TL;DR: Dredge sediments containing MPs were stored in piles on farmlands, whereby MPs were subsequently dispersed to surrounding soils and surface waters while awaiting a permanent disposal option.

TL;DR: In this article, the authors studied benthic colonization following physical disturbance in shallow brackish waters at the SW coast of Finland, northern Baltic Sea, and showed the stock of colonizing species and the immigration distance to be major structuring factors in macrozoobenthic community development.
Abstract: Benthic colonization following physical disturbance was studied in shallow brackish waters at the SW coast of Finland, northern Baltic Sea. Following sand suction and periodic stagnation an annual colonization pattern is described in relation to continuous succession following channel dredging. The importance of different colonization mechanisms is discussed. The number of species recovers faster than abundance and biomass, and recovery from dredging may take as long as 5 years. Experiments show the stock of colonizing species and the immigration distance to be major structuring factors in macrozoobenthic community development.

TL;DR: Dredging significantly reduced the N flux at the SWI, which was evident from the reduction of inorganic N release flux and N removal through denitrification and anammox, Therefore, sediment dredging has its advantages and disadvantages in managing internal N loading in lakes.

TL;DR: In this paper, the authors address the general acceptability of seasonal restrictions through a compilation of available information on physical-chemical environmental alterations associated with dredging and disposal operations, and critical information regarding the effects of these alterations on principal biological resources.
Abstract: Abstract : Seasonal restrictions on dredging and/or disposal operations are based upon concerns about potential dredging- or disposal-induced negative impacts to biological resources. In many cases, however, information on the degree to which either naturally occurring or dredging-induced environmental alterations directly or indirectly affect organisms is poorly quantified, in which case restrictions are based upon a reason to believe notion. This report addresses the general acceptability of seasonal restrictions through a compilation of available information on physical-chemical environmental alterations associated with dredging and disposal operations, and critical information regarding the effects of these alterations on principal biological resources. Based on this information, a method for evaluating existing or proposed seasonal restrictions on dredging and/or disposal operations is presented. This framework reflects the present understanding of effects of dredging- or disposal-induced, as well as naturally occurring, environmental alterations upon biological resources. In many cases, the magnitude of dredging- or disposal-induced alterations falls well within the range of naturally occurring phenomena and imposes little or no additional stress upon resource populations. In some cases, however, the magnitude of alterations may exceed that which occurs naturally, whereby concerns about dredging- or disposal- induced alterations are justified and should be considered when planning a project.

TL;DR: The limited impact of the sand extraction operation on the physical characteristics of the sediment and hydrological-sedimentary characteristics in the relict sand area should aid its rapid recovery and the restoration of the original community in a short period of time (2-4 years after dredging).
