The department of Irrigation and Water Management started functioning under the Faculty of Agricultural Engineering and Technology in the year 1964. The department was opened to meet the growing need of specialists in the field of Irrigation and Water Management for boosting up agricultural production in the country. In addition to teaching, the department, since is inception, has been working for focusing, fostering and promoting the research and extension activities in the field of Irrigation and Water Management in the country. The teacher in this department is carried out by highly qualified personnel having higher degrees mostly from abroad.

Admission into Master of Science in Irrigation and Water Management has been initiated since 1974. But, due to lack of research facilities (Laboratory, equipment etc.), it was not possible to continue this program initially. However, later on, the department overcome most of those difficulties and finally succeeded in running the program of offering the degree of Master of Science from the year 1981.
