The Arabat Spit separates the Sivash from the sea. The Sivash is a system of shallow water lagoons that covers an area of about 2,560 km in the northeastern part of the Crimea peninsula.

A 113 km-long sandbar known as the Arabat Spit is situated in the western part of the Sea of Azov. These deposits have in turn led to an increase in the number of bays, lagoons, limans, and sandy spits in the sea. The seafloor is relatively flat due to the deposition of sand, silt, and shells by the rivers. The deposits and inflow from these rivers are responsible for the low salinity of the Sea of the Azov. Several smaller rivers also flow into the sea including the Berda, Mius, Yeya, Beysug, Molochna, Kalmius, Atmanai rivers. The two large rivers that drain into the Sea of Azov are the Don and Kuban rivers. The sea is regarded as one of the world’s shallowest seas with a maximum depth of only 14 m and an average depth of about 7 m.

The Sea of Azov measures about 360 km long and has a maximum width of 180 km.
