| Abstract: | This paper presents the development and the application of techniques for the integration of information coming from Meteosat satellite images and rain-gauge measurements, with the purpose of estimating the rainfall pattern on a certain river basin. The proposed integration techniques are based on the definition of a data coherence problem and on the application of mathematical programming methods. The quality of the estimation procedure is evaluated by using a rainfall/runoff model for the basin which allows the generation of a hydrograph at a given section of the river, on the basis of the above estimated rainfall pattern in the upstream watershed. The comparison of the hydrograph with the observed one allows the parametric tuning of the integration procedure. |
