Unmanned aerial vehicles (UAVs) and light detection ranging (LiDAR) can be used to analyze the geomorphic features in complex plateau mountains. Accordingly, a UAV–LiDAR system was adopted this study acquire images lidar point-cloud dataset annular structure of Lufeng, Yunnan. A three-dimensional (3D) model constructed based on from motion multi-view stereo (SfM–MVS) combination with high-resol...

iran is well known for having countless historical and instrumental records of tectonic events. shahriary catchment, as a study area, is part of the zagros collision seismic province. this research aimed to introduce a new method which is useful in identifying the relative active tectonic events of an area. the research method was designed in order to calculate the relative active tectonic inde...

In recent years, various process-based models for the evolution of regional landform systems have been developed (Coulthard, 2001). Quantitative models have considerable use in applied geomorphology, but also represent a good means we have for testing and developing theoretical models. Nevertheless, there remains a considerable gap between the detailed quantitative representation of individual ...

The main objective of this study was to investigate ecologically healthy regions near a dam reservoir. This study developed a model for assessing habitat suitability as a proxy for the ecological value of reservoirs. Three main factors comprising nine assessment variables were selected and classified as having a habitat suitability (HS) between 0 and 1: (1) geomorphic factors of altitude, slope...

abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

soil scientists have developed different mathematical equations and indices to be able to quantify soil development and to organize soil data. the main objective of the present research was the comparison of different soil development indices (including forms and ratios of iron, magnetic susceptibility, color indices, and modified harden index) related to different soils located on kerman-baft ...

Topographic asymmetry, that is, differences in the morphology of landscapes as a function of slope aspect, can be used to infer ecohydrogeomorphic feedback relationships. In this study, we document the dependence of topographic gradients and drainage densities on slope aspect and time/age in four Quaternary cinder cone fields in Arizona, Oregon, and California. Cinder cones are particularly use...
