How Water Moves

Interactive learning modules cover basic information about how water and pollutants move through and beneath Nebraska’s watersheds.

Modules may be completed in any order, but are listed in order from more basic to more complex. To start a module, just click on the title image.

After completing each module, please consider sharing your feedback through the survey links.

What is a watershed, and how does watershed delineation help us manage water resources? Learn key watershed characteristics. Identify key stakeholders to involve in watershed management planning. (Send us feedback.)

Groundwater Quantity Educational Module 1

Learn the basic water balance components for a groundwater system. Use water data and groundwater maps to determine whether a groundwater system is in balance. (Send us feedback.)

Groundwater Surface Water Interactions Educational Module 2

How do streams and groundwater interact? Learn how groundwater and surface water levels affect water movement, and understand how pumping can impact streamflow. (Send us feedback.)

Link to interactive learning on groundwater nitrate

Have you ever wondered why groundwater nitrate concentrations vary in aquifers? One reason is that there are substantial lag times between groundwater quality changes and the human activities that cause them. These lags can cause distinct patterns of groundwater age and quality in aquifers. This module introduces the concept of groundwater age and how age information can be used to understand groundwater variables, including nitrate and recharge.
