🔍 Key Concepts

• Inland river charts and symbols for the Western Rivers (AHP = Above Head of Passes on the Mississippi River) • The differences between dikes, revetments, weirs, and fleeting areas in terms of structure and purpose • How shaded areas along a bank are typically used on river charts to warn mariners

💭 Think About

• Ask yourself: Which of these features is usually built along the bank to protect it, rather than projecting out into the channel or being a designated mooring area? • Think about which feature is most likely to be hazardous if you get too close to the bank, and therefore would need to be shaded or specially marked on a river chart. • Consider how each option looks in real life: Would dikes, weirs, revetments, or fleeting areas be shown as a broad shaded band along the shoreline?

✅ Before You Answer

• Verify in a Western Rivers / Mississippi River chart legend how bank protection and underwater structures are depicted. • Check the definition and purpose of each: dike, revetment, weir, fleeting area. • Confirm which of these is normally parallel to the bank and which are perpendicular or separate areas in the river.
