Floods on alluvial fans: implications for reworking rates, morphology and fan hazards: experimental dataset

This file contains data characterising four alluvial fan experiments conducted in UBC’s Biogeomorphology Experimental Laboratory. Run 1 had constant flow; Runs 2-4 had alternating five-minute “flood events” and five-minute low-flows, repeated throughout each experiment. The "flood events" in Run 2 had a constant flood flow; in Run 3 they had a moderate peak that tailed off slowly; in Run 4 they had a high peak that tailed of rapidly. All experiments had the same mean flow and the same constant sediment supply. For the three repeats of Runs 1-4 (12 experiments in total), this dataset contains information on fan gradient, lateral mobility rates, and erosion and deposition rates at each minute of the experiments. There is also data on the down-fan patterns of erosion and deposition, for the five-minute flood events and the intervening low-flow periods. Data provided are from 12-hours of experimental time and onwards (each experiment was around 20 hours long in total). These data are associated with the paper “Floods on alluvial fans: implications for reworking rates, morphology and fan hazards”, by Anya Leenman, Brett Eaton and Lucy MacKenzie (2021). The paper will be submitted to JGR: Earth Surface once this dataset is publicly available.
