Abstract
In Pothwar tract, the mean monthly rainfall varies from 375 mm to 1500 mm, about 60 percent of .which is received during the monsoon season in the form of torrential rains. Due- to indiscriminate cutting of trees and removal of vegetal cover, lot of rains go waste as surface runoff, causing severe soil erosion. To find out the relationships between rainfall, surface runoff and soil loss, a study was conducted at Mangial (Fatehjang) for the three consecutive years 1983-85. It was observed that there is considerable variation in total rainfall and its intensities. There is no correlation between total rainfall and average rainfall intensities. Positive correlation between rainfall and runoff/soil loss was highly significant during 1983 and 1985 only.
