Dredging is an efficient, but a relatively costly technique to reduce an internal loading problem when the right equipment is used (cutterhead suction dredging is often efficient: Figure 2).It may also serve to deepen a lake that is gradually filling in. Due to the potential content of toxic substances in the sediment a key problem of dredging is how to …
