Corrigendum: Experimental study on landslides of loose sediment slope induced by stream bed incision
In the published article, there was an error in Figure 1 as published. Due to negligence, ‘Landslide site’ mistakenly written stie’. The corrected and its caption appear below.The authors apologize for this state that does not change scientific conclusions of article any way. original has been updated.
Thirteen species of planktonic foraminifera collected with vertically stratified zooplankton tows in the slope water, Gulf Stream cold core ring, and northern Sargasso Sea show significant differences in their vertical distributions in the upper 200 meters of these different hydrographic regimes. Gulf Stream cold core rings may be responsible for a southern displacement of the faunal boundary a...
Relationships between some properties of frog calls and body size are widely recognized. However, generality across call components and diverse faunas, and sources of deviation, remain poorly tested. Using 116 east Australian frog species, we tested the relationship between three call traits and body size, and the effects of taxonomic family and calling habitat. Call dominant frequency (DF) has...
During recent years, landslide incidence has been increased in different areas with different reasons like change in land use and road introduction. It is necessary to research and survey that’s creation factors and identity sensitive areas to prohibit of probable damages. For this reason, This study were carried out in Northern of Tehran watershed with about 42.14 km2 area. In order to landsli...
In this study, using the frequency ratio (FR) model, an attempt has been made to identify areas with high groundwater potential of the Sira catchment. Effective factors for preparing groundwater potential map including slope aspect, slope percentage, slope length (LS), Elevation, stream power index (SPI), topographic wetness index (TWI), plan curvature, distance to rivers, distance to roads, di...
35 36 New high resolution multibeam data in the Gulf of Bothnia reveal for the first time the 37 subglacial environment of a Bothnian Sea Ice Stream. The geomorphological record suggests 38 that increased meltwater production may have been important in driving rapid retreat of 39 Bothnian Sea ice during deglaciation. Here we apply a well-established one-dimensional 40 flowline model to simulate...
Multivariate statistical techniques were used on data from two cruises to Gulf Stream warm core rings to reveal patterns and relationships between phytoplankton species abundance and environmental parameters. Principal component analysis (PCA) was performed on each cruise separately and on the combined data to help delineate groups of stations, depths, and species. A ring center station with hi...
A simple analytic model is presented relating local sediment transport capacity to variance in the transverse shear stress distribution in a stream channel. The model is used to develop a physically based conceptual model for the initiation of meandering in straight, bedloaddominated streams as a result of a feedback mechanism. The feedback maximizes the crosssectional shear stress variance and...
