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.
This flooding process is performed on the gradient image, i.e. the basins should emerge along the edges. Normally this will lead to an over-segmentation of the image, especially for noisy image material, e.g. medical CT data. Either the image must be pre-processed or the regions must be merged on the basis of a similarity criterion afterwards.
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.
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 ...
The two stage drainage ditch is classified as a 'surface' sustainable drainage system, contrary to a sub-surface system. The two stage drainage ditch is a modification of the land whereby grass benches which serve as floodplains are formed within the land of the watershed of the water system, shown in the diagram to the right.

A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt's drainage equation. A well known steady-state drainage
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 ...
Consider two patterns made of parallel and equidistant lines, e.g., vertical lines. The step of the first pattern is p, the step of the second is p + δp, with 0 < δp < p. If the lines of the patterns are superimposed at the left of the figure, the shift between the lines increases when going to the right.
