Solutions for Canal Transition amid Low Water Levels

Reduced water levels along navigable inland waterways disrupt waterway transportation economics, but technology exists to maintain viable transportation. However, installing this technology often faces political controversy. Authorities responsible for waterways may need to consider drastic measures for economic reasons. Reduced water levels have impacted various waterways, including the St. Lawrence Seaway, the Panama Canal, the European canal system, the Mississippi River, and the McKenzie River. Past low water levels have forced vessels to carry reduced payloads or cease navigation in shallow areas.

Infrastructure modifications, such as adapting hydraulic pumping technology from the power industry, could increase navigable water depths. For example, pumping seawater inland to higher elevations could be achieved with wind power and ocean water energy conversion. A nuclear generation ship could also generate power to operate water pumps. The environmental impact of such modifications would need to be evaluated, along with the economic benefits of sustaining water depths for ship transportation.

Navigation lock water pumps could sustain water depths along navigation canals, particularly in areas without water-saving side tanks. Pumping seawater into channels might be necessary to maintain water levels at lower elevations. The installation of high-volume water pumps at navigation locks along the Panama Canal could be economically viable despite potential environmental impacts. Additional navigation locks and water pumps at strategic locations could sustain water levels during extended drought periods, benefiting national economies and international trade.
