d) Not steep
Answer: b
Clarification: The erosion of the soil takes place where the longitudinal slope of the drainage is steep.

6. The longitudinal slope erosion can be corrected by __________
a) Compaction
b) Consolidated soil
c) Permeability
d) Void ratio
Answer: a
Clarification: The longitudinal slope of the erosion of soil may be corrected by using the compacted soil.
