flow — A category of mass movement processes, associated sediments (flow deposit) and landforms characterized by slow to very rapid downslope movement of unconsolidated material which, whether saturated or comparatively dry, behaves much as a viscous … Glossary of landform and geologic terms
flow control — Measures designed to adjust the flow of traffic into a given airspace, along a given route, or bound for a given aerodrome, so as to ensure the most effective utilization of the airspace (ICAO). ATC (air traffic control) may apply restrictions to … Aviation dictionary
artesian flow — Flow through a confined aquifer where the elevation of the overlying aquiclude is locally depressed so that the entire aquifer is saturated and the flow is under hydrostatic pressure. Some maze cave development in cavernous limestones may… … Lexicon of Cave and Karst Terminology
Groundwater flow equation — Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer. The transient flow of groundwater is described by a form of the diffusion equation, similar … Wikipedia
Debris flow — Scars formed by debris flow in great Los Angeles during the winter of 1968 1969. The photograph was taken within several months of the debris flows occurring. A debris flow is a fast moving, liquefied landslide of unconsolidated, saturated debris … Wikipedia
subcutaneous flow — Lateral and vertical flow that occurs within the epikarst zone under saturated conditions. Lateral flow distances can exceed hundreds of meters and several meters per day while vertical within discrete percolation drains (subcutaneous drains)… … Lexicon of Cave and Karst Terminology
debris flow — The mass movement process, associated sediments (debris flow deposit), or resultant landform characterized by a very rapid type of flow dominated by a sudden downslope movement of a mass of rock, soil, and mud (more than 50% of the particles… … Glossary of landform and geologic terms
debris flow — ALASKA VOLCANO OBSERVATORY GLOSSARY A mixture of water saturated rock debris that flows downslope under the force of gravity (also called lahar or mudflow). GLOSSARY OF VOLCANIC TERMS A type of mass flow comprising a dense, cohesive, flowing… … Glossary of volcanic terms
overland flow — water running over the surface of the land into a river channel or body of water. May occur due to: impermeable rock surfaces, saturated soils, rainfall intensity exceeding infiltration rate, snow/ice melt and compacted soils … Geography glossary
debris flow — /ˈdɛbri floʊ/ (say debree floh) noun a moving slurry of soil mixed with trees, rock fragments, etc., that are in its path, generated when a hillside becomes saturated with water, as from heavy rain or melting snow, and collapses; mudflow …
