1. Keyline patterns DO NOT SEND WATER UP HILL/SLOPE.
2. There is a gradient of fall towards the centreline of primary ridges away from the centreline of the adjacent primary valley.
3. This gradient is formed by the use of cultivators that follow the keyline patterns described. Think of a cultivated line like a channel. If the channel is level water stays level, just like in a bath. If the channel has a gradient then the water, with gravity, will fall in the direction of that gradient.

It can be very subtle in humid landscapes or very abrupt in more brittle landscapes typically. The keyline is the contour of the keypoint within this primary valley and does not extend onto the primary ridge form. This is absolutely critical to your understanding of keyline patterning. The keyline of saddles is similar and doesn't extend to the adjacent main ridge crest forms.
5. No two contours are parallel. Again this is critical to understand and this is one of the key reasons why keyline patterns work in the way they do, and universally as the orders of patterns of topography are universal.
