Valley floor width to valley height ratios (Vf) mean values along the studied fault range between 0.21 and 2.50.
Valley floor width to valley height ratios (Vf) mean values along the studied fault zones range between 0.5 and 1.6.
The resulting modified surfaces contained texture geometries with pre-definable peak-to-peak widths, valley-to-peak heights, and texture directions.
The diagnostic parameters selected for the classification are floodplain width, floodplain (or valley floor) slope, valley confinement (expressed by a longitudinal profile index, LPI), channel sinuosity (indicating river mechanism), and valley depth.
The Vf index is the ratio between the width of the valley floor and the mean height of the valley.
At Kamen-na-Obi, however, where the river begins to bend northeastward, the width of the valley shrinks to 2 to 3 miles (3 to 5 km).
Finally, the lower section of the Don has a valley width of 12 19 miles, with a huge floodplain and a braided river channel as much as 66 feet deep.
From the mouth of the Vitim to the Olyokma, the river skirts the Patom Plateau, on the right bank, forming an enormous bend; the width of the valley increases in places to 20 miles (32 km).
Downstream the banks rise, and the width of the valley to Orsha varies for the most part from two to six miles, narrowing to less than half a mile in places.
Data for rivers in the region shows a strong linear relationship between valley width and drainage area.
In such circumstances, can variation in valley width influence channel morphology, forcing riffle pool location and persistence?
