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 paper, the performance of 12 bed load sediment transport formulae developed for use in gravel bed channels was evaluated and the results showed that no formula consistently performs consistently well and the limitations of the test data, the constraints imposed by an operationally realistic test, and reasons based upon the physics of the transport phenomenon all may be adduced.

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: In this paper, a modification of Hamamori's (1962) probability distribution function, generated by Monte Carlo simulation, was presented, which permits one to specify the sampling interval, in relation to the length of a bedform.

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.
