Узагальнено дані щодо режиму рівнів Сасика на різних етапах існування водойми. Визначено особливості сезонних коливань рівня води лиману-озера та водосховища. Проаналізовано короткострокові денівеляції рівня за даними 2013-2015 років. Встановлено фактори впливу на динаміку рівня води та вплив її на окремі абіотичні компоненти екосистеми водосховища.
Обобщены данные относительно уровневого режима Сасыка на разных этапах существования водоема. Определены особенности сезонных колебаний уровня воды лимана-озера и водохранилища. Проанализированы краткосрочные денивеляции уровня по данным 2013-2015 годов. Установлены факторы влияния на динамику уровня воды и влияние ее на отдельные абиотические компоненты экосистемы водохранилища.
In this paper have been analyzed the dynamics of the water surface of Sasyk. As a result of the researches, it has been established that level mode of Sasyk has certain features at different stages of the existence of the reservoir.
The long-term average level of the seaside reservoir (estuary-lake) was -0.31 m BS with amplitude of vibrations up to 169 cm. The level regime of the reservoir in the natural state was characterized by instability, compliance with the course of levels in the reservoir and the sea during the per&iod of their connection and the minimum levels in the absence of connection.
After anthropogenic transformation of the seaside reservoir ft the stage existence the reservoir due to the heterogeneity of the water level there were singled out an activ&e phase of transformation (1978-1985), the phase of use of the reservoir for irrigation (1986-1994), the stabilization phase (1995-2000) in the period establishment and modern period (since 2001). The average water level since the beginning existence& of the reservoir is 0,05 m BS with a magnitude of fluctuations from 36 to 253 cm. The smallest annual amplitudes distinguish the stabilization phase, and the maximum - the phase of transformation.
In the modern period, the average annual level of t&he reservoir is 0.16 m BS, which is 20 cm above the sea level in the Zhebryansky Bay.
Short-term fluctuations of the water level in the reservoir are due to the influence of the wind regime and lasts from several hours to several days with an amplit&ude of 21-31 cm.
The level mode of the reservoir at the present stage is not only an important indicator, but also one of the main factors of the ecosystem of the reservoir.
