QUINTANA BEACH DUNE RESTORATION & BEACH NOURISHMENT
Town of Quintana, Texas
Quintana Beach is located on the Gulf of Mexico
about 65 miles
south of Houston. Due to a historical erosion rate of
approximately 15 feet per year, much of the beach and dune system
was severely eroded leaving existing homes and infrastructure
vulnerable to storm damage. Texas General Land Office (TGLO) and Town of Quintana (TOQ) requested Coast & Harbor Engineering (CHE) to design the beach and dune
reconstruction along it's most vulnerable locations.
Engineering services provided on this project included coastal engineering
analysis, upland sediment source search and location, preliminary/final
engineering design, and construction engineering services.
The project construction started immediately after permit acquisition in February 2005 and ended March 15, 2005, the start of the turtle nesting season along the Texas Gulf Coast. The complete project, from startup to construction, was completed in 8 months. CHE Engineers also developed a 3-year monitoring plan for estimating project renourishment rates.

CHE performed the following project tasks:
|
Data collection program was developed to obtain wind, wave, tidal elevation, bathymetric, topographic, and geologic data. |
|
Historical data was reviewed and analyzed to better understand geomorphology. |
 |
Performed Numerical Modeling (STWAVE and SBEACH). |
 |
Performed Feasibility level nourishment profile alternatives and provided recommendations to client. |
 |
Final Engineering design of project features including location and characterization of borrow source material, dune reconstruction, and beach nourishment. |
 |
Evaluated size and location for each of the components to optimize the performance and minimize construction cost. |
