Abstract
The recent geomorphodynamic situation of an area or the importance of recent geomorphological processes in a special region is difficult to measure exactly. That is extremely true for the high Arctic. Size and order of the relief-forming processes in an area as the Oobloyah Valley have to be only semi-quantitative estimations. Even if these estimations are not free of faults and errors, it seems urgent to try to get this information to develop more and better quantitative geomorphological models. For the expedition area some data could be gathered; they are not perfect, but it is believed that the values given are correct for the test area regarding their order of magnitude. ... The principal results are as follows: Related to the area affected, rockfall, solifluction and glacial processes are of the same importance. Related to volume in transport, solifluction keeps the first rank. As transport systems, rivers are dominant, but - regarding thespecific mass transport and taking into account the area involved - the following rank order can be given (cf. tab. 8): glacier - rockfall - mud / debrisflow - land slides - solifluction - slope wash. The total geomorphological specific mass transport has been estimated for the test area to: horizontal : 1, 3 * 10*6 (m*t/a/sq km) vertical : 0, 2 * 10*6 (m*t/a/sq km).Unfortunately, there are only a very few similar studies. Compared to the data given by JACKLI (1957) for the alpine basin of the Rhine (4300 sq km) these figures are only 0.4% (horizontal) and 8% (vertical). That demonstrates the influence of the broad and inactive plains in the Oobloyah Valley and the importance of a high alpine relief in the Alps. In addition it may demonstrate that not all periglacial environments are as active as in some models assumed.
