abstract:
The paper presents the results of a study of an abraded section of the left bank of the Domainów water reservoir on the Radonka river. The water reservoir in Domaniów was built and filled with water in 2001. At the highest state of water capacity, the reservoir accumulates 13 mln m3 of water and its surface amounts to 500 ha. With strong winds, the waves forming on the surface of the reservoir reach the height of 1 m. The abrasion activity during the year 2003 devastated about 130 m of the left bank of the mentioned water reservoir. In the year 2004, a soil and phytosociological study was made on the abraded section of the reservoir banks to determine the granulometric structure of the soil and species composition of vegetation on the abraded bank. Phytosociological releves were made at three points on the abraded segment of bank. It was found that on the abraded part of the bank there are plants with extremely differentiated habitat requirements. Hydro- and higrophytes are found on the water side of the bank, while mesophytes and xerophytes predominate on the land adjacent to the bank. plant species. In the oldest part of the bank devastated by water abrasion, shrubs and trees appear, for example Salix viminalis, S. fragilis, Populus tremula, Alnus glutinosa and Betula pendula which, having gained domination of the area, effectively protect the bank from the abrasive effect of waves.
