You may use the normalized difference water index (NDWI)

Xingwang Fan

NDWI

Amr Saleem

Thank you Richard and Xingwang,

NDWI could be used to extract shallow water when contains dense aquatic vegetations i.e. grass (see attachment) ?

Andrés de la Rosa Portilla

Hy Amr Saleem, you may use 5/6/4 (Red 5, Green 6 and Blue 4) for Landsat 8 (OLI), its perfect for land and water.

Regards

Thanks for all
