which statement best evaluates the impact of dredging on the physical environment?

The impact of dredging on the physical environment can vary. It can have both positive and negative effects depending on various factors, such as the location, scale, and purpose of dredging.

Dredging can be beneficial as it helps maintain waterways, rivers, and harbors by removing sediments, improving navigation, and preventing flooding. It can also help restore ecosystems by removing pollutants and improving water quality.

However, dredging can also have negative impacts. It can disrupt natural habitats and ecosystems, leading to the loss of biodiversity. Dredging can also stir up sediments, causing increased turbidity and potentially harming aquatic organisms. The disposal of dredged materials can also be a concern if proper management practices are not followed.

Therefore, the impact of dredging on the physical environment can only be best evaluated by considering the specific circumstances and implementing appropriate mitigation measures.
