Hydrogeological mapping of springs in Dhankuta, Nepal

In the Hindu Kush Himalaya (HKH) region, springs are crucial potable water sources for a large population. However, these springs are rapidly disappearing, leading to a significant crisis. To address this, the International Centre for Integrated Mountain Development (ICIMOD) implemented action research and pilot projects on hydrogeology-based springshed management in the Kavre and Dhankuta districts of Nepal. The Integrate Earth System (IES) consultancy provided hydrogeological insights to delineate recharge areas.

The study, conducted in early 2024, focused on four spring sites of the RoSPro project in Dhankuta District: Bojhepani and Chanchaladevi springs in Ward 1 of Dhankuta Municipality, and Dhwoje and Kesharikharka springs in Ward 2 of Chhathar Jorpati Rural Municipality. The area, characterized by Higher Himalayan Crystalline rocks, mainly gneiss, is experiencing a decline in spring health due to road construction and other human activities, coupled with a lack of effective conservation guidelines. Additionally, downstream springs suffer from contamination due to waste dumping in tributaries.

The assessment aimed to enhance surface runoff percolation in mountain aquifers, focusing on sustaining and protecting these vital water resources. This study underscores the need for conservation measures to preserve the springs, ensuring they continue to meet the community’s water needs. The linkage between springs and roads is significant, as road construction and the absence of impactful conservation strategies greatly affect spring health and water quality.

This study was conducted as part of the Roadside Spring Protection to Improve Water Security (RoSPro) project by MetaMeta, ICIMOD, and FutureWater.
