The connection between tectonic conditions of development and geomorphological features of the coast of the Kherson region was analyzed in the relevant article. Geomorphological features of the coastal zone were considered from the position of the block structure of the Karkinit-Sivash system of troughs. For the first time, the attention was referr...

Within the northern coast of the Sea of Azov there are some accumulative forms that have similar morphological, morphodynamic and lithodynamic characteristics. These forms of the sea relief united in the group of «azov type» spits. At the present time the investigated accumulative forms develop under conditions of intense erosion. The research carr...

The coastal zone of the World Ocean is a very important link in the global lithodynamic system, consisting of difficult developing structures that are subdivided into abrasion, abrasion-accumulative and accumulative systems according to the nature of the substance’s direction. Abrasion-accumulative coastal systems are the most difficult. These n...

Coastal systems that are diverse in evolutionary direction have become widespread in the coastal zone of the World Ocean, among which the most specific type is “Winged foreland”. Excretion of the corresponding type is due to the presence in the coastal system of certain genetic features of lithodynamic, hydrodynamic, morphological, and evolutionary...

Global climate change could lead, already by 2100, to an increase in the average sea level of the World's oceans by 0.63–1.01 meters. Rising levels will lead to active transformation of the coastal zone, especially within coastal sandy accumulative forms. The evolution of sandy coastal accumulative forms can have different trends. In this context,...

Within coastal barriers of non-tidal seas, channels that episodically form and function for a period of time, are called breaches or prorvas (Zenkovich, 1960; Pravotorov, 1966; Shuisky, 1989; Davydov, Karaliunas, 2022; Buynevich, Davydov, 2023). Prorvas are genetically similar to tidal inlets (Fig. 1), but functionally differ from them since they d...

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...

Fish remains (ichthyo-fossil assemblages) offer important information about past ecosystems and serve as taphonomic indicators of sedimentation and burial history. In recent years, several sets of fish remains have been collected from lagoonal mark outcrops exposed along the shores of the Curonian Lagoon, Lithuania. Unfortunately, due to ongoing er...

At the current stage of the development of our planet, global climate changes are very actively manifested, causing the intensification of hydrodynamic and coastal processes in the coastal zone of the World Ocean. In the presented conditions, the greatest dynamic changes occur within the coastal barriers, which occupy about 13% of the length of the...

Most barrier coasts of the world are characterized by tidal processes, which are especially important in maintaining tidal inlets and backbarrier wetlands. However, in many semi-enclosed or isolated sea basins (Baltic et al.), tidal component has minimal or no influence and are functionally non-tidal. In recent decades, the use of ground-penetratin...

The Dniprovsko-Buzky liman is a semi-enclosed water body located in the lower part of the mouth area (estuary) of the Dnipro and the Pivdennyy Bug. The studied liman is located within a tectonic depression that is characterized by asymmetric slopes. The northern slope of the depression is steeper and characterized by a predominance of positive tect...

The longshore sediment transport (LST) along the southeastern Baltic Sea basin extends from the Sambian Peninsula to Kolka Cape. However, many aspects of the LST are based on modeling results rather than field measurements. The aim of this study was to assess the sediment transport trends and potential provenance (regional sources) of heavy mineral...

Ephemeral inlets are important and specific components of the coastal barriers of the World Ocean. Within tidal coasts, the corresponding channels are called tidal inlets, and within non-tidal coasts-breaches (prorvas, promoiny, prorany). Ephemeral inlets are important for the development of coastal barrier systems. First of all, they perform the f...

A diverse suite of erosional features along the shoreline of Lehtma (Hiiumaa Island, Estonia) is used to assess their morphodynamic context and preservation potential. The Holocene strandplain along the eastfacing (leeward) shoreline has experienced rapid retreat due to the anthropogenically induced sediment deficit. The study site is located just...

Coastal strandplains on Saaremaa Island, Estonia, contain a rich archive of past events, which are recorded as geomorphic and lithological indicators of reworking (erosional) and depositional (accretionary) phases. This study presents a new dataset of low-field bulk magnetic susceptibility (MS) values from coastal sands as a rapid means of characte...

Global climate changes, sea level rising, storm activity intensification, and increasing anthropogenic pressure are causing the activation of destructive processes along the coasts of the World Ocean. The corresponding processes are appeared at the most dangerous rates within the coastal barriers. Within the Black Sea, the total length of coastal b...

Henichesk is a seaside resort town located on the shores of the southwestern part of the Utlyutsky liman, near the Tonka (Henichesk) Strait. Within the city, there are a large number of private hotels and apartments, and the appropriate entertainment infrastructure is built, but every year the number of vacationers is steadily declining. According...

Problem statement and purpose. There are various coastal systems in the coastal zone of the World Ocean. The most specific of them are "winged foreland". These natural formations are characterized by certain genetic features, including: morphological, lithodynamic, and hydrological. Within the Black Sea coast there are four "winged foreland": Ten...

Problem Statement and Purpose. The number of dangerous hydrological phenomena has significantly increased in the context of global climatic changes at present stage of the geosphere development. In the northwestern part of the Azov Sea the most dangerous natural processes are storm surges. Appropriate catastrophic synoptic phenomena occur with the...

The coastal zone is a complex natural formation that develops on the border between land and ocean. It is the most important link in the global lithodynamic system. The conceptual idea of the coastal zone as a system is reflected in the scientists’ works of various scientific schools. This is what determines the generally accepted use of a systemat...

The coastal system of Kinburns’ka-Pokrovs’ka-Dovgiy is located in the northwestern part of the Black Sea. Morphologically, it belongs to the “winged forelands”, and hydrodynamically it is a kind of coastal barrier. Behind barrier-based reservoirs are wetlands of international importance that are of significant conservation value. The front part of...

In the coastal zone of the oceans, there are various coastal systems, among which the most specific are “winged forelands”. Within the Black Sea coast, there are four “winged forelands”: Tendra–Dzharylgach, Kinburnska–Pokrovska–Dovgiy, Burnaska–Budatska, and Lebedyna–Ustrychna, which are named by the same structural ones. The purpose of the publica...

In the coastal zone of the oceans, coastal barriers are quite widespread. Within their limits, inlets periodically arise and exist for a certain time, which is of great geological, hydrological, ecological, and navigational significance. Along the coasts where tidal fluctuations predominate, tidal inlets stand out, which are quite well studied in t...

The purpose of the study is to conduct a deep morphogenetic analysis of the "Winged forelands" coastal systems to highlight system wide genetic features and present the most complete scientific definition, as well as to conduct morphogenetic identification and geographical allocation of these systems. Methodology. The object of the study is the "W...
