TL;DR: The authors examines how anthropogenic activity has caused significant changes in the quantity and quality of fine-grained sediment within river systems, using examples of: land use change in New Zealand; the effects of reservoir construction and management in different countries; the interaction between sediment dynamics and fish habitats in British Columbia, Canada; and the management of contaminated sediment in USA rivers.

TL;DR: In this article, the authors examined the sediment load in the Waipaoa River, New Zealand and in two of its tributaries (Mangatu and Te Arai Rivers) for evidence of different dominant erosion processes in the basins upstream.

TL;DR: The methodology and errors involved in determining the amount of sediment produced during two (19·5 and 33·2 year) periods by 11 (c. 0·01 − >0·20 km2) gullies within a 4 km2 area in the headwaters of the Waipaoa River basin, New Zealand, using sequential digital elevation models are described as mentioned in this paper.

TL;DR: In this paper, high-resolution digital elevation models (DEMs) were derived from sequential aerial photography of an active fluvio-mass movement (gully) complex in New Zealand's North Island East Coast region, to measure geomorphic changes over approximately one year.

TL;DR: The last postglacial transgression and present highstand of sea level were accompanied by a reduction in the terrigenous flux to the deep ocean bordering the active convergent margin off the eastern North Island of New Zealand as mentioned in this paper.
