Over time, these waterways can become filled with sediment that makes them difficult to navigate and sometimes pose an environmental hazard. We depend on various waterways for several daily functions, ranging from transporting goods to commercial fishing and recreation.
In coastal areas, sediment accumulation can cause beaches to erode.
It can also lead to contamination that poses a threat to aquatic plant and wildlife. For instance, it can reduce the depth of the waterway and prevent the passage of ships. Sedimentation is a naturally occurring process where silt, sand and other debris accumulate on the bottom of rivers, lakes, canals or streams over time. An excessive build-up of sediment can cause a series of issues. Dredges are specialized pieces of equipment that create a vacuum to suck up and pump out the unwanted sediment and debris. Professor Emily Shuckburgh, a climate scientist at the University of Cambridge, said firms such as Shell should focus on accelerating the green transition “rather than trying to suggest the most vulnerable in society are in any way best served by prolonging our use of oil and gas”.Table Of Contents – Easily Jump To What You’re Looking For:ĭredging means the process of removing accumulated sediment from the bottom or banks of bodies of water, including rivers, lakes or streams. Shell’s annual shareholder meeting in May was disrupted by protesters chanting “go to hell” and attempting to storm the stage, with the chaotic four-hour event dominated by accusation that the company was putting the climate at risk.

The Shell chief executive warned that increased demand from China and a cold winter in Europe could push prices higher, impacting bills. Wael Sawan insisted that the world still “desperately needs oil and gas” to avoid a surge in energy costs as households struggle with the cost of living. Cutting oil and gas production risks increasing poverty by driving up the cost of living, the boss of Shell has warned.
