Rain-flowrate modelization. A contribution to the development of the DPFT method

Abstract

A whole set of algorithms seeking to improve the implementation and accuracy of the DPFT method has been proposed. In treatments concerning real data, the absence of exact reference values makes it difficult to discriminate between methods. It has therefore been decided to use data generated via a known model, whose inputs and outputs, as well as the intermediate data such as accurate rainfall and the transfer function, are known. Using accurate input and output data, or data noise-effected in a realistic manner, the most adapted algorithms, as well as the sensitivity of the method to various types of context or errors, have been able to be assessed.
