Highly erodible soils definition

Highly erodible soils means soils (excluding vegetation) with an erodibility index (EI) from sheet and rill erosion equal to or greater than eight. The erodibility index for any soil is defined as the product of the formula RKLS/T, where K is the soil susceptibility to water erosion in the surface layer; R is the rainfall and runoff; LS is the combined effects of slope length and steepness; and T is the soil loss tolerance.

Highly erodible soils means those soils with a slope greater than 15 percent; or those soils with a K value greater than .35 and with slopes greater than 5 percent.

Highly erodible soils means very unstable soils that are generally described as Sodosols with hard setting, fine sandy loam to silty clay loam surfaces (solodics, solodised solonetz and solonetz) or soils with a dispersible layer located less than 25 cm deep or soils less than 25 cm deep.

Examples of Highly erodible soils in a sentence

  • Highly erodible soils are those that are easily carried by water and, to a lesser extent, by wind.

  • Highly erodible soils include those soils with a slope greater than 15% or those soils with a K value greater than .35 and with slopes greater than 5%.

  • The Figure contains the following information:• The proposed Facility and Project Area; • Undeveloped or abandoned lands (vacant fields, wood lots, etc.); • Wildlife areas, nature preserves, and other conservation areas; • Bodies of water, including but not limited to, streams, drainage channels/ditches, wetlands, reservoirs, lakes, and ponds; and• Highly erodible soils and slopes 12 percent and greater.

  • Erosion control blankets and turf reinforcement mats must be considered for: Fill slopes greater than 10 feet high Ditch slopes greater than 10 percent Highly erodible soils Fluctuating water levelsHigh ditch flows High sheet flow Standard seeding and mulching will not withstand anticipated runoffAround high quality water bodies.ECBs, TRMs, or an equivalent erosion control practice is recommended for most slopes steeper than 1V:3H (3:1), depending on soil type.

  • Highly erodible soils within the basin have produced high impact levels of fine sediments in the lake and mass wasting in areas of the watershed.
