Burrow systems of earthworms contained in artificial cores were analysed through X-ray computed tomography and 3D skeleton reconstructions. Gas diffusion experiments were carried out on these cores to characterize soil transfer properties associated with the different burrow systems. Three types of cores were studied: cores in which Aporrectodea nocturna, an anecic earthworm was introduced (tre...

meanders are among the important characteristics of some rivers that flow in semi-arid regions. swift displacement along the river's flow, change in the location of the central ridge and bank erosion leateral erosion are resulted from making meander in the river's flow. meanders in river courses on north east slopes of sahand (located in 46ëš 43ì to 47ëš 15ì e and from 36ëš 05ììì...

Channel migration and resultant meander movements are the two important fluvial processes found in riparian environment of a river basin. The present research explores changing nature geometry Raidak-I River Himalayan foothill region using geospatial tools. study incorporated Landsat data (satellite imageries) for years 1972, 1980, 1988, 2004, 2012 2021 whole has been segmented into five period...

Sedimentological and architectural features of meandering subtidal channels are relatively unexplored, their deposits commonly investigated based on facies models set up for intertidal channels. The Venice Lagoon (northern Adriatic Sea, Italy) is affected by a micro-tidal regime hosts dense network active buried tidal It represents an excellent natural laboratory to improve the current knowledg...

Models of the sedimentary architecture submarine channel-levee systems and their formative flow processes are predominantly based on studies from low latitude settings. Here, we integrate high-resolution seismic reflection, bathymetry GLORIA side scan data to document interpret a series ultra-high (72–76°N) that feed lobe complexes off Greenland margin. We demonstrate channel-fills dominated by...

Turtles are among the most threatened vertebrate groups, and reconstruction of population distributional trends can be important for evaluating their status defining conservation targets. Using a two-phase modeling approach along with occurrence records field surveys, our objectives were to: estimate potential current distributions wood turtle (Glyptemys insculpta), semi-terrestrial fluvial spe...

An analysis of the sedimentary fill a foreland basin can provide information on relative effect tectonics, base-level fluctuations and climate during development. This study analyzes fluvial strata from upper Cedar Mountain Naturita formations mid-Cretaceous Utah (USA) to determine effects spatial location within planform architecture. The results document consistent architecture across distal ...

Deep-water channels can be bound by overbank deposits, resulting from overspilling flows, which are often ornamented with sediment waves. Here, high-resolution bathymetry, backscatter, and 2D 3D seismic data integrated to discern the controls on flow processes areas of Hikurangi Channel. Qualitative interpretation quantitative analyses wave morphologies distributions conducted through shallowes...

The movement patterns of deep-sea bioturbational fauna are believed to be the result organism’s interactive response perceived spatial distribution nutritional resources on seafloor. To address this hypothesis, we examined paths Echinocrepis rostrata -a common epibenthic bioturbator echinoid in northeast Pacific Ocean- through fractal analysis order characterize how they cover seafloor during f...

the study area is the rahmat anticline. this is located in fars province (sw fold simple zagros belt). the aims of this study are morphotectonic studies and structural analysis in several parts of area. for this purpose: 1) morphotectonic indices, drainage basin shape index (bs), mountain front sinuosity index (smf) and valley floor width – height ratio (vf) were measured by digital elevation m...
