Average discharge
Dominant discharge
Maximum discharge
Critical discharge
Answer is Right!
Answer is Wrong!
The correct answer is: A. Average discharge
The average discharge of a river is the amount of water that flows through a cross-section of the river per unit time. It is calculated by dividing the total volume of water that flows through the cross-section in a given period of time by the length of the period.
The average discharge of a river is important because it determines the amount of energy that the river has to erode its banks and bed. The higher the average discharge, the more energy the river has and the more likely it is to meander.
The other options are incorrect because they do not affect the meander pattern of a river.
- Dominant discharge is the highest discharge that occurs in a river over a given period of time. It is not as important as average discharge because it only occurs for a short period of time and does not have as much of an effect on the river’s meander pattern.
- Maximum discharge is the highest discharge that has ever occurred in a river. It is even less important than dominant discharge because it only occurs very rarely and does not have a significant effect on the river’s meander pattern.
- Critical discharge is the discharge at which a river begins to erode its banks. It is not as important as average discharge because it only occurs at a specific point in time and does not have a significant effect on the river’s meander pattern.
