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 ...
The objects may be arranged randomly or systematically. They can be natural, as with a drainage pattern of a river, or man-made, as with the squares formed from the United States Public Land Survey System. Typical adjectives used in describing pattern are: random, systematic, circular, oval, linear, rectangular, and curvilinear to name a few.
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
Four minor kinds of drainage patterns also can be created: radial patterns, annular patterns, centripetal patterns and parallel patterns. Radial patterns are characterized by flow of water outward from a central point, such as down a newly formed cinder volcano cone or an intrusive dome. Annular patterns form on domes of alternating weak and ...
The radial flow passes through a vertical, cylindrical, cross-section representing the hydraulic equipotential of which the surface diminishes in the direction of the axis of intersection of the radial planes where the well is located.

A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.

The radial pattern of the main deeply glaciated valleys is thought to reflect the original radial pre-glacial drainage pattern of the massif. At various times, the peaks were either completely covered by ice or formed protruding nunataks .
