The paper considers the territory of the Black Sea coast of North-West Caucasus, to determine the complexity and the degree of variability of the engineering-geological conditions as factors of the degree of a local seismic hazard changing. A complex studying of the territory has been executed, the major engineering-geological factors defining the specifics of microseismic zoning, have been defined. The engineering-geological and seismic properties of the main stratigraphic-genetic complexes and engineering-geological elements have been analyzed. An influence of the soil conditions on seismic intensity has been specified, a calculation of the sizes of an increment of the seismic intensity for the typical conditions by means of a method of seismic rigidities has been executed. An assessment of the spatial variability of the possible sizes of an increment of seismic intensity at the sites with standard geological sections by geostatistical methods has been made. A model of a total size of the increment of the seismic intensity in the explored territory has been developed. It has been established that elements of a rank of engineering-geological subdistricts and sites, which are an analog of seismic microdistricts, are the most uniform in engineering-geological and seismic properties.

In the second half of the Ist century BC seismogenic landslide/rockfall tore off the front part of the Chirakman Cape in the western part of the Kavarna Bay. The rich quarters of the Roman city of Bisone slid down into the sea. According to data from underwater archaeology artifacts and walls of the settlement are found up to 80 m inside the sea. The paper considers the tectonic conditions, the geological-geomorphological structure of the landslide, the paleogeography of the coastal shelf during the Holocene and the hydrogeological and engineering geological conditions in the area. A reconstruction of the coastline and sea-level position during the catastrophic landslide has been developed. Stability analyses have been performed too.

Abstract Firths are geomoiphological and hydrological sites typical for flat, neutral coast of no tidal sea basins. There in the greatest extend is preserved the geological column of the correlative Pleistocene- Holocene sediments. They make possible to reveal the Quaternary evolution of the contact zone „land-sea“. Firths are one of the most reliable indicators for the Quaternary Earth crust movements. Along the Black Sea coast most widely are developed the firths in the north - west and the west periphery, where they form a classic firth type coast. This report examines the results of complex studies of Batova river firth, located (developed) on the North Bulgarian Black Sea coast.

Land Molluscs

At the end of the XX - beginning of the XXI century 85 species of the land molluscs of 49 genera and 25 families were reliably registered in the steppe zone of Ukraine. The highest species richness was recorded in the northern steppe subzone (79 species). The main centers of the species diversity are the Donetsk Upland (65% of the total number of species) and the western part of the Black Sea Lowland with the southern spurs of the Podolian Upland adjoining it (55%). The modern composition of the land molluscs fauna of the steppe zone is influenced by the proximity of the Caucasus (for the south-east of Ukraine), the Podolian Upland (for the north-west Black Sea coast) and the Crimea (for the entire investigated territory). Anthropochory plays an important role in the formation of the land molluscs complexes in the steppe zone of Ukraine.

Typical coastal elements of limans and lagoons are barriers, that separate limanic aquatories from a Seas. On limanic shores structure of the Black Sea sand barriers represented three longitudinal landscape “zones”: sea beach (“frontal”), dune-aeolian and limanic (“back of the barrier”). They closely interactive between themselves under influence of lithodynamical exchanges of sediment. General tendency of the barriers dynamics is displacement to Land direction.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.

The Black Sea, surrounded by six riparian countries, is under the threat of severe pollution, giving rise to the need of taking precautions to protect it from further deterioration. In this paper, an effort putting forth a wastewater treatment and management strategy is outlined for the Black Sea coast of Turkey, including both the technical and financial aspects. The present situation of the coast in terms of land-based pollution and infrastructure is stated, followed by an applicable management strategy. The strategy developed for the coastal settlements involves various stagewise treatment schemes based on population distribution and densities along the coastline, and on the availability of land in a specified period of thirty years. Similar strategies are proposed for the control of pollution originating from industries, for those carried by rivers joining the sea, and for leachate of solid waste landfills. The cost estimations of various treatment schemes are also given in terms of population equivalents.
