extended abstract 1. introduction neo-tectonics is the study of horizontal and vertical motions of earth’s crust originating from the late periods of neogen and quaternary. many researchers have defined tectotecnic as “the beginning of earth’s crust motions after the earliest orogenic phase” (stipancikova et al., 2008, p. 68). since there is no possibility of having access to the old seismic re...

abstract: the aim of this study is analysis of drainage basins neotectonic in the north slope of bozqoosh mountains by geomorphological methods. to attain this aim, it used of field observation, areal photographs and five geomorphic indexes in 20 basins of the north slope of bozqoosh mountains. indexes were calculated by topography maps (1: 50000), geological maps (1: 100000) and areal photogr...

Scientists have long assumed that the physical structure and condition of stream and river channels have pervasive effects on biological communities and processes, but specific tests are few. To investigate the influence of the stream-reach geomorphic state on in-stream habitat and aquatic macroinvertebrate communities, we compared measures of habitat conditions and macroinvertebrate community ...

Significant advances have been made towards understanding the dynamics of geomorphic systems through the development of new concepts. In the last two decades, these developments were partly guided by the change in the scale of geomorphic analysis from local (landform) to regional (landscape) scale and partly due to the emergence of new scientific tools and quantitative models. The process-based...

abstract tectonic, plays a key role in the evolution of morphology and can be distinguished with morphotectonic, rivers and structural parameters. an analysis of morphometric parameters illustrates that the development of them is associated with faults activities and rocks resistance. morphotectonic analysis also supplies seismotectonic setting for a region. for appropriate and survey tectonic ...

geomorphic indexes are useful tools in identification of evaluation in trace of tectonic activity (relatively rapid or even slow). since the drainage network morphology and behavior changes resulting from tectonic activity are very sensitive it seems to be evidence such as crossing the fault line and changes river bed affected by the neotectonic activities in basin. thus, for understanding and ...

Geomorphic systems are typically nonlinear, owing largely to their threshold-dominated nature (but due to other factors as well). Nonlinear geomorphic systems may exhibit complex behaviors not possible in linear systems, including dynamical instability and deterministic chaos. The latter are common in geomorphology, indicating that small, short-lived changes may produce disproportionately large...
