Réflexion actuelle sur la prévision hydrométéorologique

Thinking over hydrometeorological forecasting

SHF

Abstract

For the alert, hydrological and hydrometeorological flow rates forecasting for either all the flood hydrogram or a part of it should result from probality graduating of observed / foreseen measurements uncertainties and modelling coupled uncertainties. Forecasting the rapid flood flow rates from observed and foreseen rain falls and the slow flood flow rates and water height from upstream-downstream water propagation, leans on the transfer delais, each one specific to a catchment area. It has to be frequently updated, following Meteo France meteorological forecasting. Acquisition, transfer and data processing, rapid, reliable, flexible communications and experts in hydrology and meterology should be available.
