The results indicate that the size and density of defects increase when grain sizes and projected masses are enhanced, and the surface becomes more damaged. As the mass and size of the sand grains increase, the roughness and surface damage increase and reach the values of 41.2渭mdocumentclass[...
In debris flow, water characterizes the downslope movement of the diverse material, including boulders and sand size materials. The last one is the earthflow in which the small size water-saturated materials move downslope at a variety of speeds. ...
摘要: Mass transport inside the oscillatory bottom layer near the sea bottom is studied for three-dimensional wave motion. Influence on the transport of fine and coarse sand and significance to the sea bottom morphology are presented.关键词:...
(Kaiser, Mackay, & Gale, 1986; Goel, Jethwa, & Paithankar, 1995a). N is found to be complimentary to the Q-system. Correlations (inChapter 7) based on N can first be used to identify the ground conditions and then the rating forSRF, because the ground condition and degree of ...
In a mixed Mytilus edulis/Lanice conchilega community on the Swinnplate sand flat behind Spiekeroog Island (southern North Sea), net seasonal fluxes of sand and mud were determined by combining measurements of topographic elevations, sediment dry bulk density, and mud contents for 7 to 8-month...
location, shape and speed of the body. Large masses are measured in tonnes while small masses are measured in grams. Examples of Masses of Objects Examples of Masses of Objects Object Mass in kilogram (kg) Electron A fine grain of sand A pea An apple A medium-sized car Earth Sun 10 -...
45. Q can then be estimated as a function of u∗ and u∗t for mono-sized, dry or wet, loose soils. In fact, these are saltation models, based on experimental data of mono-sized sand transport, which have not been tested for dust particles or mixed grain sizes. However, in ...
of sand surfaces than on surfaces with pebbles, (iii) the exponential model underpredicted mass flux in the near-bed region in the case of sandy surfaces, whereas in the case of pebble surfaces, the departures from the model were insignificant, and (iv) a pebble cover with a low density ...
The effect of water supply on total mass and yield of broccoli (Brassica oleracea L. var. italica, 'Emperor') was examined in an experiment carried out in a microplot field installation on three soil types: Gleyic Cambisol (sand) and Eutric Fluvisol (flood-plain loam) in spring and fall...
