Stream gradient - Wikipedia, the free encyclopedia
Stream gradient is the ratio of drop in a stream per unit distance, usually expressed as feet per mile or meters per kilometer. A high gradient indicates a steep slope and rapid flow of water (ie. mo...

The formula for gradient is: the difference in elevation between two points on the stream distance along the stream; or the; RISE; RUN; Using this formula, calculate the gradients in the problems below. 1. The stream drops 500 feet in 10 miles.

Another relationship to consider is that of gradient. Gradient is the slope of the stream and is measured by the difference in elevation between two points on a stream ... The gradient influences the velocity of the stream. The steeper the gradient, the higher will be the velocity if all other factors are held constant.

Patterns of body size and net construction suggest that current speed and food-particle concentration (not size) influence the distribution of suspension-feeding caddisflies on a downstream gradient. Large ancestral taxa with high filtration rates occur in resource-poor upstream habitats;

Finally, from the downstream hydraulic geometry equation the change in stream gradient can be expressed in terms of discharge or area as a power function. Because these relations are identical in form and in their independent parameters, rates of change in slope obtained by all three approaches should be equivalent.

Results are presented so that velocity and temperature profiles, momentum and displacement thicknesses, and wall shear stress can be calculated for flows over two-dimensional bodies with arbitrary free-stream velocity distributions.
