Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core scientific disciplines?Hydrology, geomorphology, hydraulics, and environmental science
2. What is the key engineering structures?Dams, barrages, levees, floodwalls, canals, spillways, and revetments
3. Why do people build dams on rivers?Dams hold back water so we can use it for drinking, farming, or to spin turbines that make electricity. They also help stop big floods that could damage homes.
4. How do engineers decide where to put a dam or a canal?They study how water moves, how fast it flows, and how the river shapes the land. This helps them pick places that are safe and that won’t hurt the river’s natural shape too much.

Hydrology: The scientific study of the movement, distribution, and management of water on Earth.
Geomorphology: The scientific study of landforms and the processes that shape them.
Sediment Transport: The movement of solid particles (like sand and silt) by flowing water.
Ecological Flow: The quantity, timing, and quality of water flows required to sustain freshwater and estuarine ecosystems.
