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.

Mobile, Alabama –  The ability of communities to recover from natural and manmade disasters is strongly linked to the resilience of their infrastructure. That is why the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) announced yesterday that it has awarded a $20 million, five-year agreement with Colorado State University and 10 other partners, including the University of South Alabama, to establish the Community Resilience Center of Excellence. Click on the logo (top right of post) to link to the Center web site.

 

The goal of the Center is to develop a risk-based approach to evaluate potential strategies that improve the resilience of the built environment to natural hazards and other significant manmade disruptions.

 

The resilience tools that the Center develops will address known and frequent hazards, and gauge the ability of communities and the built environment to adapt to changing conditions and recover quickly from large-scale disasters.

 

The University of South Alabama’s Department of Civil Engineering will provide their unique coastal engineering expertise related to hurricane storm surge and waves. Drs. Bret Webb and Scott Douglass will help develop risk-based tools that address vulnerability and resilience of the built environment to coastal hazards like storm surge, waves, erosion and even sea level rise. Webb and Douglass recently authored nationwide engineering guidance for assessing the exposure and vulnerability of coastal transportation infrastructure to extreme events.

 

“With well over 50% of the U.S. population living within 50 miles of a coastline,” says Dr. Webb, who is an Associate Professor of Civil Engineering, “much of our nation’s critical infrastructure is vulnerable to coastal hazards and the expected impacts of long-term sea level rise.”

 

“What’s more troubling,” Dr. Webb continues, “is that demand in these coastal areas is increasing, putting more stress on our built environment and underscoring the need for improving the resiliency of our coastal communities.”

 

Dr. Scott Douglass, Professor of Civil Engineering, added, “Based on both experience and study, we understand that the built environment along our nation’s shorelines is highly vulnerable today, and will face increased pressures due to the expected impacts of climate change in the future.”

 

“However, the good news,” Dr. Douglass continued, “is that making our coastal infrastructure more resilient to frequent storm events today will also reduce their vulnerability in the future.”

 

With authorization from NIST to begin their efforts immediately, the multi-disciplinary research team, which also includes experts from California Polytechnic University (Pomona), Rice University, Texas A&M University (TAMU), TAMU-Kingsville, and the University of Washington, is expected to hold their first organizational meeting soon.
