Gravel is another common ingredient in erosion prevention measures. The mine grinds this rock into small stones and sells it as gravel. The gravel is layered on the surface of dams, fences and boards used to prevent erosion. The gravel gives the soil something to catch onto, holding it in the presence of flowing water.

Water erosion Sea wave erosion is accomplished primarily by hydraulic pressure, the impact of waves striking the shore, and by the abrasion (wearing, grinding, or rubbing away by friction) by sand and pebbles agitated incessantly by the water (see wave-cut platform).

The movements of ice, water, and wind cause these changes. These movements break down landforms, carry away the pieces, and deposit them in new places – creating new landforms in the process. In addition to eroding the edges of a valley, the great weight of a glacier can crush surface rocks underneath it.

Water erosion is very simplistically speaking caused by rainfall, river flow, waves (wave action, hydraulic action and abrasion), corrosion, glacier movement, thawing, etc., while wind erosion is caused by wind picking up loose particles (deflation) that batter the ground as they fly by (abrasion), causing additional …

Wind Eroded Arid Landforms – Deflation basins, Mushroom rocks, Inselbergs, Demoiselles, Demoiselles, Zeugen , Wind bridges and windows. Depositional Arid Landforms – Ripple Marks, Sand dunes, Longitudinal dunes, Transverse dunes, Barchans, Parabolic dunes, Star dunes and Loess.

Water drains more quickly through gravel than it does through most types of soil, so using rocks to divert water helps mitigate standing water in landscapes and on walkways. Puddles form less readily on gravel-covered pathways and borders than they do on soil surfaces.

There are many methods that can be used to stabilize a rock slope. These include altering the slope geometry, installing drainage, adding reinforcement, or a using combinations of these methods.

The most important process producing creep, aside from direct gravitational influences, is frost heaving: as interstitial water freezes, surface particles are forced up and out perpendicular to the slope; when let down by melting, these particles are drawn directly downward by gravity and are thereby gradually moved …

1. Foundation Cracks. One of the most obvious signs that you’ve got a problem with foundation sinking or settling is finding noticeable cracks in your foundation walls. However, not all foundation wall cracks are bad – some are, in fact, normal.
