Parallel drainage pattern. A parallel drainage system occurs on elongate landforms like outcropping resistant rock bands), typically following natural faults or erosion (such as prevailing wind scars). The watercourses run swift and straight, with very few tributaries, and all flow in the same direction.
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 ...
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.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
When drainage patterns follow these paths, it creates angular, dendritic patterns within topography. Lack of soil cover in these dry regions gives joints maximum control over drainage systems resulting in angular patterns, striking topography, and steep slopes.
An asymmetric forked drainage pattern forms during lateral growth of a fold. The direction along which drainage channels 'bend away' from the fold crest is the direction of lateral fold growth(fig. 7) [6] [15] [26]. Imagine the following situation: at an early stage of folding and near the fold tip, river flows approximately along the fold ...
Yazoo stream [1]. A Yazoo stream (also called a Yazoo tributary [2]) is a geologic and hydrologic term for any tributary stream that runs parallel to, and within the floodplain of a larger river for considerable distance, before eventually joining it.
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.
