Phytoremediation Technique For Recharging of Water Body: A Case Study.

Abstract

Accepted 17^th September, 2017

The alarming rise in world population and its’ boundless basic needs contribute indirectly to the degradation of water resources worldwide. Depletion of vegetation cover, pollution of water from different sources, soil erosion and recession of water table has become common in many catchments. The nature has been generous in bestowing the region with bounty of water resources in form of rainwater but in the absence of scientific management of  these vital resources from rain and consequent surface flow and underground storages, the water resources go waste and creates havoc downstream. Much of the enormous water resources remain unutilized and most of the natural ponds and lakes are getting dried up due to absence of proper water resource planning and scientific management. Therefore environmental friendly and cost effective be adopted for augmentation of ground water resources to revive and rejuvenate seasonal into perennial water body. The present study is based on the concept that due to Cohesive Tension capillary movement of water from Water Table to Soil and Soil To plant is maintained in nature. Only required quantity of water remains in the plant cell and remaining water quantity enhances the Soil Moisture Conditions around the root zone. This is varying from species to species due to their morphological, anatomical and physiological features which is established in the present study and accordingly Rand D work conducted for determination of required density of identified plant species at a project site so that more than 100% Soil Moisture level could be achieved for the water recharge into the stream or low lying areas. The present study was conducted in  natural and manmade structures/methods of water recharge in 25 km² of Bhaktura Spring located in Bhimtal at Latitude.79⁰.22.41’N and Longitude E 79⁰.32.07’ at 1000 to 1600 m altitude in 25 kms radius of Nainital District. The study was conducted for four and a half years from November, 2009 – May’2013 in 25 Km² in natural Forest Conditions.
