Search for: [Abstract = %22The upper sections of avalanche paths %5C(avalanche starting zones%5C) in the Tatras are being transformed by morphogenetic processes%2C both secular and rapid mass movements%2C which include avalanches. The erosion niches and scars occurring within the avalanche starting zones are most exposed to these processes. A three%5C-year monitoring of the impacts of these processes leads to the conclusion that%2C in the absence of dirty avalanches%2C the efficiency of secular geomorphological processes is low %5C(max. a few cm%5C%2Fyear%5C). Such avalanches can clearly transform the relief as is demonstrated by the results of analyses of erosion niches and scars on orthophotomaps. Furthermore%2C it was found that the direction of relief changes %5C(accumulation or erosion%5C) in the Tatras is spatially and temporally varied%2C as well as varying within individual avalanche starting zones%2C and sometimes within individual erosion niches or scars.%22]
