The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Successful design of the slope requires geological information and site characteristics, e.g. properties of soil/rock mass, slope geometry, groundwater conditions, alternation of materials by faulting, joint or discontinuity systems, movements and tension in joints, earthquake activity etc. [4] [5] The presence of water has a detrimental effect ...
d = run Δh = rise l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent.
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.
Senate Majority Leader Chuck Schumer said Sunday that he sent a letter to Mayorkas urging Homeland Security to deploy special drone-detection technology, such as a 360-degree radar called the Robin.
“Fly 1,500 miles home with me to vote,” Kayla Iutzwig says in a TikTok video showing her packing a suitcase and heading to the airport. The 21-year-old lives in Los Angeles but is registered ...
Heather Locklear is opening up about her favorite memories from filming the sitcom Spin City — and sharing what was different about working with Michael J. Fox versus his replacement in the ...
It's the point at which the soil cannot sustain any additional load without undergoing continuous deformation, in a manner similar to the behaviour of fluids. Certain properties of the soil, like porosity, shear strength, and volume, reach characteristic values. These properties are intrinsic to the type of soil and its initial conditions.
