英文摘要:

Natural springs and small rivers are the major sources of water for drinking, livestock feeding, irrigation and other purposes in the Middle Hills of Nepal. The Melamchi area is in the northeastern part of Kathmandu from where the Melamchi River is considered as a major source of drinking water for the people of Kathmandu city. This paper examines the characteristics of natural springs in terms of their distribution, discharge, water utilization and conservation in the context of climate change. Out of the total surveyed springs of the Melamchi area, 93% are permanent and two-thirds of the total springs are located in mid-elevation (1500-2500m). One-fourth of the total springs are small in terms of discharge and are used for multiple purposes such as drinking, livestock, irrigation and household cleaning. Around 45% of the springs provide a source of drinking water for up to five households. Our work has shown that the water volume in about 30% of the springs has decreased over the last decade. The springs located in mid-elevation with discharge less than 5 liters per minute are more vulnerable to the impacts of climate change and anthropogenic activities. The 2015 Nepal earthquake had a huge and immediate impact on the water volume of the springs in our study with an immediate drying effect in about 18% of the springs.
