Dams change the landscape, providing reservoirs of freshwater and even producing electricity. Discover the engineering behind dams.

This is the engrossing story of the unsung heroes who did the day-to-day work of building Arizona's dams, focusing on the lives of laborers and their families who created temporary construction communities during the building of seven major dams in central Arizona. The book focuses primarily on the 1903-1911 Roosevelt Dam camps and the 1926-1927 Camp Pleasant at Waddell Dam, although other camps dating from the 1890s through the 1940s are discussed as well. The book is liberally illustrated with historic photographs of the camps and the people who occupied them while building the dams.

Explores the engineering challenges behind building dams, as well as the creative solutions found to overcome those challenges. Accessible text, vibrant photos, and an engineering activity for readers provide a well-rounded introduction to the engineering process.

Offers compelling insight into how designer Eastwood battled government bureaucrats, corporate patrons, and fellow hydraulic engineers to build seventeen dams in the western U.S. during the early twentieth century based on his innovative multiple-arch design. Reprint.

Canals and Dams: Investigate Feats of Engineering invites children ages 9 and up to explore the innovation and physical science behind the amazing waterways and barriers our world depends on. Trivia and fun facts illustrate engineering ingenuity and achievements from ancient aqueducts to the Suez Canal and the Hoover Dam. Readers will discover that engineers and builders alike put their lives on the line to advance civilization, experiencing triumphs and tragedies in building big. Through dazzling success and heartbreaking failure, they developed increasingly sophisticated tools and building methods. Activities and projects encourage children to explore the engineering process and to try, try again through trial and error. They'll engage in hands-on explorations of buoyancy, Newton’s third law of motion, and forces that push and pull structures. They’ll create a paper-cup zip line, build an arch, and simulate a tsunami, while experimenting with gravity, hydroponics, and velocity. In Canals and Dams: Investigate Feats of Engineering, children will gain an appreciation for the important field of engineering as they develop their own building skills.
