what is the apparent relationship between stream gradient and the shape of a stream valley?

High gradient streams tend to have steep, narrow V-shaped valleys, and are referred to as young streams. Low gradient streams have wider and less rugged valleys, with a tendency for the stream to meander.

Round has less surface area against the water so less "friction". It makes a big difference over long runs. Hi all, I was just told that round downpipes create better flow than rectangle ones.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... The steepness, incline, or grade of a line is measured by the absolute value of the slope. A slope with a greater absolute value indicates a steeper line.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... The direction of a line is either increasing, decreasing, horizontal or vertical.

When you stand next to a river, its path doesn't seem to move. ... All rivers naturally change their path over time, but this one forms meanders (the technical name for these curves) at an especially fast rate, due to the speed of the water, the amount of sediment in it, and the surrounding landscape.

V-shaped valley As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides. The rocks which have fallen into the river help the process of corrasion and this leads to further erosion.

River Valleys are densely populated than the plateaus because of the following reasons. ... 2) The climate at the places like river valleys is suitable for agricultural activities as these areas have fertile soil. 3) People live in these areas because fresh water is easily available here.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Answer and Explanation: When contour lines are closer to each other, the slope is steep. When contour lines are further apart from each other, the slope is gentle.

From this we can see that Canyons are geographical formations made by the erosion caused by running water over a long period of time while the Trenches are formed by the movement and collision of tectonic plates.

The difference: (i) The drainage pattern resembling the branches of a tree is known as “dendritic” the examples of which are the rivers of northern plain. (ii)When the primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as 'trellis'.

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

Examples: – a direct relationship – As the stream velocity increases, the stream can carry bigger sediment. 8. 9. – The physically weathered sediments are larger in particle size than the chemically weathered particles.

The difference lies in the lack of stability, in the presence of moving water, of loose sand or gravel banks, in the case of a braided stream. ... In general, braided reaches are steeper than meandering portions of the same stream.

If you keep the velocity in the channel below critical flow and velocity is below allowable for the ground cover then you have a gentle slope. If flows are critical flows or above and the velocity of flow is greater than the allowable for the ground cover then you have a steep slope.

Gradient is a measure of how steep a slope or a line is. Gradients can be calculated by dividing the vertical height by the horizontal distance.
