Soil waterlogging is one of the prevailing problems all over the world as it adversely affects soil and plants. In addition, it is a pre- requisite for precise agricultural management and ecological con- servation (Hassaan, 2016; Bayat et al., 2019). As the waterlogging has an influence on environmental assessment, climate change, water cycle and surface energy flux (El Hajj et al., .2016). It had become an en- vironmental hazard which is still threatening many agricultural lands along Egypt (El Sheikh et al., 2013; Belal et al., .2014; Mohamed et al., 2019). During the last three decades this problem continued to increase due to the excessive surface irrigation use with decrease in drainage efficiency. Ismailia governorate began to suffer from shallow water table levels that led to the development of saline, alkaline soils and the con of some agricultural areas into swamps (El Sheikh et al., 2013; Mohamed et al., 2013; Hammam and Mohamed, 2018).

The European Space Agency (ESA) is developing two spaceborne imaging spectrometers: The Medium Resolution Imaging Spectrometer (MERIS) and the High Resolution Imaging Spectrometer (HRIS); now renamed to PRISM, the Process Research by an Imaging Space Mission (Posselt et al. 1996). MERIS, currently planned as payload for the satellite Envisat-1 to be launched in 2002, is designed mainly for oceanographic application and covers the 0.39-1.04 ym wavelength region with 1.25 nm bands at a spatial resolution of 300 m or 1200 m. (Rast and Bezy 1995). PRISM, currently planned for Envisat-2 to be launched around the year 2003, will cover the 0.4-2.4 pm wavelength range with a 10 nm contiguous sampling interval at a 32 m ground resolution.
