Demand of food is increasing day by day and performance of an irrigation system is associated with infiltration characteristic of the soil. An extensive irrigation system is being developed in Greater Thal Canal area that has predominately coarser soils which results to higher deep percolation losses than the losses in other cultivated land. Soil amendments like bentonite have the potential to be used in reducing infiltration rate and improving the moisture within rootzone in irrigated environment. Infiltration was described by the Kostiakov Equation and SIRMOD model was used to estimate the performance parameters of an irrigation event. Results of the study are presented in this technical book.This book certainly enhance learning among researcher, scientists and students and helps planning research studies in meeting food demands for the survival of humanity on this globe before its too late. The author appreciate the efforts of Barthlemy Chaton and his team in facilitating during book finalization and highly acknowledge publishing of this book by VDM Publishing House Ltd., for technical knowledge sharing internationally.
