As so ci ate Ed i tor: Tomis³aw Go³êbiowski Re search by the Pol ish Geo log i cal Sur vey has been car ried out along the south ern Bal tic coastal zone over a dis tance of 38 km. The Bal tic Sea is clas si fied as non-tidal, and its south ern coasts are built en tirely of weakly lithified sed i men tary rocks. These de pos its form three main types of coast, namely cliffs, bar ri ers and al lu vial coasts (wetlands), with the re search fo cusing on the first two. Meth ods in clud ing re mote sens ing, map ping (geo log i cal, hydrogeological), off shore sur vey (bathymetric and geo phys i cal mea sure ments), lab o ra tory anal y ses and mod el ling re vealed a num ber of nat u ral haz ards.

“…Para as variáveis são atribuídos pesos proporcionais à influência da vulnerabilidade em um modelo analítico objetivando gerar índices numéricos que resultam em mapas temáticos temporais da vulnerabilidade ao longo de uma área costeira, como pode ser visto em Mazzer et al (2008); Mallmann e Araújo (2010); Raposeiro e Ferreira (2010). Sendo assim, diversos estudos vêm buscando formas de combater a erosão costeira, por exemplo, Ryabchuk et al (2010) apresentam um estudo de longo e curto prazo da erosão costeira ao longo da linha de costa no leste do Golfo da Finlândia. Hapke e Plant (2010) apresentam um modelo probabilístico Bayesiano para tentar prever a erosão costeira do penhasco ao norte de São Diego, Califórnia onde se verificam o aumento gradual do nível do mar e eventos episódicos ocasionados por tempestades, entre outras pesquisas.…”

RESUMOO crescimento da urbanização vem provocando grandes transformações nas relações sociais e morfológica das áreas costeiras. O presente trabalho tem como objetivo modelar massa de dados de diversas fontes como GNSS (Global Navigation Satellite Systems) e sensoriamento remoto para posteriormente prover a espacialização da vulnerabilidade costeira à erosão utilizando a lógica fuzzy. O método aplicado para análise da vulnerabilidade utilizou variáveis linguísticas, partições fuzzy, intervalos e análises paramétricas que caracterizam a modelagem fuzzy. Após análise, os níveis de vulnerabilidade à erosão costeira ao longo da linha de costa nas cidades do Recife e Jaboatão dos Guararapes no litoral de Pernambuco apresentaram os seguintes resultados: 33,33% da linha de costa possuem vulnerabilidade baixa, 38,15% possui vulnerabilidade moderada, 14,26% vulnerabilidade alta e 14,26% muito alta. Palavras-chave: Vulnerabilidade à Erosão Costeira; Cartografia Costeira; Modelagem Fuzzy; Linha de Costa.

“…At the time when the complex was planned, it was assumed that the dam would not seriously affect water areas located seaward of the dam. The present situation is compared with historical conditions in (Ryabchuk et al 2012, 2016, Kovaleva et al 2014, Leontjev et al 2015.…”

In the current study we use a three-dimensional model with hydrodynamic and spectral wave modules operating in a coupled mode to simulate the response of currents and wind wave fields to winds of 20–25 m/sec offshore of the protective structure of the Saint Petersburg Flood Prevention Facility Complex. The model was calibrated against field data, which allowed us to obtain a tool describing storm situations in the eastern part of the Gulf of Finland with a satisfactory accuracy. The numerical modeling showed that the protective dam did not have a noticeable effect on the levels of stormsurge, significantwave height, or current speed in areas seaward of the dam. The increase in erosion processes on the southern shore of the easternmost part of the Gulf of Finland in recent past has most probably been related to other factors. We found that if a west or south-west wind of at least 25 m/s blows over the Baltic Sea for at least 16 hours, the level of storm surges seaward of the dam may reach 3 or more meters. An artificial strengthening of the coastline and the creation of shore protection structures are recommended.
