Abstract
Abstract: Rainfall being an important source of water and natural source of recharge for ground water, lakes and rivers etc., its variation forms an important subject of Study. The variation of rainfall has a direct influence on the output of agriculture, occurrence of floods and design of hydraulic structures. Earlier the variation of rainfall could not be studied with precision but the developments in the metrology science have, however, rendered the study possible and precise. The present work study involves study of temporal and spatial variation of monthly seasonal and annual rainfall data of six stations of Kashmir valley for the period 1991 to 2020, which has been used for the determination of various rainfall-time graphs. The rainfall time curves been further used to determine the trend of pattern in temporal and spatial variation and precipitation forecasting and to determine the periods of maximum and minimum rainfall and also stations of maximum and minimum rainfall. The study also involves frequency analysis of rainfall data which forms the basis for flood forecasting and design of hydraulic structures.
