Keyline® in the AR Sandbox #3: Design for Water

The video tutorial covers the design layers for water management in a watershed, focusing on the water catchment, retention, irrigation, and reconstitution zones. It explains the importance of key points and key lines in managing water flow and storage, and highlights the role of these systems in drought-proofing farms. The tutorial also discusses the legal considerations involved in water manipulation and the importance of adhering to regulations.

What is the primary function of the water catchment zone?

• To create wetlands

• To divert water to ridges

• To allow water to soak into the soil

• To store water in ponds

What is the significance of the key point in the water retention zone?

• It is where the slope changes from steep to gentle

• It marks the start of the irrigation zone

• It is the highest point in the landscape

• It is the lowest point in the valley

Which of the following is a key feature of the water retention zone?

• It is the final destination for water flow

• It is primarily used for irrigation

• It includes the key point and key line

• It is located at the lowest point in the landscape

How does water move between key point ponds?

• By overflowing and wrapping around ridges

• Through natural evaporation

• By being pumped manually

• Through underground channels

What is a potential benefit of storing water on ridges?

• It reduces the risk of flash floods

• It increases soil erosion

• It decreases water availability

• It prevents water from reaching valleys

What is the purpose of key line pattern cultivation?

• To prevent water from soaking into the soil

• To gently drift water from valleys to ridges

• To direct water from ridges to valleys

• To create ponds in the valleys

What is the role of the irrigation zone in the landscape?

• To store excess water

• To prevent water from reaching the valleys

• To create new water catchment areas

• To distribute water using gravity

How do key line patterns affect water distribution during heavy rains?

• They help water drift towards drier ridges

• They prevent water from soaking into the soil

• They increase water flow to valleys

• They direct water to the lowest point

What is the main goal of the water reconstitution zone?

• To irrigate crops using gravity

• To create artificial lakes

• To store water in high elevation ponds

• To restore wetlands and wildlife habitats

Why is it important to consider legal regulations in water management?

• To increase water flow to ridges

• To avoid legal penalties and protect ecosystems

• To ensure water is stored at the highest point

• To maximize the number of ponds
