Channel patterns are found in rivers, streams, and other bodies of water that transport water from one place to another.Systems of branching river channels dissect most of the sub-aerial landscape, each in a valley proportioned to its size.
[1] bore 1. A steep-fronted wave formed by the convergence of two tidal bulges or by the constriction of an incoming tide as it travels up a river, firth, or narrow bay, temporarily reversing the direction of the current. [4] 2. A deep, man-made hole or shaft drilled into the ground, e.g. in mining, or for digging a well or tunnel.
Ashlar (/ ˈ æ ʃ l ər /) is a cut and dressed stone, worked using a chisel to achieve a specific form, typically rectangular in shape. The term can also refer to a structure built from such stones. [1] Ashlar is the finest stone masonry unit, and is generally rectangular . It was described by Vitruvius as opus isodomum or trapezoidal.
Two adjacent vermiculated blocks showing rather different interpretations of the pattern. The most common variation of rustication is the smooth-faced, where the external face of the block is smooth, as in ashlar, and differs from that only by the cutting in at the joints; this became increasingly popular, and is now the most commonly seen type.
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population. [ 1 ]
Radial drainage pattern The radial drainage network of Dogu’a Tembien in Ethiopia. In a radial drainage system, the streams radiate outwards from a central high point. Volcanos usually have archetypal features on which this commonly develops are modest or hard domes pattern develops when streams flow in many general directions (meaning quite ...
Headward erosion creates three major kinds of drainage patterns: dendritic patterns, trellis patterns, and rectangular and angular patterns. Dendritic patterns form in homogenous landforms where the underlying bedrock has no structural control over where the water flows. They have a very characteristic pattern of branching at acute angles with ...
Pattern detection via the identification of such geographical clusters is a very simple and generic form of geographical analysis that has many applications in many different contexts. The emphasis is on localized clustering or patterning because this may well contain the most useful information.
