Landslide

check dams

Natural environment; Landslide

Small sediment storage dams built in the channels of steep gullies to stabilize the channel bed. A common use is to control channelized debris flow frequency and volume. Check dams are expensive to ...

colluvium

Natural environment; Landslide

A general term applied to loose and incoherent deposits, usually at the foot of a slope or cliff and brought there chiefly by gravity.

debris basin

Natural environment; Landslide

A large excavated basin into which a debris flow runs or is directed, and where it quickly dissipates its energy and deposits its load. Abandoned gravel pits or rock quarries can often be ...

delta-front landsliding

Natural environment; Landslide

Underwater landsliding along coastal and delta regions due to rapid sedimentation of loosely consolidated clay, which is low in strength and high in pore-water pressures.

digital elevation model (DEM)

Natural environment; Landslide

A digital elevation model is a digital file consisting of terrain elevations for ground positions at regularly-spaced horizontal intervals.

digital terrain model (DTM)

Natural environment; Landslide

A Three-dimensional model of digital elevation data (DEM) for cartographic representation. Terrain models are often displayed as grids, superimposed over topography maps to illustrate peaks and ...

drawdown

Natural environment; Landslide

Lowering of water levels in rivers, lakes, or underground aquifers due to pumping or artesian flow. Drawdown may leave unsupported banks or poorly packed earth that can cause landslides.
