Little change in elevation, or a low gradient
This indicates steeply ascending or descending terrain. The distance between the lines indicates different elevations, so lines that are closer together indicate steep places while lines that are farther apart indicate smoother terrain.
A. The way that contour lines bend when they cross a stream is always upstream. B. Circles that are closed contours signify hills. C. Closed contours with short lines pointing downward are closed depressions and have no outlet. D. Gentle slopes are characterized by lines farther apart, while steep slopes are characterized by lines closer to one another. E. Maximum relief is the different elevations between highest and lowest points in an area.

Contours for a gentle slope are spaced equally and far apart, the closer the contour lines the steeper the slope.
Contour lines that are close together on a topographic map indicate an area of steep slope. If they essentially overlap you have a cliff.
Contours show the elevation above sea level. The steeper the slope the closer the contour lines. Therefore, on a low elevation the contours will be far apart.

Flat (gently sloped)
The contours of the water table lines are the same as the contours of other topographical lines. The only indication of water tables might be elevation lines but they are not unique to water tables.
