A variety of factors has controlled the evolution of the Vistula river valley. They include climatically induced changes of the river runoff and sediment load, glacial advances and rapid variations of the base level, as well as the influence of the tectonic factor. The first-order climatic cycles are reflected in separate terrace fills. The second-order fluctuations may be represented by separate cuts and fills, by the 1965; D o b r a -b a szewski, 1971). During the Late Vistulian (13,OOO-10,OOO BP) and Holocene, incision followed and new sediment fills accumulated. internal structure, w h i c h may be illu-Saa Basin (Polish West Carpathians),
