1 Chapter 14: Streams and Floods Visit the Online Learning Centre at www.mcgrawhill.ca/college/plummerwww.mcgrawhill.ca/college/plummer Chapter 14: Streams and Floods What is the Hydrologic Cycle? What is a Stream? How do Drainage Patterns Reflect Geological Conditions? What Factors Affect Stream Erosion and Deposition? How Does a Stream Erode? How do Streams Transport Sediment? Where do Streams Deposit Sediment? Can We Predict When Floods Will Occur? How Do Stream Valleys Change With Time?
