Genetic diversity of inlet systems along non-tidal coasts: examples from the Black Sea and Sea of Azov (Ukraine)

In the coastal zone of oceans, barriers are quite widespread. Within their limits, inlets periodically arise and exist for a certain time, which is great geological, hydrological, ecological, navigational significance. Along coasts where tidal fluctuations predominate, stand out, well studied in terms genesis, morpho-, hydro- litho-dynamics. Inland, semi-isolated marine basins, do not reach significant amplitude, called non-tidal seas. seas, channels develop, breaches or prorvas. Breaches often mentioned specialized literature along but they have been purposefully studied. this article, we tried to analyze conditions formation prorvas within seas based on many years research. We identified four hydrodynamic situations formed. The presented variety allows us identify describe genetic types prorvas: storm-generated, storm-surge-generated, wind-stress-generated, river-stress (fluvially induced). article first attempt characteristics breaches.
