Применение численного моделирования для расчета ветрового волнения на Крюковском водохранилище

Abstract

Purpose: testing the possibilities of using the SWAN wind wave model with input characteristics according to the data of the Krasnodar (Pashkovskiy) weather station for the Kryukovskiy reservoir. Materials and methods. The studies were carried out at the Kryukovskiy reservoir, taking into account the conditions of formation of the processes of en-vironment-improving potential formation of the territory in southern Russia, which guarantees the reliability and environmental safety of the facility operation under conditions of an in-creasing risk of natural and man-made disasters on the example of the Krasnodar Territory. Field studies and field tests were carried out according to the Kuban State Agrarian University methods. When modeling the surge overwash for two different profiles (Northern and Western water barrier dams), the SWAN model data in a one-dimensional version were compared with the data obtained by SP 38.13330.2012. Results. The SWASH model provides reliable results and is an adequate alternative calculation option. Wave field data, which provides a good foundation for further study of the climatic variability of wind waves in the Kryukovskiy reservoir have been obtained. Conclusions. As a result of surge overwash modeling for two profiles under study, it was found that on average, the marks of the existing water barrier dam slope are higher than the surge in the design storm, mainly by 0.55–0.75 m, however, at PK 9 + 00 it was revealed that the slope top elevation of the Northern water pro-tection dam corresponds to the overwash mark. Therefore, it is necessary to continue research on monitoring the engineering protection of the Kryukovskiy reservoir using mathematical modeling, which confirmed the effectiveness and information content of the applicable SWAN model at a relatively low cost.
