How can the most common to the most extreme rain be estimated at all points in an area? How can the rain hazard be taken into account in regional development in terms of flood risk?
The SHYPRE method (hydrograph simulation to predetermine rises in water levels) developed by Cemagref has produced a database of rain quantiles from one to 72 hours. This methods guide supplements and explains the method, with the results provided for the entire French territory put on line via the Météo-France climate library. This is currently the only method for mapping the rain risk applied to the whole of France (including overseas departments).
Having analysed various approaches and problems in predetermining the rainfall hazard, the work details the design, calibration and regionalisation stages of the rain generator. It also offers a summary of various scientific publications relating to the development of this method.
This guide will serve as a reference for everyone involved in operations (State departments and Design Offices) using the database associated with the method distributed by Météo-France. It will also be of interest to researchers involved in worst-case rain simulations.
