Microwave remote sensing data from a spaceborne platform as a tool to monitore the hydrological cycle of a floodplain area ("Varzea") at Northeast Brazil (test site: Petrolina, Pernambuco State, Brazil).

The multiparameter characteristics of the SIR-C/X-SAR experiment (L, C and X bands, HH, HV and VV polarizations for L and C bands, VV for X band, angles of incidence from 15 graus- 55 graus) would provide an unique and excellent opportunity to improve hydrologic and agricultural studies in the microwave domain. Being so, two main objectives are established in this proposal: a) To develop an algorithm to monitor the hydrological cycle over agricultural areas, based on data derived from SAR imagery and meteorological data at a floodplain area; b) 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 related to the following radar parameters: frequency, polarization and angle of incidence.
