Armour of basalt blocks. In hydrology and geography, armor is the association of surface pebbles, rocks or boulders with stream beds or beaches.Most commonly hydrological armor occurs naturally; however, a man-made form is usually called riprap, when shorelines or stream banks are fortified for erosion protection with large boulders or sizable manufactured concrete objects.
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
The Drainage anti-slide pile (DASP) is a reinforced concrete structure with a hollow upper section and a solid lower section, designed to resist slope deformation. [ 2 ] [ 3 ] The hollow part is filled with compacted, high-permeability gravels and can drain water via a vertical drain-pipe or sub-horizontal pipes connected to the slope surface.

Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod . Weighing up to 8 tonnes (8.8 short tons ), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.
Permeable interlocking concrete pavements are concrete units with open, permeable spaces between the units. [ 28 ] : 2 More recently manufacturers have introduced styles with smaller joint allowing for better ADA compliance and still capturing a significant amount of stormwater.
Plant roots can anchor into cracks in bedrock through soil mass and can pass through weak areas to more stable soils to provide interlocking long-fibre binders in weak soil blocks. [7] It requires 137 tons of forces to break a soil mass reinforced by linden, which 130 tones are used to break the roots and only 7 tons are required to lead to ...
