Calculation of the hydrological characteristics related to the structural design of 15 MW installed capacity run-of-river hydroelectric power plant (“Dzegvi HPP”) on the River Mtkvari/Alaverdashvili M., Tsintsadze N., Khupenia N., Kokaia N., Kiknadze D./Transactions IHM, GTU, 2024, Vol. 135, pp.26-31, Georg., Sum. Georg., Eng. In connection with the construction project of the “Dzegvi HPP” on the Mtkvari river, the maximum duty of water of various provisions of the Mtkvari river was calculated with its recurrence periods, according to which the maximum duty of water established in 1968 at the Dzegvi HPP, 2170 m3/s, corresponds to almost 1% provision , i.e. a case once in 100 years, the average multi-year maximum duty of water of 927 m3/s corresponds to almost 40%, i.e. once in 2-3 years.
Through the conducted research, the following parameters of the Mtkvari River were determined for the study area: 1. The average date of the beginning of the freshet - March 24; 2. The average date of the peak of the maximum freshet discharge - April 28; 3. The average date of the end of the freshet - July 5, by means of which we will have an idea of the expected variation of levels of the hydrological regime of the Mtkvari River in the intra-annual period
