River valleys
![Palakaria-and-Belchin-3](https://upload.wikimedia.org/wikipedia/commons/5/50/Palakaria-and-Belchin-3.jpg)
The development of a river valley is affected by the character of the bedrock over which the river or stream flows, the elevational difference between its top and bottom, and indeed the climate. Typically the flow will increase downstream and the gradient will decrease. In the upper valley, the stream will most effectively erode its bed through

In the middle valley, as numerous streams have coalesced, the valley is typically wider, the flow slower and both erosion and deposition may take place. More lateral erosion takes place in the middle section of a river's course, as strong currents on the outside of its curve erode the bank. Conversely, deposition may take place on the inside of curves where the current is much slacker, the process leading to the river assuming a

Glacial valleys
![Glacial Valley MtHoodWilderness](https://upload.wikimedia.org/wikipedia/commons/4/4a/Glacial_Valley_MtHoodWilderness.jpg)
There are various forms of valleys associated with glaciation. True glacial valleys are those that have been cut by a glacier which may or may not still occupy the valley at the present day. Such valleys may also be known as glacial troughs. They typically have a
U-shaped cross-section and are characteristic landforms of mountain areas where glaciation has occurred or continues to take place.
The uppermost part of a glacial valley frequently consists of one or more 'armchair-shaped' hollows, or '
cirques

Fjærlandsfjord is about 400 meters deep while the main fjord nearby is 1200 meters deep. The mouth of
Ikjefjord is only 50 meters deep while the main fjord is around 1300 meters at the same point.
Glaciated terrain is not the only site of hanging streams and valleys. Hanging valleys are also simply the product of varying rates of erosion of the main valley and the tributary valleys. The varying rates of erosion are associated with the composition of the adjacent rocks in the different valley locations. The tributary valleys are eroded and deepened by glaciers or erosion at a slower rate than that of the main valley floor; thus the difference in the two valleys' depth increases over time. The tributary valley, composed of more resistant rock, then hangs over the main valley.
