Chemical Nature of Hooghly (Ganga) River Water and an Assessment of their Impact on the Eco-Pedon System of Indian Botanic Garden, Howrah

The eco-pedon system of the protected premises of the Indian Botanic Garden, located along the river Hooghly in the lower gangetic plain in the district of Howrah, has been studied with a conservational point of view to understand the indiscernible phenomenon of the impact of the river water on the garden eco-pedo-chemical characteristics often submerged due to occasional tidal inundations of the river during the monsoons.

It is experimentally revealed that a chemically dilute river water siphons off the mineral riches of the submerged soil system during flash floods. The intensity of mineral erosion is noted to be directly proportional to the periodic length of submergence of the soil system notwithstanding its natural revamping capacity.
