Underwater excavation is called dredging. While essential to maintain ports and channels and to meet other needs, such as fighting the impacts of climate change by building sand dunes, such operations can cause severe environmental impacts in the marine environment. This chapter overviews the dredging process and equipment, followed by a presentation of the environmental concerns associated with dredging and disposal or placement for beneficial uses. The chapter concludes with a brief discussion of the international regulatory regime and remarks on future trends - hydraulic dredging.

A typical dredging project goes through several phases, and data is collected during each: Project planning, advertising, bidding, contract award, contractor, dredge equipment, dredging, placement, inspection, timekeeping, project completion, and payment. We provide access to dredging resources that can be used to record data, monitor dredging activities, and answer critical dredging-related questions - Harbor Pile Driving.

Yet only a few of them are naturally deep. In most of them, channels must first be excavated to a Congressionally mandated depth and then dredged periodically, so they will remain clear and safe for navigation. Without dredging, many waterways, ports, and harbors would become impassable to commercial and recreational vessels. Regular maintenance dredging is of enormous importance in coastal regions with sizeable tidal activity and in water our bodies are vulnerable to becoming silted with sediments, sand, and dust.  This is a form of dredged material disposal that entails managed placement of dredged materials right into a subaqueous site with some type of lateral confinement. The lateral confinement may be provided by a backside melancholy or by subaqueous berms. For more information please visit our site https://www.Pacificmaritimegroup.com/
