Morpholithodynamic conditions of the tip of the Hel Peninsula, the Baltic Sea

Rucińska-Zjadacz M., Rudowski S.

Oceanological and Hydrobiological Studies

2015

Vol. 44, No. 2

181--192

The Hel Peninsula is a 35 km long spit that extends into water depths of almost 60 m. Unlike most sandy barriers, the distal end of the Hel Peninsula is prograding into the deep water. This affects unique conditions for the evolution of this section of the Peninsula. The aim of this study is to determine the morpholithodynamic changes on the tip of the Hel Peninsula. Shore studies were performed in 2006-2008 and 2012. Measurements included: beach profiling, determination of shoreline and dune base line positions, and collection of sediment samples. The different nature of the eastern, central and western part of the Hel tip is evident. The eastern part is accumulative, the central part is variable with the general nature of strong and differently directed redeposition and accumulative periods, while the western part is highly erosive.

Sedimentary structure of the storm surge washover fan on the lake Bukowo spit

Rudowski S., Wróblewski R.

Oceanological Studies

2000

Vol. 29, No. 3

101-107

A storm surge washover fan on the Lake Bukowo spit (kilometre 287.3 of the Polish Baltic coast) is described in detail. The in-depth examination of the fan relief and sedimentary facies allowed to identify two subfacies represented by the fan channel and the fan core. The importance of washover fan facies for the structure and development of sandy barriers as well as for shore sediment budget and shore protection is stressed.
