In the process of stream erosion and valley evolution, streams have a universal
tendency to erode headward, or upslope, and to increase the lengths of their
valleys until they reach the divide. Headward erosion can be analyzed by
referring to ...

Physical Geology: Exploring the Earth
Headward erosion takes place at the upper end of a stream thereby lengthening
it. In some cases, headward erosion breaches a divide and diverts some or all of
the drainage of another stream system by stream piracy. Downcutting takes ...

Vertical, lateral and headward erosion River erosion may result in: • vertical
corrasion • lateral corrasion • headward erosion. Vertical corrasion This is a
characteristic of fast-flowing rivers that are transporting a large bedload of coarse,
hard ...

Encyclopedia of Geomorphology
In some cases a waterfall cascades over the lip into the main valley, but in high
mountain areas headward erosion of the tributary stream has usually cut a
narrow gorge into the lower reaches of the hanging valley floor. Outside
previously ...

Streams on the right drain to the Usk and the sea at Newport; their headward
erosion threatens to capture the stream and lake on the left, draining to the Taff
and the sea at Cardiff. (Aerofilms Ltd) "Te EFFECTS OF FOLDING AND
FAULTING ...

At the other is the 'expansion' mode in which lateral and headward growth occur
together to give a more or less complete network which slowly extends headward
. In between is the 'extension' mode, which is closest to that proposed by Glock ...

The Origin of Mountains
likely to be steeper, and so more erosive, and headward erosion will cause
headward erosion or rivers, and when valleys coalesce there will be inland
retreat of the Great Escarpment. In the Lake Albert style of rifting, landscape
evolution is ...
Cliff Ollier, C. F. Pain, 2000
The farther a spring head retreats, the greater the flow convergence that it
generates, thereby increasing the rate of headward erosion. Headward sapping
proceeds faster than valley widening because the valley head is the site of
greatest flow ...

Rivers and Floodplains: Forms, Processes, and Sedimentary Record
Experimental and field studies of the initiation and evolution of channel systems
on freshly exposed, regular surfaces composed of homogeneous material
demonstrate that channel systems evolve by headward extension (elongation) of

Tectonics, Climate, and Landscape Evolution
Note that these calculations assume no major increase in the size of the
headwaters, which might be expected because of headward erosion. However,
catchments rather compete with the systems that discharge to the east (i.e.,
Altiplano; ...
