What is sedimentation in the context of construction activities?

1. Settling of solid materials in water

2. Accumulation of soil particles in the air

3. Movement of water carrying sediment particles

4. Formation of durable ground surfaces

The correct answer is: Settling of solid materials in water

Sedimentation in the context of construction activities refers to the process where solid materials settle out of water. During construction, activities such as excavation and grading can disturb the soil, leading to soil particles being washed into nearby water bodies by rain and runoff. As the water slows down, the heavier particles settle to the bottom, creating sediment. This process can impact water quality and aquatic habitats, making it essential for construction projects to implement sediment control measures to minimize runoff and manage sedimentation effectively. Understanding sedimentation is critical for ensuring compliance with environmental regulations and protecting natural resources during construction activities.
