An Approach for Modeling Inter-arrival Time of Floods

P. Stoynov, P. Zlateva, and D. Velev
Abstract— The paper proposes an approach for modeling inter-arrival time of floods. It is shown that the inter-arrival time between floods can be modeled by a newly proposed type of distribution called ST distributions. The corresponding stochastic point process registering the appearances of the floods is called ST process. ST distribution and process are defined and their application to modeling flood appearances is demonstrated. The proposed approach is applied for modeling inter-arrival time between two consecutive floods based on a specific type of stochastic distributions and processes.

Index Terms— Natural disasters risk, flood, ST distribution, ST process.
