Graduate Fellowship Description
M.Sc.Eng. (Geology) - Accurate definition of sediment layering of a reservoir.
One of the primary concerns with dam remediation is estimating the volume of sediment accreted since emplacement (45 years in the case of Mactaquac Dam). While the total volume may be large, spread over a large area the local thickness of the sediments may be very thin (decimeters). Digital subbottom profiling records acquired using broadband acoustic sources (28 kHz and 3.5 kHz) will be analyzed to define this layer as well as gravity cores to understand impedance contrasts and advance our interpretation of sediment layers.
The 3.5 kHz profiles are also expected to provide insights into the deeper stratigraphy (glacial and post-glacial) that will be controlling the groundwater flux during reservoir drawdown and potentially influencing engineering solutions for the future MD removal or renewal.
We will complement the acoustic survey with a towed low power seismic system to obtain greater depths of penetration and/or improved resolution in areas of particular interest.
Possible options include the IKB Seistec system previously proven for subbottom aquifer imaging at Fredericton or a sparker-based system capable of greater penetration in coarse sediments and tills. [Supervisor Dr. Karl Butler, UNB Fredericton]
Prospective candidates should email a cover letter, CV, unofficial university transcripts and contact information for three people who can serve as references. The cover letter must clearly indicate the project being applied for, and outline how the candidate’s previous experience has prepared him/her to function as a leader of the respective MAES study component, and what specific qualifications the candidate will bring to the large, multidisciplinary MAES Team.
Review of applicants for the projects starting in summer 2014 will begin 21 February 2014 and continue until the positions are filled. Ideal start date for 2014 projects is in March/April. For positions starting 2015, applications can be provided until fall of 2014.
Send complete application packages to Project Manager Gordon Yamazaki by email ([email protected]).
