Detailed hydrochemical studies and field observations have shown that the structure of the marginal filter has not only frontal but also the horizontal boundary, the rate of physical and chemical processes are characterized by a different direction and magnitude. So at high tide, "heavy" dense saline water moving in the bay, fresh water flowing into propping up the p, Nameless, fresh water, more light and less solid, "spread" of marine waters, forming the entire area of the bay lateral mixing zone waters. It is important to note that the direction and velocity of the heterogeneous water masses differ both in direction and so on magnitude. During low tide, we see a different picture, and fresh and saline water moving in one direction but at different rates due to their physical and chemical properties, and in that time, at the confluence of the river is formed longitudinal vertical water mixing zone of the mobile, where they meet with one side of salty water flowing from the lagoon, fresh water rivers and salt water returning to the bay. An important factor shaping the structure of the CMF, a geomorphological characteristics of the bay – the presence of rapids and small trenches and canyons. Given the high dynamic processes due to the change of intensity and focus, the accumulation of material in the bottom precipitation occurs. It is driven out of the marginal filter, which is transported more powerful (up software cm / s) longshore currents.
Contrast zoning is largely determined by the time of year, hydrometeorological conditions, the force and direction of storms. Detailed organic-geohimicheekie studies have shown that organic carbon has terrigenous genesis, deep and low degree of conversion content (an average of 1%).
