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.
