To produce the food needs of the growing population in the world and to make optimal use of available water resources, it is necessary to increase the productivity of agricultural water, and a significant increase in the productivity of water used in agriculture is necessary to achieve the goals of food and environmental security. Water consumption efficiency is one of the indicators for evaluating optimal water consumption. Many methods have been studied to increase the productivity and efficiency of irrigation. Evaluating the performance of implemented drainage systems and examining their strengths and weaknesses can create a basis for planners and designers to have a more comprehensive view for optimal design in future plans and the effect of drainages. Consider increasing productivity and achieving the goals of producing food products. For this purpose, researches have been conducted on the effect of drainage on increasing productivity, and the results show the effect of this process on water productivity.
