The Performance of Tajan Rubber Dam in Mellal Park in City of Sari during March 2019 Flood

Building rubber dams in the northern provinces of Iran are emerging, though the function of such dams in the critical situations especially in great floods is still not given much investigations. In this paper, the function of the rubber dam constructed in Sari (the center of Mazandaran Province) is studied in the flood event of March 2019 with the peak of 880 m3/s which was exceptional in the past 100 years. As a recent structure, investigating the function of the rubber dam in this floods is very important. Investigating different parts of the dam showed some deficiencies such as failing of the automatic discharge system, lack of operating plans for flood events, lack of suitable sealing for installations which resulted in the intrusion of water into the control room. In this paper suggestions are presented for design and using the rubber dams.
