Latif, M: Rainfall-Runoff Relationship in a Local Small Wate

Pakistan lies in arid to semi arid zone and annual rainfalls vary from 5 to 14 inches in plains and above 20 inches in the northern areas. Overall about 9 MAF net rainfall‘s volume is estimated to reach the irrigation system annually. The rainfall zones, where runoff data is not available, estimation of runoff from rainfall is a difficult job.Mathematical models for estimating runoff from rainfall data are in use by hydrologists. Small catchments where hydrological data is not available and also for ungauged catchments, its difficult to apply such models. For ungauged catchments, estimation of runoff Strange table was applied in present study as its has frequent used by different agencies in Pakistan for estimating runoff volume from rainfall data for ungauged small catchments during feasibility stage of the projects. Results of the study are presented in this technical book.The authors appreciate the efforts of Barthlemy Chaton and his team in facilitating and highly acknowledge publishing of it by VDM Publishing House Ltd., for technical knowledge sharing internationally.
