Predicting when sediment will move in a river is fundamental to successful management\u00a0of that river, which includes coping with floods, maintaining navigation, and preventing\u00a0loss of banks through erosion. However, after over 100 years of research our models of\u00a0sediment transport still do not perform well when applied to natural channels. Growing\u00a0evidence suggests this may be at least partially because we have failed to take into\u00a0account the effect that river-dwelling animals, especially invertebrates, can have on the\u00a0mobility of the sediment on the river bed and banks. Signal Crayfish (Pacifastacus\u00a0leniusculus) are an internationally significant invasive species that has serious detrimental\u00a0impacts on native ecological communities. In addition, they can burrow extensively into\u00a0river beds and banks, altering the structure and mobility of river sediments. In this project,\u00a0you will use existing measurements of coarse and fine sediment transport in the presence\u00a0of crayfish to adapt and construct sediment transport formulae to model sediment\u00a0dynamics in rivers infested with crayfish. These models will be tested against field data\u00a0collected during the project at sites in Northamptonshire in collaboration with the\u00a0Environment Agency and experiments performed by you at the Royal Netherlands\u00a0Institute for Sea Research. The resulting model will be used to investigate sediment\u00a0transport and changing channel morphology under differing invasion scenarios. You will\u00a0join an international network of academics and management professionals focusing on\u00a0better integrating ecology into our knowledge of river processes and sediment transport\u00a0and your pioneering work will contribute towards the shift from a purely hydraulics-based\u00a0approach to erosion and deposition in rivers, to one that takes an eco-hydraulic\u00a0perspective. Students will receive training at the University of Nottingham in all the\u00a0required data-collection and analytical and modelling techniques, and participate in the\u00a0structured NERC Envision training programme.<\/p>\n
Applicants should hold a minimum of a UK Honours Degree at a good 2:1 level or\u00a0equivalent in subjects such as Geography, Engineering, Mathematics, Environmental\u00a0Science, Earth Science or Natural Sciences.<\/p>\n
