This repository contains a statistical analysis of historical discharge data from the Niger River at the Niamey station. The project estimates probabilities related to flood hazards and drought levels for the year 2023 using distribution-free, non-parametric, and parametric methods.
The compiled documents can be found in the releases. The latest built PDF of the report is available here.
