Opis:
The new method of a detailed morphodynamic registration of sandy beaches has been presented. The digital oriented photograms have been taken from a stabilised point at least once a day. Occasionally also more often, for example every hour during a storm cycle. The analyses of the photograms are performed in digital mode using special computer software. This digital beach monitoring of the Polish Baltic coast was initiated in summer 2002. The test fields in Polanka Redłowska within Gdynia and Chłapowo near Władysławowo were selected. The beach areas of the length of about 200 m along the shore were registered there. Selected examples of short-term changes of the beach relief were presented. A range of spatiotemporal transformations related to different periods (hours, days, months etc.) was demonstrated.

Opis:
The paper deals with the southern part of the Baltic Sea shore zone, calIed the Coast of Szczecin, from the morpholithodynamical point of view. The coastal zone is divided into three types, namely coast, shore and nearshore. The morphodynamic character of the shore is presented in distinguished cliff and sandbar-dune areas. Further, lithological properties of the shore zone sediments are discussed. FinalIy an attempt of both qualitative and quantitative estimation of sediment supply to the nearshore zone is described, as are the natural conditions affecting its further transportation.

Opis:
The paper presents results of a study of near-bottom currents, lithology and morphodynamics on the shore-zone of the Vistula Spit in Russia and on the western shore of the Sambian Peninsula. The measurements were conducted in 1991 and during the period of 2005-2009. The study involves the analysis of the synchronous and statistical parameters of the currents together with wind, grain-size and sorting coefficient distributions for the deposits of the beach and underwater slope, and also the analysis of the morphology and morphodynamics along the east coast of the Gulf of Gdańsk. It has been shown that under conditions of an acute angle between the seaward wind vector and the coastline the strongest and the most stable longshore currents are formed. An increase of the angle leads to a decrease of velocity and stability of these currents. Under conditions of the wind normal to the shore (90°) in the sector of the curved coast Yantarny - Baltiysk (west wind), convergence of the currents is observed. The assessments of annual capacities of the longshore sediment transport for the coastal segment at the Sambian Peninsula and the deformation volumes on the underwater slope at Baltiysk are summarized. A hypothesis is proposed that the sector of 5-15 km north of Baltiysk under the existing wind-wave conditions is the zone of convergence and the discharge-resulting sediment transport. The assumption of the prevalence of migratory and whirl circulations along the shore zone of Vistula Spit is put forward. It is noticed that entrance moles of Baltiysk considerably impact on parameters of the currents and flow of deposits along the coastline at the length of 3-4 km.
