The earth has always been
referred to as a blue planet for the exclusive presence of water as compared to
other celestial bodies. This planet owes the onset and existence of life form
to this very fact that water forms the basis of life. Civilizations and
settlements were established at the banks of water sources realizing its
diversified application, importance and obligation for life. Although 70-75 %
of the earth’s surface is covered with water, all of that is not
available for use. As seen less than 1% of the world's fresh water (~0.007% of
all the water on earth) is accessible for direct application by humans .This is
the water found in lakes, rivers, reservoirs and those underground sources that
are shallow enough to be tapped at an affordable cost. Only this amount is
regularly renewed by rain and snowfall, and is therefore available on a sustainable
basis. Wetlands, the transitory area between the hydrosphere and the land are
very important with respect to; ecological aspects and its resource potential
