Hydrogeological assessment for planning springshed management in Bans-Pabhe

Description
-
The hydrogeological assessment of the Bans-Pabhe springshed in Pithoragarh, Uttarakhand, conducted by the Advanced Center for Water Resources Development and Management, focuses on managing local water resources effectively. The study area, positioned within the Chandaak-Aulaghat watershed, includes significant springs such as Digtoli-Seem, Bans-Pabhe, and Jajrauli-Baksil. A detailed inventory identified 131 springs, with 52 situated in the targeted springsheds. The geological framework comprises Proterozoic rock formations characterized by limestone, dolomite, and phyllite, which influence water flow and spring characteristics in the region.
Key findings reveal that the springs in the Bans-Pabhe area are primarily influenced by secondary porosity and permeability due to the presence of fractures in the rock formations. The Kafaldhungri Dhara and Kutuadhara springs are perennial, while Kasni Dhara and Pabhe Naula are seasonal. Discharge rates fluctuate significantly, particularly during lean periods, indicating a pressing need for effective recharge measures. Strategies include contour trenching and afforestation to enhance aquifer recharge, especially as agricultural practices threaten the natural water supply.
In conclusion, the assessment underscores the importance of continuous monitoring and sustainable management of groundwater resources in the Bans-Pabhe springshed. Implementing recharge techniques and protecting the existing vegetation are vital to mitigate the declining discharge rates and ensure a stable water supply for local communities dependent on these springs. Ongoing research and collaboration among stakeholders are essential for addressing water scarcity challenges in the region.
