This activity provides you with an authentic problem that faces many scientists, politicians and citizens everyday. Rainfall, and the runoff and flooding that it produces, results in millions of dollars of damage to property, farmlands, houses, and businesses each year. In extreme cases, surface water runoff can result in injuries or death to humans and other living creatures.
This lesson will help you understand why water runs off during a storm. You will learn how factors like plants and buildings affect the amount of water that runs off a piece of land. You will use a computer model to evaluate the effect of converting a farm or forest to residential or commercial use.
Rain gardens are required in some communities to address the problem of additional runoff from developed land. In this lesson you will learn how to construct and calculate the size of water gardens needed. You will investigate the positive and negative effect of water gardens on a community.
