in this paper, an advanced formulation of the spectral finite element method (sfem) is presented and applied in order to carry out site response analysis of 2d topographic structures subjected to vertically propagating incident in-plane waves in time-domain. the accuracy, efficiency and applicability of the formulation are demonstrated by solving some wave scattering examples. a numerical param...

The present study aims to describe and bring out the tectonic nature of Ijai watershed in parts Kangpokpi, Tamenglong Noney districts Manipur. has an area 184.0 Km2which is also tectonically active as depicted by analysed values different geomorphic indices like SLK index, Valley Floor Width Height ratio (Vf),Transverse Topographic Symmetry (T), Drainage Basin Asymmetry (AF), Elongation Ratio (...

The morphotectonic analysis is a useful time-saving and cost-effective method to assess tectonic activity, especially in large regions. In this paper, the study was carried out Kerman city which southeast of Iran part Central structural zone. Despite occurrence numerous historical instrumental earthquakes around city, there gap earthquake records that has obscured its seismicity status. aim ide...

We examined the distribution of ground-flora species (herbaceous and woody species <1 m tall) across riparian areas of northeastern Wisconsin in an effort to understand how hierarchical landscape properties, such as the physiographic system (ground moraine and outwash plain), valley system (constrained and unconstrained), and valley floor landforms influence distribution patterns of ground-flor...

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...

Abstract The current study used remote sensing, GIS, and seismic data to determine the geological morphometric parameters of Wadi Beda Basin area, which is located in northwestern part Gulf Suez Province. geomorphic related with development neotectonics are deduced using Shuttle Radar Topography Mission (SRTM), DEM-derived catchments, drainage networks research area. most important applied area...

Abstract. Mountainous landscapes often feature alluviated valleys that control both ecosystem diversity and the distribution of human populations. Alluviated, flat valley floors also play a key role in determining flood hazard these landscapes. Various mechanisms have been proposed to spatial width floors, including climatic, tectonic, lithologic drivers. Attributing one drivers observed floor ...
