Abstract. The properties of wave-driven sediment transport and the dimensions single sedimentary compartments are often radically different in parts semi-enclosed waterbodies with an anisotropic wind climate. western, southern eastern shores Gulf Riga a remote part more than 700 km long interconnected coastal system Baltic Sea from Samland Kaliningrad District, Russia, to Pärnu Bay, Estonia. Even though gulf generally straight or gently curved, presence small headlands variations orientation...
We analyse the wave energy resource available along Pacific coast of South America from Panama at latitude 8°N to Drake Passage 55°S. The analysis is based on time series over 63 years (1959–2021) European Union Copernicus database constructed using WAM model for entire forced by wind information ERA5. novel features are temporal variations in flux, quantification contribution swells and wind-seas into potential, establishing properties most energy-carrying conditions, evaluation role El...
Abstract. The phenomenon of wave set-up may substantially contribute to the formation devastating coastal flooding in certain areas. We study appearance and properties empirical probability density distributions occurrence different heights on an approximately 80 km long section coastline near Tallinn Gulf Finland, eastern Baltic Sea. area is often attacked by high waves propagating from various directions, typical approach angle varies considerably along shore. question are approximated...
The closure depth is a key parameter in coastal processes as it characterizes the overall wave intensity nearshore and indicates water down to which storm waves are able maintain universal shape of equilibrium profiles. properties alongshore variations for eastern Baltic Sea coast evaluated at coarse resolution (5.5 km) vicinity Tallinn Bay higher (0.5 km). study based on numerical simulations wind-generated fields. It shown that, due small contribution remote swell Sea, typical ratio...
We address the possibilities of combining terrestrial (TLS) and airborne laser scanning (ALS) techniques with classical concept equilibrium beach profile to quantify changes in total sand volume slowly evolving sandy beaches.The subaerial are determined from a succession ALS surveys that were reduced same absolute height using TLS survey large horizontal surface constant elevation.The underwater waterline down closure depth evaluated an inverse Bruun Rule.The relocation is extracted...
We analyse the response of small embayed sandy beaches in marginal seas to various hydrometeorological drivers isolate a specific mechanism that may stabilise under bi-directional wind patterns. The focus is on evolution two (Pirita and Russalka) Tallinn Bay, northeastern Baltic Sea, are about 3 km apart oriented at an angle 35° with respect each other. A large proportion annual wave energy flux packed into very few days year. direction, thereby direction fields, strongest storms year...

This study explores the potential of joint use terrestrial (TLS) and airborne laser scanning (ALS) to quantify rapid spatially inhomogeneous changes subaerial beach characterize intensity coastal processes. remote sensing technology that uses pulses for acquiring high-resolution three-dimensional surface measured object is applied segment Pirita Beach (Tallinn Bay, Baltic Sea). The extent distribution erosion accumulation spots are analyzed by means creating comparing two digital terrain...

The basic properties of wave fields in the Gulf Riga, third largest semi-enclosed sub-basin Baltic Sea, are evaluated using recently digitized records coastal visual observations from island Ruhnu (57°47' N, 23°15'32" E) central part gulf and a site near south-eastern tip Sõrve Peninsula (57°54'04" 22°03'28" for 1954-2011. features climate Riga similar to those other parts Sea. long-term average heights relatively low, about 0.5 m at 0.35 Sõrve. Waves shorter than several Sea: typical...
