The jet erosion test (JET), or jet index test, is a method used in geotechnical engineering to quantify the resistance of a soil to erosion. The test can be applied in-situ after preparing a field site, or it can be applied in a laboratory on either an intact or a remolded soil sample .
Pantone innovated GIS methods to identify the habitat of this rare and endangered species based on elevation, slope, aspect and soil type. In addition to his ecological and environmental research, Pantone has been involved in the preservation of human cultures, being the cofounder of an indigenous rights organization.
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.
A minority of farmers in the Texas High Plains region are looking to organic and regenerative techniques to keep their soil healthy year round, despite a dry climate.
Rephotography continues to be used by the scientific world to record incremental or cyclical events (of erosion, or land rehabilitation, [8] or glacier flow [9] for example), or to measure the extent of sand banks in a river, or other phenomena which change slowly over time, [10] and in gathering evidence of climate change. [11] [12] [13]
Most soil erosion models consider only soil erosion by water, however a few aim to predict wind erosion. Models which consider tillage erosion are rare. Also soil erosion models have been more commonly developed for use on agricultural landscapes, rather than on naturally vegetated areas (such as rangeland or forests).
On September 13, 1933, the Soil Erosion Service was formed in the Department of the Interior, with Bennett as chief. The service was transferred to the Department of Agriculture on March 23, 1935, and was shortly thereafter combined with other USDA units to form the Soil Conservation Service by the Soil Conservation and Domestic Allotment Act ...
From the change in diameter of the hole over time, the rate of erosion can thus be plotted against applied hydraulic shear stress and fit to the following equation: [1] [4] = where E r is the rate of erosion over time, k d is the soil erodibility, and τ c is the critical shear stress for erosion.
