Abstract:
Sand hoppers (Amphipoda: Talitridae) are semiterrestrial crustaceans that feed upon stranded kelp. Their burrowing behaviour plays an important role in reintroducing nutrients into the sediment. The most abundant sand hopper on New Zealand’s beaches is Talorchestia quoyana Milne-Edwards, 1840. It is host to a parasitic mermithid nematode, Thaumamermis zealandica Poinar, Latham and Poulin, 2002, which invariably kills its sand hopper host by emerging to complete its maturation and reproduction in a moist sand environment. The aim of the present study was to assess if the burrowing behaviour of

Abstract:
The matter of the quantification of the fraction of the dredged sediment that is released by a trailing suction hopper dredger into the surrounding waters, also known as the passive phase of the plume during dredging operations through the overflow, is a rather complex process. A number of processes, including sediment settling, propeller wash, and entrapment of air during sediment release, are only a few of the reasons why plumes are formed and sediments because of the overflow are released back into the environment.

Abstract:
Dredging of fine sediments and dumping of fines at disposal sites produce passive plumes behind the dredging equipment. Each type of dredging method has its own plume characteristics. All types of dredging operations create some form of turbidity (spillage of dredged materials) in the water column, depending on (i) the applied method (mechanical grab/backhoe, hydraulic suction dredging with/without overflow), (ii) the nature of the sediment bed, and (iii) the hydrodynamic conditions. A simple parameter to represent the spillage of dredged materials is the spill percentage (Rspill) of the initi

The rate of soil detachment by water flow indicates soil erosion intensity directly.

In a coastal environment, this paper investigated the formation process and the cumulative shape of subaqueous mounds formed by hopper dredged discharges.

Particular attention was paid to the formation of the mounds, the three-dimensional shape and the influence factors. The field measurements showed that the mounds were roughly symmetrical

Abstract:
Convential models for the erosion of non-cohesive sediments overestimate the erosion rate induced by high flow velocities. These high flow velocities occur, for instance, in breaching of embankments or dunes (flow velocities up to 10 m/s) or in jetting sand with a trailing suction hopper dredger (30 to 60 m/s). At these very large flow velocities the erosion process is significantly influenced by the properties of the soil mass (non-cohesive particles). Governing parameters at higher flow velocities are dilatancy, permeability and the (un)drained shear strength of the soil. The sediment concen
