Monitoring floods in the Kafue flats with TanDEM-X data

Wetlands are very valuable ecosystem which may present fast dynamics. This study is focused on the observation of the Kafue Flats exploiting TanDEM-X polarimetric and interfer-ometric data. Several analysis are carried out considering classification, change detection and Digital Elevation Model (DEM) estimation. Specifically, it is possible to observe that differences between single-pass DEM acquired during different dates can provide promising estimations of the flood water level and extent (provided that the water is partially covered by vegetation). Additionally, the polarimetric information can add details regarding small areas in the data where swamps are presents also in dry seasons.
