We present a method of digital geomorphological mapping mountainous areas with legend consisting three-tiered nested hierarchy using two case study from Vorarlberg, Austria. Users can easily visualize maps in geographical information system (GIS) at the finest level 33 morphogenetic domains. Reclassification classes an automated GIS-workflow generates medium and high levels hierarchy, each tier...
Dust emission and sand mobilization are the common natural hazards in desert roads of Iran, which originate from geomorphological facies of road margin. In this study, the geomorphological units of Yazd-Meybod road margin were distinguished, and the samples were taken from these facies as origin area while roads sediment as the transition area of sediments. The samples were analyzed using morph...
Using the ARGUS detector at the e+e storage ring DORIS II, we have measured the Michel parameters , , and for ! l decays in -pair events produced at center of mass energies in the region of the resonances. Using ! as spin analyzing tags, we nd e = 0:68 0:04 0:08, e = 1:12 0:20 0:09, e = 0:57 0:14 0:07, = 0:69 0:06 0:08, = 1:25 0:27 0:14 and = 0:72 0:18 0:10. In addition, we report the combine...
In the presence of nuisance parameters, we derive an explicit higher order asymptotic formula to compare the expected lengths of conndence intervals given by likelihood ratio statistics arising from the usual proole likelihood and various adjustments thereof. Highest posterior density regions, with approximate frequentist validity, are also included in the study.
[1] Recession flows in a basin are controlled by the temporal evolution of its active drainage network (ADN). The geomorphological recession flow model (GRFM) assumes that both the rate of flow generation per unit ADN length (q) and the speed at which ADN heads move downstream (c) remain constant during a recession event. Thereby, it connects the power law exponent of –dQ/dt versus Q (discharge...
Cosmic ray exposure ages for formation of perched alluvial terraces and for abandonment of an alluvial/debrisflow fan on opposite sides of the Tangtse Valley (the outflow at the northwest end of Lake Panggong, which is in the Karakorum Range of Western Tibet) provide evidence of a humid period at V11.5 to V7 ka. This is consistent with other regional records and supports a controversial chronol...
