Analysis of precipitation variability over Satluj Basin, Himachal Pradesh, India: 1901–2013

Himachal Pradesh is a mountainous state in the Indian Himalayas, which spreads over an area of 55,000 km2. The state has a unique geography, which influences the climatic variability of the state. In the present study, Satluj Basin has been considered as a study area. This basin experiences frequent...
