Improvements in irrigation can increase the productivity of water and may provide significant adaptation potential under a changing climate. The great potential of drip irrigation lies in improving water management, thus enlarging crop yield and quality. However, to design drip irrigation systems effectively, the soil water dynamics needs to be predicted using all necessary soil, plant and climate variables. In engineering terms, systems are often designed to an economic optimum, which may result in insufficient or excessive irrigation. Various models exist that can simulate the dynamics of water in the soil beneath surface drip irrigation which can help in predicting soil water content distribution.
