To investigate the erosion and deposition resulting from the debris flows, the elevation of various cross-sections was measured after the event. The cross-section elevation was measured using different methods over several decades. From 1962 to 1966, a level gauge was utilized for measurements. In the year 1999 and 2010, measurements were conducted using a total station theodolite. Starting in August 2010, a Real-Time Kinematic (RTK) surveying instrument was employed to measure the cross-section elevation.
Raw observational data, unprocessed.
The data quality is reliable.
