This mechanism indicates that carbonate terraces and platforms in the Bonaparte Gulf can be the source of carbonate sediments, generating the variation of geochemical signal in the core.
On one hand, in the northwest, the porous aquifers of sandstone and unconsolidated sandy sediments generate soils with medium to sandy textures and little organic matter, forming geosystems that, despite having the wells with the highest yields, have low specific yield contributions to the rivers during the driest periods (Q 7,10 lowest yield for a period of 7 days with recurrence of 10 years).
Thus, although the postglacial period represented a time of high terrigenous sediment generation and delivery, only ~ 30% of the sediment generated by channel incision from Waipaoa catchment probably reached the marine shelf and slope of the Hikurangi Margin during this time.
The Pedra de Fogo Formation is composed of sedimentary rocks — rocks that are formed from sediment, generated by the erosion of older rocks, which was redeposited elsewhere.
This paper presents a retrospective assessment of sediment generated by slope failures following a single storm in March 1995.
It can consequently be deployed in remote, inaccessible areas to collect sediment generated through hillslope erosion processes as a means of testing predictions of erosion.
Furthermore, water bar structures were effective in trapping coarse sediment generated from skid tracks but markedly less so for fine <63 μm material.
Such an input-output modelling approach is applied in this paper for the first time to the modelling of dredged sediment management where the sediment generated becomes the input to a beneficial use project.
Sediment generated by postglacial channel incision represents only ~ 25% of the total sediment yield from this landscape with ~ 75% of the estimated volume of the postglacial storage offshore probably derived from hillslope erosion processes following base-level fall at times when sediment yield from these catchments exceeded storage.
The objectives of this study were as follows: a) to measure runoff and sediment generated from the surface and underground in the karst bare slope; and b) to analyse the impacts of underground pore fissures and bedrock bareness rates on soil erosion.
