| Zusammenfassung |
| 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 Swath mode 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 Paraná
River Delta from December 2009 to April 2010. Obtained results are consistent
with in situ measurements of river water level. |
