🔍 Key Concepts

• River currents around a middle bar and how flow splits then rejoins downstream • Converging vs diverging currents and the surface patterns they create • Analogy to a boat’s bow wave vs wake and which way the V opens/points in each case

💭 Think About

• Picture water flowing around a bar: after it splits around both sides, what happens to the two streams when they meet again downstream? • When two currents converge, does the surface usually look rough with a visible line and V‑ripple, or extra smooth and glassy? • Compare the pattern behind a moving boat (wake V) with the pattern in front of an obstruction in current (bow V): which one is more like two currents meeting at the end of a bar?

✅ Before You Answer

• Be clear which way "downstream" is in your mental picture and which way the point of the V should face relative to the current • Decide whether converging flow (currents meeting) produces rough, disturbed water or a smooth, calm patch • Visualize whether the V shape at a meeting point is more like a wake behind something or a bow wave in front of something
