the aim of the study is the classification of landform based on elevation, slope, relief and curvature inputs (old method) and topographic position index (tpi) (new method) in the south of bojnoord. the input data for the two methods is a digital elevation model (dem). the results of topographic position index (tpi) model showed that most area of landform were covered by class 5 (plains small) ...

Many numerical landform evolution models assume that soil erosion by flowing water is either purely detachment‐ limited (i.e. erosion rate is related to the shear stress, power, or velocity of the flow) or purely transport‐limited (i.e. erosion/ deposition rate is related to the divergence of shear stress, power, or velocity). This paper reviews available data on the relative importance of deta...

Aim Land-use history can be an important determinant of ecosystem characteristics, even in landscapes that outwardly appear natural . In New England, like much of the eastern United States, the natural reforestation of agricultural lands over the past 150 years has created a predominantly forested landscape. Understanding the physiographical and historical factors controlling forest structure a...

Abstract. Modeling glacial landform evolution is more challenging than modeling fluvial evolution. While several numerical models of large-scale erosion are available, there only a few erosion, and their application over long time spans requires high effort. In this paper, simple formulation which similar to the stream-power model presented. The reproduces occurrence overdeepenings, hanging val...

In this study, the fuzzy analytic hierarchy process (AHP) is used to study the relationship between drinking water quality based on content of inorganic components and landform classes in the south of Firozabad, west of Fars province, Iran. For determination of drinking water quality based on content of inorganic components, parameters of calcium (Ca), chlorine (Cl), magnesium (Mg), thorium (TH...

Recent computer models of landform evolution have focused on surface processes of river networks and hillslopes (e.g., Ahnert, 1976; Kirkby, 1986; Willgoose et al., 1991a, b; Koltermann and Gorelick, 1992; Howard, 1994; Howard et al., 1994; Smith et al., 1997). Most of these models are based on complicated differential equations that are difficult to solve. Chase (1992) developed a cellular aut...

Abstract Under the stress of global change, rocky desertification has become a serious environmental problem in Karst Mountain area. At present, few remote sensing monitoring research works on based feature space model have been conducted and reported. In this study, Albedo-LST index point-point proposed, subsequently spatio–temporal evolution pattern driving mechanism Dafang district from 1986...

1 IGCP-476 "Monsoon evolution and tectonics-climate linkage in East Asia and its marginal seas during the late Cenozoic" The symposium is composed of four sessions, the aims of which are described below. In this session, we would like to renew our knowledge on the detailed timing and modes of growth of Tibet. Especially, we would like to incorporate new evidences on Late Cenozoic uplift and its...
