The field of water science and engineering includes the study of water and water resources, water purification, design and construction of dams, instruments for measuring and controlling water quality, etc. Considering that water is one of the basic resources of life and the needs of people and industries for water are constant, there are many job opportunities for graduates of this field in the labor market. If you pay attention to some fresh water news and statistics and think about the dangerous consequences of drought and its irreparable damages, what will reduce your surprise and add value to the name of this field is the engineer's relationship with water, this life-giving substance. Limitation of resources, increasing need and increasing population for engineering in the water field is so valuable and necessary that it does not need a reason or argument. In order to provide committed and expert human resources in the field of water science and engineering and in order to achieve self-sufficiency in the field of irrigation and drainage, it is necessary to train specialists who can use their knowledge and experience in the economic development.
