ChannelIn hydrologic terms, also known as Watercourse; an open conduit either naturally or artificially created which periodically, or continuously contains moving water, or forms a connecting link between two bodies of water. River, creek, run, branch, anabranch, and tributary are some of the terms used to describe natural channels. Natural channels may be single or braided. Canal and floodway are some of the terms used to describe artificial channels.Channel InflowIn hydrologic terms, water, which at any instant, is flowing into the channel system form surface flow, subsurface flow, base flow, and rainfall that has directly fallen onto the channel.Channel LeadIn hydrologic terms, an elongated opening in the ice cover caused by a water current.Channel RoutingIn hydrologic terms, the process of determining progressively timing and shape of the flood wave at successive points along a river.Channeled High WindsIn mountainous areas or in cities with tall buildings, air may be channeled through constricted passages producing high winds. Santa Ana winds and winds through passes from the cold Alaskan interior to the sea are examples of these winds. Channeled high winds are local in nature but can be extremely strong. These winds generally occur in well-defined areas.ChannelizationIn hydrologic terms, the modification of a natural river channel; may include deepening, widening, or straightening.Filament ChannelA broad pattern of fibrils in the chromosphere, marking
where a filament may soon form or where a filament recently
disappeared.Forced ChannelingChanneling of upper winds along a valley's axis when upper winds are diverted by the underlying topography. Compare pressure-driven channeling.Lightning ChannelThe irregular path through the air along which a lightning discharge occurs.
A typical discharge of flash between the ground and the cloud is actually a composite flash
which is composed of several sequential lightning strokes, each of which is initiated by a leader
and terminated by a return streamer.Outflow ChannelIn hydrologic terms, a natural stream channel which transports reservoir releases.Pressure-driven ChannelingChanneling of wind in a valley by synoptic-scale pressure gradients superimposed along the valley's axis. Compare forced channeling.
