What is the meaning of Obsequent River?
What is the meaning of Obsequent River?
/ (ˈɒbsɪkwənt) / adjective. (of a river) flowing into a subsequent stream in the opposite direction to the original slope of the land.
What is an obsequent stream?
obsequent stream in American English (ˈɑbsɪkwənt) Geology. a stream flowing in a direction opposite to that of the dip of the local strata. Compare consequent stream.
What does the term fluvial mean?
in a stream or river
Definition of fluvial 1 : of, relating to, or living in a stream or river. 2 : produced by the action of a stream a fluvial plain.
What does Insequent mean?
Definition of insequent of the course of a stream. : apparently uncontrolled by the associated rock structure.
What is subsequent drainage?
Subsequent drainage The term “subsequent river” refers to streams that have emerged after the initial stream (Consequent River) After the primary drainage pattern has been created, a tributary stream is eroded along an underlying band of non-resistant rock.
What is drainage pattern in geography?
Drainage Pattern: It refers to the system of flow of surface water mainly through the forms of rivers and basins. The drainage system depends upon factors such as slope of land, geological structure, amount of volume of water and velocity of water.
What is dendritic drainage pattern in geography?
The dendritic pattern develops where the river channel follows the slope of the terrain. The pattern develops in areas where the rock beneath the stream has no particular structure and can be eroded equally easily in all directions. Tributaries join larger streams at acute angles (less than 90°).
What is dendritic drainage?
A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material. That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.
What is fluvial process?
fluvial process, the physical interaction of flowing water and the natural channels of rivers and streams. Such processes play an essential and conspicuous role in the denudation of land surfaces and the transport of rock detritus from higher to lower levels.
What is Insequent river?
Obsequent streams are streams flowing in the opposite direction of the consequent drainage. Insequent streams have an almost random drainage often forming dendritic patterns. These are typically tributaries and have developed by a headward erosion on a horizontally stratified belt or on homogeneous rocks.
What is non sequential?
Definition of nonsequential : not relating to, arranged in, or following a sequence : not sequential a nonsequential narrative style a nonsequential list of serial numbers.
What is the difference between Obsequent streams and subsequent streams?
Obsequent streams are streams flowing in the opposite direction of the consequent drainage. Insequent streams have an almost random drainage often forming dendritic patterns.
Why are the tributary streams called resequents?
The tributary streams flowing in the direction of the master consequents are called resequents. These are originated at much later date in comparison to the master consequents. Since they are of recent origin, and hence they are called resequent.
Why are the northward flowing streams called OB subsequent streams?
These northward flowing streams join the subsequent stream Sun Kosi which runs west to east, as obsequent streams because these are opposed to the directions of the master consequents like the Ganga and the Yamuna.
What are synclinal consequent streams?
Such consequent streams are called synclinal consequent streams, which become the master consequent streams of trellis drainage pattern at much later date. The first streams to be initiated on a newly emerged coastal plain are consequent streams which are parallel to each other and thus form parallel drainage pattern.
