Jennifer Jett, NBC News, 19 July 2023 Global warming is only heating things up Although a high-pressure system is currently causing this relentless heat wave across parts of the Southwest, Kunkel also believes global warming is adding more ingredients to the mix. are experiencing a relentless heat wave, with more records expected to be broken this week. Naveen Kumar, Variety, 20 July 2023 Meanwhile, millions of people across the U.S. Michael Williams, Dallas News, 20 July 2023 America, too, has since fallen under the shadow of a strongman of relentless ego. Dennis Pillion | al, 20 July 2023 For months, McGillis told The News during a three-hour conversation, she and other members have been subjected to relentless harassment because of Lindsay-Reinhardt’s Facebook posts and their newfound attention. Dan Frosch, WSJ, 21 July 2023 Local residents complained of health problems from smoke inhalation, as well as damage to their homes and other belongings from the relentless smoke. Detroit Free Press, 22 July 2023 Photo: Callaghan O’Hare/Reuters The relentless heat wave that has smothered parts of the country in triple-digit temperatures is drawing calls from workers’ advocacy groups and others for greater protections for those who work outside-from construction workers to farmworkers to garbage collectors. A cost/benefit analysis is advised: evaluating the benefits to be gained or the impacts associated with the excavation process and materials excavated.Recent Examples on the Web Deer flies especially are relentless pests known to strike at any unknowing passerby which crosses their path. The transportation and placement phases require equal consideration and emphasis in the planning stages. The next steps are transport of these materials and finally the placement or disposal of the materials depending on the type of material and whether it is clean or contaminated. Transporting and placing dredged materialĮxcavation is, however, only the first phase of the dredging process. Since visibility is limited, sophisticated technologies have been developed to visualise and guide the work. Underwater technologiesĭredging excavation occurs underwater, often in deep water, where the process cannot be seen. To define the quantity or area to be dredged, acoustic sounding techniques are often used.Įnvironmental impact assessments are also a crucial part of project planning for dredging. These help the client and contractor to understand the nature of the materials to be dredged. Most projects require extensive pre-dredging preparation including a variety of bathymetric, geological and geophysical analyses. Planning, design, constructionĭredging requires thorough planning, design and construction, which involve engineers, scientists and highly trained crews representing a wide range of skills. Modern dredging vessels and technologies can collect and transport large quantities of sand to improve and expand existing ports, and to build land reclamations, which form platforms for offshore airports, residential and commercial areas. Maritime Infrastructureĭredging is used to address a broad range of maritime infrastructure needs – with economic, social and environmental implications.ĭredging deepens ports and access channels to accommodate global waterborne freight transport of goods.ĭredging also excavates or ‘mines’ sand from far offshore and then transports these materials to onshore locations where they are used to replenish eroded beaches and rebuild coastlines for protection of low-lying areas. Sand excavated from the ocean is used for beach restoration and land reclamation. This includes both the excavation and removal of a variety of materials – sediment, sand, rock and debris – from waterways, such as harbours, ports, lakes and rivers, usually for the purpose of deepening or cleaning them.
