Geophysical assessment of Lime/Clay grout injection of estuary and reservoir embankments subject to badgers burrows erosion
According to studies, 46 % of dams and embankments failures are due to severe internal erosion (Foster et al., 2000). Animal burrowing can lead to a preferential path for the water flow and seepage through the flood embankments that could lead to a partial or total collapse of the structure. Geophysical survey can provide additional information about water seepage pathway that could inform Geotechnical analysis on the failure mechanisms of embankments and the influence of animal burrows in the process as well as quality control of remedial grout injection of lime and clay.
General Aims: To inform the risk of badgers burrows network based on Geophysical conductivity/saturation mapping of river, estuary and reservoir embankment slopes. To assess the efficiency and completion of repair grouts injections inside the badgers setts.
• To establish a map of the burrows network inside embankments slopes at different depths (0.5m increments) covering the common thickness of transitional landslides and embankments slope slip surface and landward face failure after overtopping or seepage.
• To identify the zones at risk based on conductivity/saturation levels compared with local point measurements (Geotechnical)
• To use Electrical Resistivity Tomography Inversion and Ground Penetrating Radar to refine the conductivity model of the sub-layers of soil from the CMD mini-explorer results
• To provide a risk evaluation map based on Geophysical and Geotechnical existing sensors data and slope stability softwares (Geoslope etc…)
• For the methodology to be adopted by companies like Atkins and Mott Mac Donald and by the Environment Agency for reservoir safety and river embankments integrity long term monitoring.
You must have, or expect to achieve, at least a 2:1 honours degree or international equivalent, in Civil Engineering or a relevant subject. Experience conducting both numerical and experimental/field test research would be an advantage, but is not essential. The candidate will be expected to conduct work with international academic partners and should have good interpersonal skills.
An overall score of IELTS 6.5 or equivalent is required, with individual scores of 6.0 in each of the four sub-skills: writing, reading, speaking and listening.
