Gradient

The slope,or change in elevation,of land or improvements such as a pipe or a road.It is expressed as the ratio of inches (or feet) of rise or fall over a specified distance. It is similar to the concept of pitch in roofing.Figure A (above) has a gradient of 1:12 because the grade increases by 1 foot over a distance of 12 feet. Figure B has a gradient of 1:6.

First, at the level of 5% of flow depth from bed, the longitudinal flow is so strong all along the bend that it always dominates the secondary flow, and keeps the maximum velocity near the inner wall in all directions at the end of bend where, as shown in Figure 8a, the maximum velocity is again oriented towards outer wall due to the longitudinal pressure gradient at the bend exit.
