The conditions of the formation of surface and groundwater, the regime of coastal currents depending on hydrometeorological conditions on spits of the Sea of Azov in 2023 and 2024 are investigated in the paper. Elements of the drift-gradient system of currents are expressed differently in different areas of the sea. The estuarine part of the sea (the Taganrog Bay) has a resulting flow of the stock direction with pulsations at periods corresponding to the calculated seiche periods. On the eastern coast of the Sea of Azov (Kamyshevatskaya Spit), when the wind strengthens, the anticyclonic longshore current becomes active. The set of periods of alternating current directions is different, but also falls within the range of calculated seiches. Wind surges flood the spits. The water remaining in the lagoons evaporates. As a result, the mineralization of small watercourses often exceeds the salinity of the sea several times. Differences and features of the ionic composition show that the mineralization regime of surface water bodies, such as lagoons and channels, is similar to salt marshes. The study of hydrodynamic and chemical processes on the spits thus allows us to reveal elements of the modern water movement system, as well as to understand what the dried-up Azov Sea coast looked like during periods of regression of the World Ocean.
