erodibility

However, the critical factor that determines whether a stream will meander or braid is bank erodibility.

Differences in the erodibility of the volcanic rocks of the area are the main factor for the pillars creation.

The unit plot is defined as the standard plot condition to determine the soil's erodibility.

They were soil color, organic content, soil structure, drainage, erodibility, and nature of subsoil.

The soil erodibility factor K can be approximated from a nomograph if this information is known.

Removing riparian vegetation increases the erodibility of stream banks, and can also speed the rate of channel migration.

The erodibility index is used in conjunction with conservation compliance and the Conservation Reserve Program.

Because of its erodibility and incompetent nature the Ligérian forms slopes beneath the much more resistant Angoumian cliffs.

At smaller geographical scales it is physiographic variables (those describing erodibility and erosivity) which best explain the spatial variations of soil erosion.

They are also very common in agricultural areas because sustained agriculture depletes the soil of much of its organic content, increasing the erodibility of the soil.

The resistance of the limestone and the greater erodibility of the underlying rock has resulted in the upper part of the mesa being mostly surrounded by precipitous walls.

In the equilibrium theory, meanders decrease the stream gradient until an equilibrium between the erodibility of the terrain and the transport capacity of the stream is reached.

Ranger Uranium Mine in Northern Australia showed a significant increase in erodibility of lands when in contact with materials treated from chemical mining (Riley 1995).

A review by one geographer who has contributed to the development and application of indices of soil erodibility (Bryan, 1978) includes the aphorism (Bryan, 1979, p. 207):

The parameters K, m and n are not necessarily constant, but rather may vary as functions of the assumed scaling laws, erosion process, bedrock erodibility, climate, sediment flux, and/or erosion threshold.

The hardness or 'erodibility' of sea-facing rocks is controlled by the rock strength and the presence of fissures, fractures, and beds of non-cohesive materials such as silt and fine sand.

However, the main underpinning causes of this erosion appear to be methods of management and land tenure rather than erosivity and erodibility (section 6.2.2), especially as sugar-cane provides a protective cover for most of the year.

A wind erosion equation is an equation used to design wind erosion control systems, which considers soil erodibility, soil roughness, climate, the unsheltered distance across a field, and the vegetative cover on the ground.

In the southeast, soils have a medium risk of erosion, and soils around Powell Butte and the Boring Lava Domes have "an extremely high erodibility factor and are sensitive to ground disturbance".

As Zachar (1982) has described, the poor cohesiveness of loess soils, due to the paucity of binding colloids, means that they are characterised by high erodibility which is made worse by leaching that rapidly removes cations like calcium and magnesium.

This bill allowed the termination of contracts after five years, with the exception of filterstrips, waterways, strips adjacent to riparian areas; lands with an erodibility index of over 15; and other lands that the Secretary deems to be highly sensitive [7].

Whitlow's comparison (Fig. 7.3) between the occurrence of actual erosion, as deduced from aerial photographs, with a survey of potential erosion hazards based on environmental factors such as rainfall erosivity, soil erodibility and slope, indicates that there is poor agreement between the two.

The erosion index (EI, also called the erodibility index) is created by dividing potential erosion (from all sources except gully erosion) by the T value, which is the rate of soil erosion above which long term productivity may be adversely affected.
