as special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. geomorphic features of deltas are in constant transformation due to their dynamic features. constructing dams on rivers can intensify these changes and cause either negative or positive consequences. minab delta in hormozgan province of iran is a round or crescent-s...

the study of karst phenomena and its potentials has had always a particular importance in semi-arid zones of iran, specifically due to the lack of water sources. in this paper, we are going to discuss the landscape morphology in karstic areas, and the way we can have an ecological planning approach to it. maharlu karst basin was selected as the case study of karstic area, and kaftarak mount in ...

the form and morphology criteria are among  effective components in enhancement and improvement of urban environments and one of the features of successful urban spaces, is the way these criteria are arranged alongside each other especially at the visual landscape of an entrance space, because entrance of every place is the first and most important communication ring between the person and the ...

In order to strengthen the prediction of rockburst and inquire the relationship between the rockburst proneness of rock and its surface fractal characteristic, the surface fractal of the rock was studied by fractal method and uniaxial compression test. The change rules of surface fractal of different types of rock were compared by calculating its fractal dimension of rock before experiment and ...

As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences.

Spatial information plays a very important role in image understanding. Fuzzy mathematical morphology provides an effective basis for extracting binary and ternary spatial relationships by creating a fuzzy landscape where the value at each point corresponds to the relationship degree according to its position with respect to the reference object(s). We improve existing morphological approaches ...

Catchment morphology and drainage density are strongly influenced by hillslope processes. The consequences of several different hillslope process laws are explored in a series of experiments with a numerical model of drainage basin evolution. Five different models are considered , including a simple diffusive-advective process transition, a runoff-generation threshold, an erosion threshold, and...
