Data and Matlab code for Copula and plotting

This ZIP archive contains the following data files and analysis codes: input.csv: Observed annual precipitation extremes and their corresponding water levels for the period 1980–2024. Data for the year 1996 has been excluded due to missing water level measurements. projection.csv: Projected annual precipitation extremes and associated water levels for 2030–2049, developed under the moderate (RCP4.5) and high-emission (RCP8.5) scenarios. MATLAB Codes: The archive includes MATLAB scripts used for selecting the univariate fit, determining the appropriate copula (for multivariate analysis), and generating Figures 3–6. Each script can be run independently; the only required modification is the working directory name.
