[amp_mcq option1=”A horizontal benching provided on the inside slope” option2=”A horizontal benching provided on the outside slope” option3=”A vertical benching provided on the outer edge of the bank” option4=”A vertical benching provided on the inner edge of the bank” correct=”option1″]
The correct answer is: A counter berm is a horizontal benching provided on the inside slope.
A counter berm is a type of embankment that is used to control erosion. It is typically constructed on the inside slope of a bank, and it helps to prevent the bank from collapsing. Counter berms are often used in conjunction with other erosion control measures, such as riprap and gabions.
Here is a brief explanation of each option:
- Option A: A horizontal benching provided on the inside slope. This is the correct answer. A counter berm is a horizontal benching provided on the inside slope of a bank. It is typically constructed of stone, concrete, or earth, and it helps to prevent the bank from collapsing.
- Option B: A horizontal benching provided on the outside slope. This is not the correct answer. A counter berm is not typically constructed on the outside slope of a bank.
- Option C: A vertical benching provided on the outer edge of the bank. This is not the correct answer. A counter berm is not typically constructed as a vertical benching.
- Option D: A vertical benching provided on the inner edge of the bank. This is not the correct answer. A counter berm is not typically constructed as a vertical benching.
