Dredging - GCSE Geography Definition

Dredging is the process of removing sediments and debris from the bottom of lakes, rivers, harbours, and other water bodies. This activity is essential for maintaining waterways, ensuring they are navigable and free from obstruction. It plays a crucial role in supporting economic activities, such as shipping and fishing, by preventing harbours and ports from becoming silted up. In GCSE Geography, students might explore dredging in the context of river management, coastal defences, and human impacts on water systems. Dredging can have both positive effects, such as preventing flooding, and negative impacts, like disrupting aquatic ecosystems.
