Rainwater Harvesting Math: the Runoff Coefficient

The video tutorial explains how to assess rainfall and calculate runoff on different surfaces. It covers the steps to estimate water infiltration and runoff for paved and earthen surfaces, highlighting the importance of understanding surface characteristics like soil compaction and slope. The tutorial also discusses the impact of organic matter on reducing runoff and enhancing water infiltration.

What is the significance of calculating the amount of water infiltrating a surface?

What is the estimated percentage of rainfall that typically runs off a paved surface?

How does the infiltration of water differ between paved surfaces and earthen surfaces?

What factors influence the runoff coefficient when estimating water runoff?

Explain how organic matter affects the runoff coefficient of a pathway.
