The missing dimension: effects of lateral variation on 1-D calculations of fluvial bedload transport (2003)
Journal Article
Ferguson, R. (2003). The missing dimension: effects of lateral variation on 1-D calculations of fluvial bedload transport. Geomorphology, 56(1-2), 1-14. https://doi.org/10.1016/s0169-555x%2803%2900042-4

Most calculations of bedload transport in rivers, including those in numerical models of aggradation and degradation, are 1-D: all hydraulic and transport-rate calculations are averaged over the channel width. Because bedload transport laws are nonli... Read More about The missing dimension: effects of lateral variation on 1-D calculations of fluvial bedload transport.

Flow in meander bends with recirculation at the inner bank (2003)
Journal Article
Ferguson, R., Parsons, D., Lane, S., & Hardy, R. (2003). Flow in meander bends with recirculation at the inner bank. Water Resources Research, 39(11), Article 1322. https://doi.org/10.1029/2003wr001965

In highly curved river bends, flow may separate at the inner bank to create a recirculation eddy with weak upstream flow. Very little is known about how recirculation eddies connect with the downstream flow or how the latter is affected by their pres...

Assessing the credibility of a series of computational fluid dynamic simulations of open channel flow (2003)
Journal Article
Hardy, R., Lane, S., Ferguson, R., & Parsons, D. (2003). Assessing the credibility of a series of computational fluid dynamic simulations of open channel flow. Hydrological Processes, 17(8), 1539-1560. https://doi.org/10.1002/hyp.1198

Recent developments in numerical algorithms have enabled the construction of three-dimensional models for the prediction of flows in open channels. These advances encompass improvements in both numerical solutions and the process representation requi...

Emergence of abrupt gravel to sand transitions along rivers through sorting processes (2003)
Journal Article
Ferguson, R. (2003). Emergence of abrupt gravel to sand transitions along rivers through sorting processes. Geology, 31(2), 159-162. https://doi.org/10.1130/0091-7613%282003%29031%3C0159%3Aeoagts%3E2.0.co%3B2

Gradual downstream fining along gravel-bed rivers is often followed by a relatively abrupt change to a sand bed. This has usually been explained by the breakdown of pebbles of certain lithologies to sand, but it is not restricted to particular rock t...
