%X This dataset is the observation data of the ultrasonic mud level meter at the Dongchuan Debris Flow Station from 1999 to 2001. Install ultrasonic sensors in the debris flow channel, and the data is the difference between the installation height of the sensor and the depth of the debris flow mud, in meters. The installation section coordinates of sensor 1 are approximately 103.133844 ° E, 26.24744296N °, and the installation section coordinates of sensor 2 are approximately 103.13499212 ° E, 26.24779165 ° N. The data naming method is UL-YYXX: UL represents the ultrasonic sensor model, YY represents the year, and XX represents the XX th debris flow observation of that year. Regarding the specific occurrence and movement of this debris flow, it is necessary to use it in conjunction with the "overall observation" data of this platform. For example, UL-9901 refers to the mud level of the first mudslide in Jiangjia Gully measured by UL type sensors in 1999. Other information about this mudslide can be found in the data "1999-2005 Mudslide Movement Elements and Overall Observation Statistics of Jiangjia Gully in Dongchuan, Yunnan". The two data are associated with the mudslide number YYXX (9901 in the example)
