Arid and semi-arid climate of Iran and also uneven distribution of water resources in the country necessitates optimum consumption of water resources. Main fields of activities of this department include: feasibility studies, detailed design and supervision on construction of water resources projects, dam structure, irrigation and drainage schemes, river engineering, flood control, etc. So far Over 60 projects have been completed by this department. This department consists of five teams:

• Dam Engineering
In this section, engineers apply the knowledge of geology, geotechnical, meteorology, hydrology, hydraulics, civil, structure, electrical and mechanical engineering for dam studies.

• Irrigation and Drainage
Studying, designing and supervision on construction for irrigation and drainage schemes, and drainage of urban structures and underground structures are among the activities of this team. The main tasks of elements for this team are: state-of-the-art design of irrigation and water conveyance systems, environmental impact assessment, hydraulic structures, social studies and GIS. The major fields of activities of this team are:

• Water conveyance and supply
• Rehabilitation and development of Irrigation Schemes
• Flood Control
• Design & supervision on construction of drainage networks & systems
• River Engineering

In this section, studies are carried out to address flood management and control, biological issues and land uses in bed, banks & floodplains of rivers.
River restoration, training & right-of-way delineation studies are undertaken to increase socioeconomic benefits of rivers, to stabilize river bed & banks, to create recreation sites & improve aesthetical factors, and to better use & exploit river materials such as sands & gravel resources.

• Environmental Studies
In this section, environmental impact studies have been carried out for more than 40 dams, irrigation & drainage, and river engineering projects.
