The Nakdong River Estuary Barrage (NREB) prevents salt-water intrusion but causes sedimentation problems in the Lower Nakdong River in South Korea. Its mitigation requires mechanical dredging to maintain the flood conveyance capacity during typhoons. This analysis focuses on the possibility of replacing mechanical dredging with sediment flushing through gate operations changes at NREB. The new ...

An evaluation was made of the effects of dredging on the soft bottom community in the channel of the Rio Grande harbor in the Patos Lagoon estuarine region of southern Brazil. During four seasonal cruises, samples were collected from nine biological stations, one of which was located outside the dredged area. Three macrobenthic samples were collected on each cruise from each station, using a 0....

Suppose there is a given data set and there are a huge number of hypotheses [1] about this data set [2]. If the data is totally random, then say all the hypotheses are actually false. However, owing to the sheer number of hypotheses on a limited data set, it is possible to see some very highly correlated [3] data that are statistically significant [4]. In such cases, data dredging is said to ha...

The federal channel at Port of Miami, Florida, USA, was dredged between late 2013 and early 2015 to widen and deepen the channel. Due to the limited spatial extent of impact-assessment monitoring associated with the project, the extent of the dredging impacts on surrounding coral reefs has not been well quantified. Previously published remote sensing analyses, as well as agency and anecdotal re...

This document reviews the results of a workshop on scallop biology and the effects of scallop dredging on benthic communities. The workshop was held in Kodiak, Alaska, during 10-12 June 1999. A review of the history of the Alaskan weathervane scallop fishery was presented. Other speakers presented papers on scallop biology and fisheries in other cold-water areas. Topics of the papers included p...

Dredging of contaminated sediments has shown to be a harmful activity for the environment, because a number of contaminants can be resuspended and become available to the organisms. Furthermore, dredged contaminated sediments may cause significant damages in the dumping site. In order to avoid the drawbacks of this activity, better techniques have to be developed and the present article present...

The effect of dredge capture on the escape response ž / of the great scallop, Pecten maximus L. : implications for the survival of undersized discards Abstract The effect of simulated dredge capture on the swimming escape response of the great scallop, Pecten maximus, was assessed in order to determine the potential for mortality in undersized discards. Three experiments were carried out: first...

Piles and diaphragm wall supported berthing structure on marine soils are loaded laterally from horizontal soil movements generated by dredging. The literature on the adequacy of the finite element method modeling of berthing structure to analyse their behaviour during dredging and under earthquake condition is limited. This paper describes the finite element approach for analysing the lateral ...
