Waterlogging is one of the most hazardous natural
occurrences, which can also be called as flood, submergence,
soil saturation, anoxia, and hypoxia, which are generally
used to describe waterlogging conditions depending upon
the moisture or water level on the field. generally, two types
of flooding are present in the field: (1) waterlogging, in which
root and some portion of the shoot goes under water, and
(2) complete submergence, where the whole plant goes under
water
