Assessing evolving relationships between flood drivers is crucial for bivariate flood hazard quantification. We have developed a Bayesian framework to model non-stationarity of compound flood hazard based on copulas whose parameter varies with large-scale climate teleconnections.
Inside the "code" folder you will find two Stan programs that implement a dynamic Frank and Gumbel copula, respectively. In addition, in the same folder, you will find R scripts to run the analysis for the these dynamic copulas. Data from two estuaries are provided inside the "data" folder; these can be used to test the codes.
