                         objectives are established in this proposal: a) To develop an 
                         algorithm to monitor the hydrological cycle over agricultural 
                         areas, based on data derived fwm SAR imagery and meteoro logical 
                         data at a floodplain area; h) To verify the possibility to 
                         discriminate among cultures at the date of the experiment and 
                         describe and analyse the attenuation properties of the cultures as
