Morphological analysis of glaciated valleys in the Zardkuh Mountains, Iran
The morphology of glacial valley can be described in terms of power law or quadratic equations fitted to valley cross-profiles. These two models are used to study the cross-profiles of 86 valley cross-profiles in the Zardkuh Mountain in order to understand the evolutional patterns of valleys. Assessment of using the power law function indicates that b values for both valley sides range from 1.0...
متن کاملLandscape evolution of the Dry Valleys, Transantarctic Mountains: Tectonic implications
There are different views about the amount and timing of surface uplift in the Transantarctic Mountains and the geophysical mechanisms involved. Our new interpretation of the landscape volution and tectonic history of the Dry Valleys area of the Transantarctic Mountains i based on geomorphic mapping of an area of 10,000 km 2. The landforms are dated mainly by their association with volcanic ash...
متن کاملMountains, valleys, and rivers: The transmission of raccoon rabies over a heterogeneous landscape.
Landscape features may serve as either barriers or gateways to the spread of certain infectious diseases, and understanding the way geographic structure impacts disease spread could lead to improved containment strategies. Here, we focus on modeling the space-time diffusion process of a raccoon rabies outbreak across several states in the Eastern United States. Specifically, we measure the impa...
متن کاملquaternary evolutions of mountain valleys by using contour lines case study (sabalan mountains)
condition of contour lines in topographic maps, explains more geomorphologic issues such as effective processes in the land forms found in nature. change in the curvature of the transverse profile of a valley in mountainous areas, the peak of the mountain range, also reflect the geomorphologic features and expresses the tectonic events and climate changes occurring in the region. these changes ...
متن کاملOn Ridges and Valleys
Ridges and valleys are earth’s relief structures. They can have an imaging counterpart provided we model a digital image as a landscape by considering grey level values as height. These two dual entities have received comparatively little attention from the computer vision community with regard to others like edges or corners. In this paper we first propose a taxonomy or classification of the s...
