Irrigation Engineering Lectures & Notes for Civil Engineers


Irrigation is the controlled application of water to croplands.  Its primary objective is to create an optimal soil moisture regime for maximizing crop production and quality while at the same time minimizing the environmental degradation inherent in irrigation of agricultural lands.


Irrigation is the application of water to the soil to supplement natural precipitation and provide an environment that is optimum for crop production. Well Irrigated crops produce more food.
