Topographic
and bathymetric surveys were completed in the San Luis Pass area,
a natural tidal inlet on the southeast Texas coast. The detailed
survey data acquired by lidar and ground and echo sounder systems
using geodetic GPS positioning will be combined to create a seamless
digital elevation model (DEM). The DEM will serve as the base for
a geoenvironmental map describing the various depositional environments
and associated habitats of the tidal-inlet system.
The Texas General Land Office is funding this study because tidal
inlets play a variety of critical roles. They serve as passageways
for commercial and recreational vessels, as well as marine life
and nutrients. Tidal inlets affect water quality in the coastal
bays, and deposition of sediment near inlets forms foundations for
intertidal habitats. Inlet processes are also fundamental controls
on the littoral sediment budget and, hence, affect shoreline change.
Full understanding of coastal erosion problems along the Texas coast
must include examination of processes occurring at the 13 open inlets
and several more that are periodically open. |
