Three types of erosion-status sites (stable, eroding and aggrading) were identified using reconnaissance surveys, and then the corresponding soil samples were collected and analyzed.
Areas geomorphologically more stable withstood erosion much longer as residual landforms with disparate environmental conditions from those found in the pediplains [ 20, 22], which can act as barriers to gene flow for taxa associated with such residual habitats, thus creating a sky-island setting [ 23- 25].
The results showed that the single Fe2B phase coating hardly had stable anti-erosion capability when the coating thickness was less than 20 μm under the continuous impacts.
For the bilayer boride coating composed of top phase FeB and bottom phase Fe2B, the whole coating began to show the stable anti-erosion performance with top FeB phase coating thickness of 120 μm from the standpoint of maximum surface tensile stress reduction.
The landscape has been (on the whole) stable, but the erosion rate varies spatially according to microclimate, geology, and surface composition.
A new testing facility that ensured stable and reproducible erosion testing with sand velocities and concentrations up to 250 m/s and 5 wt% in air, respectively, was built at IMI. Special rig design features allowed accurate sand consumption monitoring during each test.
For Phase 2, vegetation cover must be established in stable areas without erosion.
For example, he said, on a beach that receives a steady influx of sand, "you can have marginal erosion or stable or even accreting shorelines".
Those on the left have pushed the idea as a means of fighting poverty and the steady erosion of stable jobs with pensions and benefits, while the right envision it as a way to streamline the bureaucratic welfare systems.
High cosmogenic nuclide concentrations also show that the constituents of the Whippoorwill Formation experienced long exposure at a stable landscape surface with erosion rates of 1 2 m/Ma.
