This thorough resource examines how untreated runoff impacts wetlands, efforts by the EPA to educate landowners on how to protect wetlands, the use of wetlands to treat runoff, and current EPA programs that address runoff.

EPA site offers answers to what nonpoint source pollution is as well as provides links and information as to what concerned citizens can do about it.

After creating a model, students will investigate factors that affect water runoff both positively and negatively, and the impact this has on the quality of groundwater.

Rainforests at the Crossroads: Examine the relationship between rainfall and runoff on Barro Colorado Island (BCI) over a period of one year. Then examine the data and use the TI-73 Explorer to graph and analyze the values.

A demonstration that shows students how water systems are connected and the concept of non-point source pollution. Also it allows students to see how pollution on their playground could affect larger water supplies.

This lesson teaches the concept of a watershed and why it is important in the context of engineering hydrology. Learners learn about runoff and how we visualize runoff in the form of hydrographs.

Learn about the different stages of the Earth's water cycle, and about processes involving water, including runoff, infiltration, and the differences between hard and soft water.

A lab experiment, in a series of experiments, that investigates fisheries. In this lab, students test the effects of fertilizers and other pollutants on a model ecosystem. Students also examine 2 years of ocean color (chlorophyll...

In this environmental science fair project, students will build models of fields prepared by plow-based and no-till methods, and see which ones are best at retaining soil moisture and preventing surface runoff.

For young scholars that have already been introduced to the water cycle, this lesson plan is intended as a logical follow-up. Students will learn about human impacts on the water cycle that create a pathway for pollutants beginning with...

This website focuses on water quality issues in relation to urbanization. There are helpful links to brief articles on topics like storm runoff, wastewater, and the underground water table. Click "Water Science School HOME" to access the...

When it rains, some of the rainwater soaks into the ground, and part of it flows over the ground and directly into creeks, streams, or rivers. This water that runs off into the river is called runoff, or sometimes stormwater runoff....

Rainforests at the Crossroads: Collect runoff from two simulated sites: 1) a tray with soil, 2) a tray with soil and vegetation, to see how vegetation affects erosion and to compare and examine the runoff from the sites.

This lesson helps young scholars discover the relationship between precipitation, evaporation, and surface runoff data. Using FieldScope, an online GIS created at the National Geographic Society, students will explore data layers, create...

The most common problem on the Catawba River and its lakes is sedimentation. Sediment carried by stormwater runoff from construction sites in North Carolina has been documented as the leading source of non-point source pollution to...

[Free Registration/Login may be required to access all resource tools.] Discusses how flowing water causes erosion; describes how runoff, streams, and rivers change Earth's surface; and identifies features caused by groundwater erosion.

Students identify the watershed they live in and study the pathway of surface runoff which ultimately becomes the source of water used at home,

Find out how water pollution can be prevented and how it affects you.

A simple experiment that demonstrates how water is absorbed into soil and filtered through it, showing how water changes things in the environment. After a class demonstration, they will themselves investigate the effects of water...

A collection of video lectures from a course on water resources engineering. Webpage includes twenty-eight lectures from a professor at the National Programme on Technology Enhanced Learning. Lectures vary in length and cover topics like...

Solve the crossword puzzle and learn more about stormwater and runoff pollution.

Students explore the chemistry behind the causes and effects of acid mine drainage on a modeled river. In this activity, students examine the chemistry of acidic mine runoff and its effects on river water.

Information about the first federal legislation to address pollution caused by stormwater runoff from the landscape.

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...
