Abstract

In this paper, area and elevation differences derived from high-resolution digital elevation models (DEMs) are used to estimate the amount of sediment contributed by gully erosion. tHE AA. describe the methodology and errors involved in determining the amount of sediment produced by 11 gullies in the headwaters of the Waipaoa River basin, and assess the proportion of the total annual sediment load of the Waipaoa River supplied by the Tarndale and Mangatu gully complexes. The data pertain to rates of sediment production, rather than sediment yields, because the AA. have no means of reliably assessing sediment delivery ratios
