The sediment transported by a stream or channel may be divided into
- ABed load
- BSuspended load
- CWash load
- DAll of theseCorrect
Solution
Concept
Modes of Sediment Transport
Formula
No specific mathematical formula is required, as this is a conceptual classification of sediment transport types.
Step-by-step solution
Identify the three primary modes of sediment transport in a stream (bed load, suspended load, and wash load) and select "All of these".
Explanation
Option d ("All of these") is correct because sediment moving in a stream is categorized into three main types based on how it travels: bed load (particles rolling or sliding along the bottom), suspended load (particles kept floating by water turbulence), and wash load (very fine particles continuously held in suspension).
Shortcut
Remember the acronym BSW: Bed load, Suspended load, and Wash load. Since all three are modes of sediment transport, the answer is "All of these".
Common mistake
Selecting only "Bed load" or "Suspended load" upon recognizing them individually, while failing to realize that wash load is also a component and that "All of these" is the complete answer.
Correct answer: D) All of these
