Question 1 of 27070

🔍 Key Concepts

• Mississippi River chart symbols for river training structures • Difference between bank protection and current-directing structures • How fixed structures that extend from the bank are drawn on river navigation maps

💭 Think About

• Ask yourself: which of these options is normally built projecting out from the bank into the channel to control current or sediment? • Which feature on a river chart would be shown as multiple short, repeated lines extending from the shore rather than one continuous line along the bank? • Consider which items are used mainly for mooring/towing operations versus which are civil works structures shown for navigation and channel control.

✅ Before You Answer

• Identify which answer choices are structures vs. areas (for example, can you ‘tie up’ to it or is it just a place on the river?) • Decide which feature would logically need to be plotted where it sticks into the river and could affect traffic or water flow. • Recall that some structures are primarily bank protection along the shoreline, while others jut out perpendicular or at an angle from the shore. Match that to the chart symbol of black lines extending from the bank.
