Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons (2017)
Journal Article
Azpiroz-Zabala, M., Cartigny, M. J. B., Talling, P. J., Parsons, D. R., Sumner, E. J., Clare, M. A., …Pope, E. L. (2017). Newly recognized turbidity current structure can explain prolonged flushing of submarine canyons. Science Advances, 3(10), e1700200. https://doi.org/10.1126/sciadv.1700200

Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations. We seek to understand the internal structure and behavior of turbidity c... Read More

An evaluation of the use of a multibeam echo-sounder for observations of suspended sediment (2017)
Journal Article
Simmons, S. M., Parsons, D. R., Best, J. L., Oberg, K. A., Czuba, J. A., & Keevil, G. M. (2017). An evaluation of the use of a multibeam echo-sounder for observations of suspended sediment. Applied acoustics. Acoustique appliqué. Angewandte Akustik, 126, 81-90. https://doi.org/10.1016/j.apacoust.2017.05.004

The theory relating the acoustic backscatter from suspended sediments to the mass concentration of particles has been developed over several decades and is now routinely applied to provide measurements for commercial and scientific applications. Sing... Read More

Modelling tidal stream turbines in a three-dimensional wave-current fully coupled oceanographic model (2017)
Journal Article
Li, X., Li, M., McLelland, S. J., Jordan, L. B., Simmons, S. M., Amoudry, L. O., …Thorne, P. D. (2017). Modelling tidal stream turbines in a three-dimensional wave-current fully coupled oceanographic model. Renewable energy, 114, 297-307. https://doi.org/10.1016/j.renene.2017.02.033

© 2017 The Author(s) A tidal turbine simulation system is developed based on a three-dimensional oceanographic numerical model. Both the current and turbulent controlling equations are modified to account for impact of tidal turbines on water velocit... Read More
