In afflux, the rise in water level is due toa)obstruction by the dam ...
Afflux: Afflux is an increase in water level that can occur upstream of a structure, such as a dam, bridge, or culvert, obstructing the flow.

On the upstream side of the dam, the depth of the water will be rising due to obstruction/barrier. If there had not been any obstruction (such as a dam) in the path of the flow of water in the channel, the depth of water would have been constant parallel to the bed of the channel. Due to obstruction, the water level rises, and it has maximum depth from the bed in some sections.
This rise of water level on the upstream end is termed as afflux.

Explanation:
Afflux is a term used to describe the rise in water level that occurs due to an obstruction in the flow of water. This obstruction can be caused by various structures, including dams, bridges, and waterways. However, the correct option for this question is "A," which states that the rise in water level is due to obstruction by the dam in the flow of water. Here's why:
- Dams are built across rivers to regulate the flow of water and generate hydroelectric power. When water flows towards a dam, it gets obstructed by the dam's structure, which causes the water level to rise upstream.
- The rise in water level due to a dam is called "damming effect" or "backwater effect." This effect occurs because the dam creates a barrier that prevents the water from flowing freely downstream.
- The height of the water level rise depends on the height and width of the dam, as well as the volume and velocity of the water flowing towards it.
- The rise in water level due to a dam can have significant impacts on the environment and human activities. For example, it can flood nearby areas, affect water quality, and alter the habitat of aquatic species.
In summary, afflux is caused by an obstruction in the flow of water, and dams are one of the structures that can cause it. Therefore, option "A" is the correct answer for this question.
