Which case is the most suitable for flood extraction?

Microwave Toolbox
#1

I want to use the region growing technology and ChangeDetection to extract a flood area in SLC data, and i wanna know somebody else have done this experiment . I downloaded some areas but the data was always not suitable.
What area is the best?

#2

any reason why you aim to use SLC? Phase information is not of much use in this case so you could directly use the GRD products instead.

#3

This is the case in India, Is the change detection result right?
