Estimating flooded area and mean water level using active and passive microwaves: the example of Paraná River Delta floodplain
marzo 1, 2011
This paper describes a procedure to estimate both the fraction of flooded area and the
mean water level in vegetated river floodplains by using a synergy of active and passive
microwave signatures. In particular, C Band Envisat ASAR in Wide Scan mode
5 and AMSR-E at X, Ku and Ka Band, are used. The method, which is an extension
of previously developed algorithms based on passive data, exploits also model simulations
of vegetation emissivity. The procedure is applied to a long flood event which
occurred in the Paran´a River Delta from December 2009 to April 2010. Obtained results
are consistent with in situ measurements of river water level.
