Infront of the sea wall the gradient dips down because the waves are pushed up against the wall and there is a strong backwash so that's why it dips down. This is beach scouring.
Concentration Gradient
The higher the frequency the steeper the shoreline will be. It will be steep at high tide shoreline and level out between that and the low tide shoreline. I think.
find the gradient
The answer depends on the gradient of WHAT!
what do you mean by gradient of a scalar field? what do you mean by gradient of a scalar field?
basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.
Danube river gradient
these tiles are gradient.
(-1.5,0) (1.5,0) what is the gradient?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
Gradient= Vertical gain / Horizontal distance Hope this helps ;P
