Stadia rozwoju rzeźby doliny Domagalskiego Potoku na Podhalu

Abstract

Domagalski Potok valley is situated in the western part of Podgórze Gubałowskie and it is joined with Czarny Dunajec valley (Fig. 1). It is about 2 km long and its gradient is hinger than 60‰. It is out in contact zone of ostryskie and chochołowskie beds and its direction is accordant to their run. There are 3 clear parts in its long profile which differ in relief and gradient (Fig. 2). The gradient of the upper part reaches 55‰ and relief is not rejuvenated. Within the middle part the gradient reaches 90‰ and bottom is erosionally cut and intensively deepened. In the lower part the gradient of valley is from 20 to 35‰, its bottom has a sharpe of chest incision and there are terraces along the stream channel (Fig. 1, 2). Correlation of Domagalski Potok and Czarny Dunajec Valley relief let estimate the age of particular elements and order of Pleistocene and Holocene erosional and depositional phases. Analysis of inclination map (Fig. 3), andoneage zone separation of relief show early Pleistocene rejuvenation relief of the valley. Rejuvenation comprised about 30% of the valley and reached 2/3 of its bottom. It is shown by location of Holocene erosional rapid edge within long profile of the valley. Small rejuvenation of relief of the Domagalski Potok valley should be conneceted with high resistance of the basement and with its hanging over Czarny Dunajec valley.
