Informatisation de la méthode Bachet
Computerization of the Bachet Method
Laboratoire national d'hydraulique, EDF Chatou
With a view to simplifying the use of the Bachet Method, an interactive software has been designed allowing for the adjustment or testing of the method on a series of flood hydrographs. The methodology implemented and computerization of simple geometrical constructions depends on the construction principles of the Bachet rules. The adjustment consists of evaluating two functions known as the " Attenuation Cord " and " Transfer Time ", and this can be carried out either on natural hydrographs or converted hydrographs. During the test, the first function converts a upstream hydrograph into an attenuated hydrograph, then the second function converts the later into a downstream hydrograph. The case concerning these confluents are currently not dealt with.
