Dredge

Imagine you're cleaning out a cluttered garage filled with boxes, old tools, and miscellaneous items that have piled up over the years. This task is similar to the operation of dredging, where material is excavated from a water environment, such as removing sediment from a riverbed. Just as you sift through and remove unnecessary items from your garage to make it more functional, dredging involves removing accumulated debris and sediment from waterways to maintain or deepen navigable channels, ensuring they remain efficient and clear for use.
