Abstract
Problem Statement and Purpose.The middle part of the Sukhoy Liman represents a perspective reservoir for development of the port of Ilyichevsk (Black Sea). Water- hydrology of a middle part Sukhoy Liman was not systematically studied now. The most studied there was a salinity. Article’s purpose is revealing spatial distribution’s features of hydrological water’s elements an average part of the Sukhoy Liman under the influence by natural and anthropogenous factors dining the summer time. Data&Methods. There were presented the results of carneral processing of field materials obtained dining expeditionary sruveys in the water area and in the valley of the mid-range of the Sukhoy Liman in 2016. Hydrological characteristics of water were studied in August 2016. In the water area of 1311000 m2, complex hydrological works were performed at 48 stations. Water upper layer temperature was measured with a water thermometer with the accuracy to 0,2 °C, the transparency was determined with a Sekki disk, the salinity was determined by the hydrometric method using water samples taken with the help of a bottle bathometer. Results. Transparency of water in the upper reaches of the Sukhoy Liman is determined by the relief of the bottom, the presence of aquatic vegetation, the hydrological regime of the liman, the absence or weak development of abrasion and erosion processes on the banks and bottom of the liman. Transparency varies from 0,8 m to 1,7 rn. The average transparency value is 1,5 m. Temperature of the water upper layer is changing from 23,6° C to 25,6° C. Average temperature is 24,6° C. The salinity of the surface water masses of the Sukhoy liman mid-range is determined by the hydr ological processes in the upper reaches and by the inflow / outflow of water masses into the Sukhoy liman during the drifts and surges. The minimum salinity is 13,6 %o, the maximum is 15,6 %o, and the average is 14,4%o.
