Abstract:
Discharge measurements are compiled for three monitored debris-flow channels in the European Alps. There are eleven debris-flow records from Dorfbach, Switzerland, between 2011 and 2014, and one event record from Spreitgraben, Switzerland, in 2014 (Jacquemart et al. 2017). There are records of nine debris flows at Lattenbach, Austria between 2007 and 2018 (Arai et al., 2013; Hübl & Kaitna, 2021). Three of the debris-flow records from Lattenbach were split in two to remove periods with extended low flow between high flow periods (low flow periods ranging from 410 s and 540 s). Discharges were calculated from simultaneous depth and velocity measurements. Depth measurements were obtained from flow surface measurements using laser scanners and/or radar measurements. Flow velocities were obtained from geophone measurements (Dorfbach & Spreitgraben) and Doppler radar data (Lattenbach).The compiled discharge over time data has been used as an input in numerical simulations of debris flows.

Comment:
Each hydrograph file name indicates the location name and date of event. For dates with multiple events/split records, the events are indicated numerically. File name format is Location_YYYYMMDD_Event. Units for the data are seconds for time, cubic meters per second for instantaneous discharge (q_instant) and cubic meters for cumulative volume (V_cumulative).
