The Department of Water Resources Engineering was formerly one of the five  divisions in the Department of Civil Engineering which had offered some basic courses in hydraulic, hydrology  and water resources engineering to the undergraduate students in civil, environmental and survey engineering. The division had also offered a  graduate program specialized in water resources engineering leading to the Master of Engineering Degree since 1971 and to the Doctor of Engineering  Degree since 1984. At the end of 1991, the Department of Water Resources Engineering was established to reflect growing concern of Chulalongkorn University   in the field of water resources development and management which nowaday, has become one of the nation 's most critical problems.

The  Department  offers programs  leading to the Master and Doctor of Engineering degrees in Water Resources Engineering. Works are directed toward research and professional development in  areas such as hydrology and hydrologic engineering; hydraulic engineering; irrigation engineering; groundwater; coastal engineering; and water resources planning and management.  Students who wish to continue their study in water resources engineering should have completed the equivalent of the undergraduate majoring in civil engineering or water resources engineering, or other related fields with adequate background in civil engineering.
