“…At about assumed characteristic distance, the difference in recent sedimentation rates achieved by 210 Pb analysis in 2 gravity cores (i.e. cores 6 and 7 off the southwest coast of Hai Hau) is only 0.5 cm/y (van den Bergh et al, 2007). Therefore the assumption is acceptable.…”

“…The position of sampling stations was determined using a GPS with an accuracy of 5-100 m. A total of 52 sediment samples were taken by grab sampler. This is a part of investigation in the Red River coast in 1996 and 2000 (referred to Duc et al (2007)). …”

“…Erosion along the Hai Hau and Hau Loc coastlines can be attributed to the prevalent southwestward longshore currents at depths of less than 5m and southward currents between 10 and 30m depth [4]. Duc et al [4] described the Hai Hau coastline as behaving like a "high-wave energy coast" (p. 564), and the continued high rates of erosion, similar oceanic current systems and the geomorphology of the Hau Loc coastline indicates a similar environment.…”

“…It is still unclear that human activities such as construction of channels, dykes and dams have impacted on the coastline change [4], although Seto and Fragkias [7] and Thao [11] showed that aquaculture pond development and plantation of mangroves could facilitate coastline accretion. Thanh et al [9] indicated that a range of human activities, such as river damming, irrigation practices, dyke building, river channel dredging, mangrove destruction and mining practices, would played a significant role in the observed coastline changes.…”

We conducted a mineral magnetic study of river bank and subaqueous delta sediments from the Red River, in order to examine the role of sedimentary sorting on the variation of sedimentary magnetic properties from source to sink. The magnetic mineralogy mainly consists of magnetite and hematite. Bulk sediment particle‐size variations have a strong influence on magnetic properties, with the frequently used magnetic parameters χfd%, χARM, χARM/χ, and χARM/SIRM exhibiting positive correlations with the <4 µm fraction, while S‐ratios are negatively correlated with this fraction. Compared with river bank sediments and shallow shoreface (<5 m water depth) sediments, sediments from the deeper (>5 m water depth) part of the subaqueous delta have lower χ and SIRM values, a finer ferrimagnetic grain‐size and higher proportions of hematite, consistent with selective loss of coarse ferrimagnetic grains on the source‐to‐sink pathway. We suggest that variations in magnetic properties in response to particle‐size compositions and therefore depositional environment changes should be carefully addressed when magnetic proxies such as χARM/SIRM are used in the study of coastal and marine environmental changes (e.g., sea‐level change). In such cases, the combined use of magnetic properties and geochemical indicators, such as Al/Ti ratio, may provide better results for paleoenvironmental reconstruction.
