For each experimental condition, measurements of velocity field and scouring profile on the embankment were repeated for the cases with and without vegetation mat, respectively, to assess the efficiency of the vegetation mat in protecting the embankment.
A dramatic reduction in soil loss rate was observed in the cases with the vegetation mat installed.
The hydraulic stability of the high-water revetment with and without vegetation mat was tested in both laboratory-scale hydraulic experiments, as well as prototype-scale experiments.
Through three case studies, the possibility of integrating new aspects into textile architecture, such as vegetation mats, aerogel granules insulation or algae cultures, to enhance the performance of the textiles is presented.
Assuming a clear atmosphere that gives a view of the surface, these guys estimate the colour of alien Earths based on the percentage of surface covered in water, tree-like vegetation, bacterial mats, endoliths, which live inside rocks, and so on.
It is found more often in open, deeper portions of marshes, generally in wetlands with considerable open water and large stands of island-like vegetation and/or large mats of floating vegetation.
During this period the landscape was dominated by a coastal mosaic vegetation including dune mats, coastal scrub and salt marshes on the dunes and backdunes, with chaparral and oak woodland growing in the valley plains and foothills.
As trail use intensifies, denudation of vegetation and organic mats reduces insulation of permafrost soils, thereby causing erosion, thaw subsidence, and ponding of water.
Caroline Island is heavily vegetated, and most islets possess three ringed zones of vegetation: an outermost herb mat, typically composed mainly of Heliotropium anomalum; an inward zone of shrub, primarily Heliotropium foertherianum; and a central forested region, typically dominated by groves of Pisonia grandis trees.
The lake begins to fill by the development of a floating mat of vegetation next to the shore.
They would don goggles and dust masks, duct-tape cardboard to their forearms and shins for protection, and "crawl" over the nearly solid mat of vegetation with soil augers in hand.
