Falls are abrupt movements of masses of geologic materials, such as rocks and boulders, that become detached from steep slopes or cliffs. Separation occurs along discontinuities such as fractures, joints, and bedding planes, and movement occurs by free-fall, bouncing, and rolling.

Cohesive soils are fine-grained, low-strength, and easily deformable soils that have a tendency for particles to adhere. The soil is classified as cohesive if the amount of fines (silt and clay-sized material) exceeds 50% by weight (Mitchell and Soga 2005 ). Examples of cohesive soils include sandy clay, silty clay, clayey silt, and organic clay.Geology of the Charleston phosphate area, South Carolina; a detailed study of the area from which phosphate rock was first produced in this country. ... hardpan in a soil with red mottling_ _____-Following 74 9.

The upper zone is mostly used for water supply in southern Mobile, southern Baldwin, and southwestern Escambia Counties, Ala., because the lower zone contains much clay in these counties, and, accordingly, yields less water.

Hardpan, also known as caliche, is a surface or shallow layer in a soil or sediment in which the grains have been cemented together. Depending upon the degree of cementation, the layer might be thin and easily broken with a hammer, or it could be two or more meters thick and completely cemented. Jutras, P., 2016.
