Parameterization of a Bayesian Normalized Difference Water Index for Surface Water Detection [PDF]
Geosciences, 2020 The normalized difference water index (NDWI) has been extensively used for different purposes, such as delineating and mapping surface water bodies and monitoring floods.

Drought trend analysis in a semi-arid area of Iraq based on Normalized Difference Vegetation Index, Normalized Difference Water Index and Standardized Precipitation Index [PDF]
Journal of Arid Land, 2021 Drought was a severe recurring phenomenon in Iraq over the past two decades due to climate change despite the fact that Iraq has been one of the most water-rich countries in the Middle East in the past. The Iraqi Kurdistan Region (IKR) is located in the north of Iraq, which has also suffered from extreme drought.

A Comparison of Land Surface Water Mapping Using the Normalized Difference Water Index from TM, ETM+ and ALI [PDF]
Remote Sensing, 2013 Remote sensing has more advantages than the traditional methods of land surface water (LSW) mapping because it is a low-cost, reliable information source that is capable of making high-frequency and repeatable observations.

Malaysian Journal of Applied Sciences, 2021 The years 1997/1998 and 2015/2016 saw the worst El Niño occurrence in human history. The occurrence of El Niño causes extreme temperature events which are higher than usual, drought and prolonged drought. The incident caused a decline in the ability of plants in carrying out the process of photosynthesis.

Determination of phenological dates in boreal regions using normalized difference water index [PDF]
Remote Sensing of Environment, 2005 Monitoring and understanding plant phenology are important in the context of studies of terrestrial productivity and global change. Vegetation phenology, such as dates of onsets of greening up and leaf senescence, has been determined by remote sensing using mainly the normalized difference vegetation index (NDVI).
