datasets description

This dataset includes video of debris flow occurred on August 2, 2023 and July 28, 2024.

Base information

collect time	2023/08/02 - 2024/07/28
collect place	Jiangjia Ravine, Dongchuan District, Yunnan Province, China
altitude	1042.0m - 3269.0m
data size	17.9 GiB
Data time resolution

Data source description

Since 2020, high-resolution cameras (3840 × 2160 at 25 fps) have been installed on both sides of the debris-flow channel, including the observation section . Data is transmitted in real-time through a wireless relay network and can be viewed online via a mobile client APP. These cameras capture real-time footage of debris-flow movements, which can be used for research of surge flow formation, flow state assessment, and others.

Data processing method

Raw data, unprocessed.

Data quality description

The data quality is reliable.
