Flood is one of the natural disaster known to be part earth biophysical processes, which its occurrence can devastating; due mostly anthropogenic activities and climatological factors. The aim research identify map extent at impact flood intense rainfall rise in water study area using geospatial techniques specific objectives are carry out terrain analysis generate indicator maps area. analyzed...

In this paper, based on the study of palaeogeomorphology restoration methods, drilling, logging, seismic data and regional structural history are analyzed, pre-sedimentary Xujiahe Formation in Sichuan Basin is restored by means well-seismic combination “fill blanks” as its theoretical basis. The shows that “low west, high east, low north, south”, “the south steep, north slow”. According to dist...

Slope stability analysis is traditionally carried out with the ultimate equilibrium methods. In these approaches, global assessment of slope obtained through evaluation factor safety. The strength parameters that allow resistant forces along hypothetical slip surface are considered unique and constant. shape stress-strain curve soil may substantially affect mass over, particularly in case poten...

in this paper, effects of the cross shore and groyne wall slopes on flow parameters around an impermeable groyne were considered using a three-dimensional numerical cfd model (i.e., fluent). the k-ε turbulence model was used to evaluate the reynolds stresses. the model was first applied to a vertical groyne on a flat bed and the model results were compared with the relevant experimental data. t...

Deadwood plays important roles in forest ecosystems by storing carbon, influencing hydrology, and provisioning countless organisms. Models for these processes often assume that deadwood does not move and ignore redistribution that occurs when trees fall. To evaluate the effects of treefall, we provide the first direct estimates for the magnitude, direction, and drivers of deadwood movement in a...

The relation of three main effects of eye-position on perceived direction was investigated using a method of hand pointing in the horizontal plane: (1) Retinal eccentricity is overestimated with respect to the fovea by a constant factor of 2.6 degrees; (2) an extraretinal signal induces a shift in perceived visual direction (slope 0.12) that is opposite to the direction of eccentric gaze; and (...
