[1] Recent experimental and theoretical studies support the notion that bed load in mountain rivers can both enhance incision rates through wear and inhibit incision rates by covering the bed. These effects may play an important role in landscape evolution and, in particular, the response of river channels to tectonic or climatic perturbation. We use the channel-hillslope integrated landscape d...

this paper offers a report about the professional workshop of researching tehran which was held in august 2015 in tehran along with the fourth and fifth conference on urban landscape phenomenology. in this regard denis delbaere and frédéric poussin, experts on landscape and territorial planning, and professors of universities in france, explained their first impressions of tehran in their first...

The aim of this contribution is: (1) to present an easy to maintain robot hardware platform which allows on-line evolutionary experiments and demonstrations; (2) to introduce a simple method to measure dynamical characteristics of the time-dependent tness landscape by using reference individuals; (3) to demonstrate dynamical properties of the tness landscape based on tness measurements of refer...

landscape ecology as a modern interdisciplinary science offers new concepts, theories, and methods for land evaluation and management. a main part of landscape ecology is describing patterns in the landscape and interpreting the ecological effects of these patterns on flora, fauna, flow of energy and materials. remote sensing and gis techniques have a high ability for landscape researchers to s...

introduction:landscape structure means the pattern of a landscape, which is determined by its type of use, but also by its structure, i.e. the size, shape, arrangement and distribution of individual landscape elements. for the delineation of these landscape elements, or so-called patches, often land use or land cover units are used. in this context, “‘land cover’ refers to the physical surface ...

nowadays, the aims for assessing visual quality of landscape are to define and determine certain criteria and factors that can be used for conservation, rehabilitation and renovation of landscapes as well as determining whether a landscape is aesthetically appropriate or not. by this way, landscapes with aesthetic values are conserved and the rest are amended. analyzing the relations between vi...

the present study has been conducted on shemiranat county landscape, using lattice hexagon approach, for the first time, in order to achieve homogeneous units in degradation model. to this aim, with respect to the extent of the studied area, a lattice hexagon composed of 36 units (cells) was created and each grid cell was considered as a sub landscape. next, ecological vulnerability, degradatio...

ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. landscape planning can play a role in mitigating the effects of human-related activities. one element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...
