Dams Ryan Nagelhout

Human impact on the environment is often difficult to track, but not when it comes to dams. These massive engineering projects create huge changes in our waterways and how we use them. Full-color photographs illustrate how engineers create water reservoirs and create hydroelectric power using a variety of dams. Readers will also see how dams create recreational activities for humans while others directly impact animal habitats and require further human engineering to safely bypass these water barriers.
