Waterway navigation encompasses port development, port maintenance, waterway creation, and waterway maintenance. This not only applies to rivers or sea ports, but also to lakes, streams, and marinas. While smaller lakes and streams are generally referenced as recreational dredging, they still play a major role in dredging, and have an effect on local economies. Typically, the general population sees a dredge as an underwater vacuum cleaner and most commonly associates them with port or waterway maintenance.
Ironically, the main reason the global economy has grown is due to the development of port systems around the world. In fact, no other single factor has prompted continual growth of the world’s nations; both in their economies and in their nations’ overall well-being. Without port systems, the only form of trade would be the barter system. Without proper funding, port systems would decline, along with the region’s overall economy.
