174 PATA Days 2024 of the Kaplice Furrow and the Třeboň Basin. The most significant features of this uplift can be found near Rychnov nad Malší, and on the tectonic border between the Kaplice Furrow and the Bukovský hřbet Ridge, respectively. This uplift took place probably in the late Pliocene and Pleistocene, after the sedimentation of lacustrine sediments in the Kaplice Furrow. This unevenuplift has led tomultiple streamcapturing and changes in stream direction. It is probable, that the stream of the Malše River has migrated to the E. The trunk stream of the NE part of the study area could have used the valley of the present lower Svinenský stream and had an upper part similar to the present-day Stropnice River. Generally, it appears that the distinct changes of the river geometry induced by tectonics may be younger (Pliocene or lower Pleistocene) than previously proposed (Malkovský, 1975). The study itself provides a solid base for subsequent research: it is possible to pinpoint important localities, where cosmogenic nuclides dating of the deposits can be done. After obtaining those data the tectonic evolution as well as the development of the river network in the area will be even clearer. The geomorphological and morphostratigraphical methods used in this study can also be applied to the other areas in the Bohemian Massif and other areas through the world. Tectonic activity during the Pliocene and Pleistocene was widely present, however its proper dating, scale and effect on the river geometry and terrain morphology has not been entirely clear yet.
