headward erosion

Headward erosion is rapid at this point and regrading of the river starts to work back from the mouth.

However, the flood was not long or large enough to complete headward erosion through the entire sequence of pyroclastic material.

Possible explanations include headward erosion or a broken natural dam of a lake or river.

This leads to increased erosion at the steepest parts, which is headward erosion.

Geologically, the Schurwald is a dissected cuesta, formed by headward erosion.

Insequent streams form by random headward erosion, usually from sheetflow of water over the landform surface.

Subsequent streams are streams whose course has been determined by selective headward erosion along weak strata.

Subsequent streams form by selective headward erosion by cutting away at less resistive rocks in the terrain.

These are typically tributaries and have developed by a headward erosion on a horizontally stratified belt or on homogeneous rocks.

From 5.5 million to 5 million years ago, headward erosion to the north and east consolidated these streams into one major river and associated tributary channels.

Instead headward erosion has excavated large amphitheater-shaped features in the Cenozoic-aged rocks of the Paunsagunt Plateau.

Headward erosion and mass wasting helped to erode cliffs back into their fault-bounded plateaus, widening the basins in-between.

Dhansari river along with Kapili by headward erosion has completely isolated the Mikir hills from the Peninsular plateau.

If headward erosion continues long enough, it can cause a stream to break through into a neighboring watershed and capture drainage that previously flowed to another stream.

Headward erosion creates three major kinds of drainage patterns: dendritic patterns, trellis patterns and rectangular and angular patterns.

Headward erosion of one of those tributaries, the Paria River, eroded north-northwestward toward what is now Paria Amphitheater.

Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin.

Mushaway Peak is in fact an erosional remnant of what was once a must larger Llano Estacado that has gradually retreated by the process of headward erosion.

Alternatively, a water gap can be formed through headward erosion of two streams on opposite sides of a ridge, ultimately resulting in the capture of one stream by the other.

Through a process called headward erosion, it gradually moved eastward, gobbling up the land around its headwaters in Pac-Man fashion, until it met up with the ancestral upper Colorado.

(Santa Cruz, 2006) It has been observed at least since 1990 that a ravine of Arana Gulch appeared to indicate headward erosion due to concentration of surface runoff.

Individual lava domes have volumes up to 9.4 x 10m and headward erosion has further modified the volcano by incising youthful V-shaped stream canyons into the lava plateau margin.

Three kinds of streams are formed by headward erosion: insequent streams, subsequent streams, and obsequent and resequent streams (See Fluvial landforms of streams.)

As each capture added to the Shenandoah's discharge, it accelerated the process of headward erosion until the Shenandoah captured all drainage to the Potomac west of the Blue Ridge Mountains.

Most of the terraces are preserved as flattenings on spurs and it is possible that similar features might result from wasting of a spur due to attack by the headward erosion of valleys on either side.
