So far as I think it would change coz refractive index will differ as depth increases.

Yousef Bahrami

As my point of view it is related to the compositions of water as well. Indeed by changing in composition, reflectance would be changed.

Selvaraj Ayyakkanu

Definitely changes will be there, this is the difficulty which we are meeting in EMR since low responsibility by water, it will be appear in negative DN value. for better result if we are use lidar technology, we can find changes since it has multiple return.
