  2. A-Jacks - Wikipedia

    en.wikipedia.org/wiki/A-Jacks

    The advantage of A-Jacks over other hard armoring solutions is the comparatively large area available in the interstitial spaces for native vegetation to take root, ultimately helping to restore the stream bank to a more natural state while continuing to protect against erosion.

  3. Landslide mitigation - Wikipedia

    en.wikipedia.org/wiki/Landslide_mitigation

    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.

  4. Tetrapod (structure) - Wikipedia

    en.wikipedia.org/wiki/Tetrapod_(structure)

    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 ...

  5. Erosion control - Wikipedia

    en.wikipedia.org/wiki/Erosion_control

    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.

  6. Dolos - Wikipedia

    en.wikipedia.org/wiki/Dolos

    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.

  7. Armor (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Armor_(hydrology)

    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.

  9. Level spreader - Wikipedia

    en.wikipedia.org/wiki/Level_spreader

    Illustration of a level spreader designed to infiltrate road drainage. A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent applications such as drainage for roads and highways.
