Orographic Effects on the Distribution of Rainfall in Mula River Basin

Sharad Auti | Dr. B. B. Thavre


Abstract: The present study examined the orographic effects on the distribution of rainfall over the Mula River catchment area located in north Ahmednagar district. The 30 locations rainfall data of the last 43 years (1980-2023) was used. The basin physiography shows that the elevation has sharply declined from the northwest towards the east while the Interpolation analysis by the inverse distance weighting (IDW) method highlights that the rainfall also sharply declined from northwest to east. The regression model result indicates that an increase of 100 m elevation causes an increase of 114.77 mm of rainfall means the distribution of rainfall is controlled by elevation over the Mula River basin.
