Keyline® in the AR Sandbox #1: Contour Lines and Water Flow

The video tutorial explains the significance of understanding water lines, contours, divides, and drainages in landscapes. It highlights the work of PA Yeomans and the Key Line design system, emphasizing how land shape affects water movement, soil distribution, and ecosystem layering. The tutorial covers contour lines, ridges as water divide lines, and drainage patterns, illustrating how these elements influence water flow and landscape design. It also addresses exceptions in typical patterns, such as those found in glacial or coastal regions.

What are the three major water lines within the landscape that need to be recognized?

Why is it important to understand the shape of the landscape?

How do contour lines represent elevation in the landscape?

What is the significance of ridges in relation to water flow?

Explain the concept of watersheds and their importance in landscape analysis.

Describe how contour lines change in relation to steep and gentle slopes.

How can contour maps help in identifying higher and lower features in the landscape?

How do drainage patterns resemble a tree structure?

What happens to water flow when the landscape becomes saturated?

What are some exceptions to the typical watershed patterns mentioned?
