The main genetic types of inundations on the coast have been identified. The specific features and regularities of inundation wave transformation along the rivers and over time have been studied. Seasonal and maximal runoff of Black Sea rivers has been analyzed over a long term period. Regularities in the variations of the number of inundatios and their characteristics over the coastal area have been revealed both at the annual and long term scales. Quantitative estimates are given to the hazard and damage to the population and economic activity due to inundations in the valleys of Black Sea rivers.

An analysis of extreme characteristics of surface wind waves in the three marginal Russian seas (... more An analysis of extreme characteristics of surface wind waves in the three marginal Russian seas (Barents, Black and the Sea of Okhotsk) was performed using visual wave observations. Estimates of extreme seas, swell and significant wave heights were computed using the initial value distribution method and the peak over threshold method. Due to the use of large samples compiled for the entire seas the differences between the two methods are considerably smaller than those that would be expected for grid-cell estimates. This implies a relatively high reliability of the results. In the Barents Sea both methods demonstrate growing tendencies for the extreme wind waves, while mean values do not exhibit any significant trends. This hints at a considerable modification of the statistical distribution of wind wave heights rather than on general growth of wind seas. Some further perspectives of the analysis of regional wind wave extremes are discussed. KEY WORDS: ocean wind waves, extreme events, probability distributions Viktoria Grigorieva, Senior Researcher, P.P. Shirshov Institute of Oceanology, RAS, developed the most complete data base of visual ocean wave observations and produced global climatology of ocean wave parameters including extreme waves. Recognized expert in marine climatology, data processing and metadata attribution.

methods and results of social vulnerability and risk assessment are presented in the article. it ... more methods and results of social vulnerability and risk assessment are presented in the article. it is explored if modified methodology of the united Nations university (world risk index) can be used on different scale levels: regional, municipal and settlement. it was estimated that, despite the low value of the world risk index for Russia, southern coastal and mountain regions have high values of the risk index for hydrological phenomena because of higher frequency of the hazardous events, higher population density, and high social vulnerability. the Krasnodar region (in the southwestern part of Russia) was chosen for a detailed analysis. a municipal risk index was developed, and municipal districts in the Kuban river mouth were identified as territories with the highest risk. For verification of the index results, the percentage of vulnerable people was estimated based on opinion polls. the results can be used in further risk calculation for other hazardous phenomena.

This climatology consists of optimally analyzed gridded fields of temperature, salinity, dissolved oxygen and nutrients with 0.5-degree spatial resolution for up to 44 depth levels down to 6000 m water depth. The original quality controlled set of vertical property profiles includes both the WOCE hydrographic data and selected historical data after 1970, in order to fill areas between the WOCE sections. The optimal interpolation was performed on density surfaces. This allows to avoid production of artificial water masses in the gridded data and results in sharper horizontal gradients. Another important feature of the WGHC is the hydrostatic stability of the climatologic density profiles. <strong>TableOfContents:</strong> bottom depth; pressure; salinity; temperature; potential temperature; oxygen content; silicate content; nitrate content; phosphate content; neutral density; potential density; potential_density_range_two_standard_deviations; potential_density_range_four_standard_deviations; error_temperature_salinity; temperature_standard_deviation; salinity_standard_deviation; oxygen_content_standard_deviation; silicate_content_standard_deviation; nitrate_content_standard_deviation; phosphate_content_standard_deviation <strong>TechnicalInfo:</strong> dimensions: 341 rows x 720 columns x 44 depth levels; temporalExtent_startDate: none; temporalExtent_endDate: none; temporalResolution: none; spatialResolution: 0.5; spatialResolutionUnit: degrees; horizontalResolutionXdirection: 0.5; horizontalResolutionXdirectionUnit: degrees; horizontalResolutionYdirection: 0.5; horizontalResolutionYdirectionUnit: degrees; verticalResolution: variable; verticalResolutionUnit: m; verticalResolutionSign: positive downwards; verticalStart: 0; verticalEnd: 6000 <strong>Methods:</strong> Technical Report, Gouretski and Koltermann (2004) <strong>Units</strong> (in th [...]
