Question

24. What are some strategies used to protect a coasti A. No answer choice is correct B. Seawalls D. Tombolos 25. I if the slope angle is greater than the angle of repose the slope is A Wavy B. Stable C. Fractured D. Unstable 26. What is the correct unit of the stream property known as "discharge"? A. km/sec B. km2/sec C. ft/sec3 D. ft3/sec 27. On Fig 2, point a is A. A latitude line B. A Quadrangle C. A longitude line D. The prime meridian 28. Refer to fig. 5 The slope angle of A lies in the range A. 20-30 degrees B. 10-20 degrees C. 50-65 degrees D. 90 degrees and above 29. In a meandering stream, the water travels faster along the outside bends: A. False B. True

Explanation / Answer

24. Sea walls. A wall built on the edge of the coastline. It prevent coastal flooding in some areas.

25. Unstable. The angle of repose is the highest angle at which the slope remains stable thus if the slope angle is greater than angle of repose then it becomes unstable.

26. ft3/sec. Discharge is defined as volume of liquid drawn per unit time.

27. insufficient data. Fig 2 is not given
28. insufficient data fig 5 is not given

29. True.  In real meandering rivers, we observe higher downstream fluid velocities at the outside bends. This is because the secondary flow effect dominates over that of irrotational flow.
