In the coastal zone of the oceans, coastal barriers are quite widespread. Within their limits, inlets periodically arise and exist for a certain time, which is of great geological, hydrological, ecological, and navigational significance. Along the coasts where tidal fluctuations predominate, tidal inlets stand out, which are quite well studied in t...

The main goal of the study is to evaluate changes that have occurred in the Pūčkoriai outcrop surface over the 2014–2019 period and to compare the accuracy of ground-based measurements with that of UAV aerial image models. Ground-based measurements were performed applying the original methodology, which involves comparison of the first one and subs...

Sea coast - a geomorphic system that maintains its stability through the exchange of sand between its individual elements. As environmental conditions change, the shore system changes by adapting to maintain its stability. Natural processes such as sea level fluctuation and extreme storms cause continuous shoreline change. Feedback effects create n...

Beach-foredune sediment exchange maintains a coastal system’s stability. Sea level fluctuation is one of the most important factors that modifies the beach and foredune sediment budget. This study aims to assess beach and foredune sand budget changes depending on sea level fluctuations. On the basis of annual measurements of cross-shore profiles on...

The complexity of the foredune system is responsible for its morphological diversity and different development scenarios. On wave-dominated coasts, wave activity that permanently changes foredune and beach morphometry is the main limiting factor of foredune development. Based on a field data collected on the Curonian Spit in 2002–2017, the dynamic...

Nearshore sandbars are extremely dynamic morphological features of sandy coasts, containing large volume of sand, important in sediment exchange between the beach and the nearshore. To understand dynamics of these underwater sand ridges regular and frequent observations of their cross-shore and longshore structure are required. Bathymetric surveys...

Jūros krantas – viena kaičiausių geosferos vietų žemėje. Nuolat vykstant sąnašų apykaitai tarp jūros ir kranto, stipresnės audros metu kranto profilis gali pakisti iš esmės. Tačiau, nepaisant sparčiai kintančios aplinkos, krantą sudarantys morfologiniai elementai (paplūdimys, kopagūbris) išlieka. Šio darbo tikslas – nustatyti, kaip erozinėse ir aku...
