CROSS-SECTIONAL MORPHOMETRY AND GEORADAR SIGNATURE OF SMALL NON-TIDAL INLET (PRORVA) CHANNELS, BLACK SEA, UKRAINE

Abstract

This study is the first comparison of a buried channel structure imaged with georadar and an active inlet (prorva) along the non-tidal Black Sea coast of Ukraine. A paleo-channel along the liman coast exhibits easterly dipping bounding surfaces (clinoforms) interpreted as a spit platform and culminates in a cut-and-fill structure (width ~5 m; depth ~1 m). An active channel with similar cross-sectional morphometry and dimensions is represented by Lazurnenska prorva along Kinburn peninsula. This comparative effort has implications to finding other buried channels along the barrier coasts and demonstrates the potential geological legacy of modern channels.
