Abstract: Water and moisture pool locations assist improve, maintain, and perpetuate excellent environmental conditions. The watersheds of Baghdad Governorate in Iraq were investigated using the normalised difference water index (NDWI) and modified NDWI. Water indicators are calculated from Landsat-8 OLI: bands 3, 5 and 6 of the multispectral satellite images. NDWI and MNDWI values for the research region were 0.244 to -0.793 and 0.312 to -0.801, respectively. In general, water indicators show water complexes in the studied region. The MNDWI index is more accurate and efficient in investigating wet and watery regions than the NDWI index.

Keywords: normalised difference water index; NDWI; modified normalised difference water index; MNDWI; Landsat 8-OLI; remote sensing technology; Baghdad Governorate; Iraq.
