Journal Article
Wu, X., Baas, J. H., Parsons, D. R., Eggenhuisen, J., Amoudry, L., Cartigny, M., …Ruessink, G. (2018). Wave ripple development on mixed clay-sand substrates: Effects of clay winnowing and armoring. Journal of geophysical research. JGR. Earth surface, 123(11), 2784-2801. doi:10.1029/2018JF004681

Based on bed form experiments in a large‐scale flume, we demonstrate that the rate of development of wave ripples on a mixed sand‐clay bed under regular waves is significantly lower than on a pure‐sand bed, even at clay fractions as low as 4.2%, and... Read More

The adaptation of dunes to changes in river flow (2018)
Journal Article
Reesink, A. J. H., Parsons, D. R., Ashworth, P. J., Best, J. L., Hardy, R. J., Murphy, B. J., …Unsworth, C. (2018). The adaptation of dunes to changes in river flow. Earth-Science Reviews, 185, 1065-1087. doi:10.1016/j.earscirev.2018.09.002

The dunes that cover the beds of most alluvial channels change in size and shape over time and in space, which in turn affects the flow and sediment-transport dynamics of the river. However, both the precise mechanisms of such adaptation of dunes, an... Read More

Laboratory study on the effects of hydro kinetic turbines on hydrodynamics and sediment dynamics (2018)
Journal Article

Experimental investigation of the impact of macroalgal mats on the wave and current dynamics (2015)
Journal Article

Macroalgal mats of Ulva intestinalis are becoming increasingly common in many coastal and estuarine intertidal habitats, thus it is important to determine whether they increase flow resistance, promote bed stability and therefore reduce the risk of e... Read More
