Reproduce my experiment

Clone this repository to get access to the notebooks used for Hydrological Drought Extraction and Connectedness. You'll also need to download the input files in link. Once you have the input dataset downloaded you can use the following notebooks to reproduce the analysis. For the Hydrological Drought Extraction, you should adjust the function variables moving_window in number of days, thresh_value in flow percentile and min_dur, the drought minimal duration in days.

Script Name	Description
Hydrological_drought_extraction.ipynb	Runs the hydrological drought extraction for each catchment
Hydrological_drought_connectedness.ipynb	Compute the hydrological drought connectedness
