I think this is a well-written and well-structured contribution that will be very valuable for the community.

report of results from a debris-flow monitoring station in the Real torrent and suggest a data processing protocol for a more consistent and transparent derivation of debris-flow parameters from field observations.

Data from 62 surges, i.e., on average approximately two surges per debris-flow event, were extracted from the records of the flow stage their analysis enabled describing the shape of the hydrographs.Ĭomiti, F., Marchi, L., Macconi, P., Arattano, M., Bertoldi, G., Borga, M., Brardinoni, F., Cavalli, M., D’Agostino, V., Penna, D., Theule, J.: A new monitoring station for debris flows in the European Alps: first observations in the Gadria basin. A paper published in NHESS (Marchi et al., 2021) describes the debris-flow dataset of the Moscardo Torrent and presents summary data (event date, number of surges per event, bulk volume, mean velocity, and peak discharge of the main surge). The catalog includes flow depth data, measured utilizing ultrasonic sensors, and rainfall. In this time interval, 30 debris flows occurred, and 26 of them were monitored by sensors installed on the channel, while four were only documented through post-event observations. More data on six debris flows that occurred between 20 will be reported in a contribution accepted for the forthcoming DFHM8 Conference (Torino, June 2023).ĭebris-flow data recorded between 19 in the Moscardo Torrent have been published in the repository PANGAEA.
A recent paper (Coviello et al., 2021) has extended the dataset by presenting data (flow velocity and bulk volume, separated in surges) from nine debris flows recorded between 20. Regarding the Gadria catchment, the paper under discussion mentions early observations on two debris flows (Comiti et al., 2014) and two more events that were used to compare the results of large scale particle image velocimetry (Theule et al., 2018). This comment aims at providing information on the availability of measurements from two sites (Gadria and Moscardo catchments) instrumented for debris-flow monitoring in Italy. I have enjoyed reading this nice paper and I agree with the authors about the importance of sharing debris-flow data in open databases. Finally, we show that Froude numbers of such surges are near critical.
Peak discharge range around a few dozens cubic meters per second. Peak flow height of surges range from 1 to 2 m. Volumes of debris-flow surges on the Réal Torrent are typically sized at a few thousand cubic meters. Raw data from three monitoring stations on the Réal torrent (drainage area: 2 km 2, South-East France) are used to illustrate an application on 34 surges measured from 2011 to 2020 on the three monitoring stations. Requirements for monitoring stations for the protocol to be applicable include (i) a flow stage measurements, (ii) a cross section hypothesis and (iii) a velocity estimation. We suggest a method to access such features at surge scale that can be applied to a wide variety of monitoring stations. Providing bulk surge features like volume, peak discharge, front height, front velocity and Froude numbers allows for numerical and experimental debris flow investigations to be designed with narrower physical ranges and thus, for deeper scientific questions to be explored.

This paper presents a protocol to analyze debris flow focusing on the surge scale rather than the full scale of the debris flow event, as well as its application to a French site.
