Some of the usual suspects in Alabama and Mississippi have been busy developing technical guidance on living shorelines. What’s different about these new documents is that they are aimed at property owners and contractors instead of practitioners, scientists, engineers, etc. Our goal, as a community of living shorelines practitioners, has been to push some of our knowledge down to these underserved groups in hopes that they might make use of our regional general permits for living shorelines in Alabama and Mississippi.

Well after a couple of years of hard work (and some delays), I’m happy to say that they are finally available. Please click on the links below to download the PDFs. These projects involved too many friends and agencies to list here in this post, so please be sure to review the acknowledgments in each document. However, I would like to express our collective gratitude to the primary funding agencies (NOAA and GOMA) as well as the Mobile Bay National Estuary Program and the Southern Environmental Law Center for their support and hard work.

Pres-cover-pageThe latest study out of our ACES center (Applied Coastal Engineering & Science) is now available. The study, entitled “Lake Forest Mapping: Analysis of Shoaling and Pool Volumes,” was recently completed for the Lake Forest Property Owner’s Association and the City of Daphne with contracting support provided by the Mobile Bay National Estuary Program. The goals of the study were to determine how much sediment has accumulated in the Lake Forest lake (reservoir) since the time of dam construction in 1973/1974, where the largest accumulations of sediment have occurred, and what the remaining normal pool volume is within the lake.

We collected over 12,000 new elevation measurements within and around the lake to map the sediment elevations and also analyzed eight (8) shallow sediment push cores from the lake bed. The results of the study show that over 300,000 cubic yards of medium to coarse grained sediments have accumulated, or shoaled, within the present-day lake shoreline since 1973/1974. Approximately 80% of the lake has shoaled by some measurable amount since the time of dam construction, with some areas accumulating over ten (10) feet of sediment! As a result, the pool volume of the lake has decreased by about 60% due to the accumulation of sediments. The remaining volume could perhaps accommodate another 90 years of sediment input at the current reported rate of 7800 tons per year (as per Cook & Moss, 2008[1]), but the margin for error is quite large.

I presented these study results at a recent Mobile Bay National Estuary Program’s Project Implementation Committee Meeting. A copy of that presentation [2] can be downloaded {here}.  A copy of the final study report [3] can be downloaded {here}.  Please include proper attribution and/or citation [2,3] when reusing these data, results, graphics, and/or figures.

Our manuscript entitled “Spatial Variability of Hydrodynamic Timescales in a Broad and Shallow Estuary: Mobile Bay, Alabama” has been published by the Journal of Coastal Research. The manuscript is currently available online as a pre-print. The final version with color will be available in the coming months. Please {click on this link} for access to the manuscript.

The results presented in this new manuscript by Webb and Marr (2016) were initially developed as part of Chris Marr’s thesis research back in 2013. This new manuscript presents a much more narrow focus of his work and some new analyses as well. For more information about this work please review the {thesis} by Marr and/or this previous {blog post}.

 

 

 

I am searching for an undergraduate student to assist with coastal engineering research. I currently have one opening for a paid undergraduate research assistant position in spring 2016. Continuation of the research position will be contingent upon the receipt of additional funding.

 

The research assistant will be permitted to work up to a maximum of 20 hours per week for a maximum wage of $9/hour. Initially, the assistant will work for 10 hours per week at a wage of $8.50/hour. The duties of the research assistant will be:
 

1) to conduct and complete original coastal engineering research as assigned by the supervisor
2) to assist with laboratory experiments
3) to assist with field experiments

 

Those interested in this research position must submit a printed resume (no page limits) and statement of interest (max 1 page) to Dr. Webb by December 1, 2015. Applications by email will not be considered. The statement of interest must address, at a minimum, the following items:

 

A) your interest in coastal engineering
B) your current academic standing (GPA)
C) your schedule for spring 2016
D) any other on-campus and/or off-campus employment*

 

*Note: you must disclose any and all existing or planned employment for spring 2016 (excluding this position). Your application will not be considered if item D is not specifically addressed in the statement.

The Department of Civil Engineering at the University of South Alabama is seeking to fill a funded Graduate Research Assistantship for a student interested in pursuing a Master of Science in Civil Engineering degree, or a Doctor of Science in Systems Engineering, with concentrations in structural and/or coastal engineering. The initial appointment is for one year (1/2016 – 12/2016) and renewal will be contingent upon quarterly performance reviews (for up to three years ending 12/2018). The position will be competitively funded with a stipend and tuition. The qualified applicant should have an earned BS or MS degree in civil engineering by 12/31/2015, have an interest in coastal and/or structural engineering, and meet all admission standards of the Graduate School, and Department of Civil Engineering, at USA. Applicants should prepare the following materials and upload them to Academic Jobs using the link below: (1) brief statement of interest, (2) resume, (3) university transcripts, (4) a list of three references, (5) a technical writing sample, and (6) GRE and TOEFL/IELTS scores (if applicable).

Position

 

The successful candidate will be appointed to a Graduate Research Assistant position at the University of South Alabama (USA) in the Department of Civil Engineering and will be expected to pursue a Master of Science in Civil Engineering (MSCE), or a Doctor of Science in Systems Engineering, in the specialty areas of coastal and/or structural engineering. The University of South Alabama is a public university in Mobile, Alabama and the campus is located 30 miles from the white-sand beaches of the Gulf of Mexico. The MSCE program at USA focuses on civil engineering in the coastal environment and department faculty research expertise includes the traditional areas of water resources, environmental, transportation, geotechnical and structural engineering as well as coastal engineering.

 

Research

 

The research responsibilities of the student will be to assist in a five-year funded research project focused on improving the resiliency of the built environment to disasters and natural hazards. The project requires original research, laboratory work, numerical analysis, and interpretation of results. The student will perform physical modeling of wave-structure interactions in our new 25-meter wave channel. Additional project details will be made available at an appropriate time. The ideal candidate will:
1) Have demonstrated knowledge of common numerical analysis software (e.g., Matlab)
2) Have demonstrated experience working in a laboratory
3) Have experience or the ability to learn 3D rendering software (e.g., SolidWorks)
4) Be familiar with 3D printing (rapid prototyping) and conventional fabrication techniques
5) Be physically capable of performing their duties in the laboratory facility
6) Be able to travel to meetings and conferences
7) Be legally able to attend school in the United States without sponsorship or travel assistance
