Chair of hydroconstruction, water systems and hydroelectric power plants

The current chair of “Hydraulic Engineering Construction, Water Systems and Hydroelectric Power Plants” was formed in the result of consolidation of Soil Mechanics, Foundations and Footings (SMF&F), current Hydraulic Engineering Construction (HEC) and Water Supply and Drainage (WSD) chairs in May 2006. The current “HEC, WS and HPP” united chair is headed by Doctor of Technical Sciences, Professor Vruyr Sargis Sargsyan.

Information on the chair is given below:

In 1968-75 Yerevan Polytechnic Institute included chair of Foundations, Footings and Construction Materials the head of which was Gurgen Karamyan.

Doctor of Technical Sciences, Associate Professor Gurgen Karamyan (1908-1986) entered the engineering department of Yerevan State University in 1927 and graduated from the department of hydraulic engineering of the ASSR Construction Institute in 1931getting the qualification of hydraulic engineer. In 1931 he was appointed as a deputy director of the ASSR Construction Institute and in 1933 of the Polytechnic Institute, then as a head of academic part, simultaneously he worked in the chair of strength of materials as an assistant. In 1949-69 he simultaneously worked in Scientific Research Institute of Hydraulic Engineering and Melioration of Armenia. In 1968 he was appointed as head of restructured chair of construction materials, footings and foundations of the Polytechnic Institute the activities of which were headed by him until 1975. He is the author of more than 30 published scientific works, including “Footings and Foundations” textbook.

Later the chair was merged with other chairs (structural mechanics, roads and bridges, Hydraulic Engineering Construction).

Up to 1982 Gurgen Karamyan, Harutyun Antonyan, Yuri Avetikyan, Galerik Shekyan and Sarkis Nurijanyan have taught ‘Soil Mechanics, Foundations and Footings’ subject.

In 1982 Doctor of Technical Sciences, Professor Vruyr Sargsyan was invited from Moscow and moved to work in Yerevan Polytechnic Institute organizing the chair of Soil Mechanics, Foundations and Footings which is headed by him from the creation date (1984) up to now.
