WHAT DOES HYDROLOGY DEAL WITH ?

HYDROLOGY deals with • the waters of the earth,• their occurrence, circulation and distribution,• their chemical and physical properties, • and their reaction with their environment, • including their relation to living things.

HYDROLOGY = FULL LIFE HISTORY OF WATER ON THE EARTH !
