These scrips are modified from Millar et al., (2022) and Tang and Carey HydRun (2017) and users should reference these resources. \nThe sub folder 1_HydRun_Millar_cQ_functions includes an .R script containing annotated functions for event separation, hysteresis indices calculations, and plotting as well as a .csv file containing a feature definition dictionary. 2_DRB and 3_IRB contain scripts for each site along with event summary and tuning parameter output. 4_EventSummary contains a script to organize and combine data for all sites along with the final output file (WQP_HI_EventSummary_Wiecz_Final.csv) that will be used in child items three and four.
