Coastal regions are very important because they provide a lot of resources and benefits for all the humankind. Coastal defense structures protect coastal regions from wave attacks. However, the cost of construction such coastal defense structures are very high and need big investments. Hence, to reach the optimum design and minimize the risk of failure has vital importance during the design stage of these structures. Model studies are the most effective tool in optimizing the design of these str...

Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. Aerosol-sink modelling is of importance to the global-scalecontext, because sink strengths influence the concentration of aerosol particles in the atmosphere, and that concentration, in turn, influences climate. Dry deposition models are insufficient due to...

The coast of Louisiana, with more than three million wetland acres, accounts for about 40 percent of the nations total wetlands. Louisiana is estimated to have lost more than 1.2 million acres of its coastal wetland in the last century. Although 75% of Louisianas coastal wetlands are privately owned, little has been done to encourage private landowners to undertake wetland restoration projects. This dissertation examines the factors that influence the decisions of the landowners to undertake wet...

Tropical cyclone impacts on wetland, terrestrial, and shelf systems have been previously studied and reasonably delineated, but little is known about the response of coastal lakes to storm events. For the first time, tropical cyclone impacts on a shallow coastal lake in the Louisiana coastal plain have been studied using direct lines of evidence and numerical modeling. Using side-scan sonar, CHIRP subbottom and echo sounder bathymetric profiles, the lake bottom and shallow subsurface of Sister L...

Spotted seatrout, Cynoscion nebulosus, are common in estuaries and coastal waters of the south Atlantic and Gulf of Mexico and are of considerable recreational and economic importance. Still, the spatial ecology of this species is under-studied and poorly resolved, especially in Louisiana waters. To address this important knowledge gap, I examined the movements, distribution, and habitat use of adult spotted seatrout in coastal Louisiana primarily using high-resolution acoustic telemetry and sec...

Two severe Hurricanes, Katrina and Rita, caused devastating damages in the northern Gulf of Mexico during late summer and early fall 2005. Louisiana was the most heavily impacted state, where both storms made initial landfall. The storms caused billions of dollars in damages to public and private infrastructure, with particularly strong impacts to coastal fishing businesses. Numerous assessments of coastal fisheries infrastructure damage were developed by state and federal agencies following the...

<p><br>The use of in-stream wetlands is a growing practice being used to mitigatethe impacts of non-point source (NPS) pollution. Wetlands promote physical,chemical, and biological processes that attenuate and convert nutrientswhich can lead to improved water quality. Wetland performance is sensitiveto site conditions, making it difficult to precisely quantify their possibleimpact. Factors such as site specific soil, hydrologic, and vegetativecharacteristics influence wetland effectiveness. Typi...

The response on the continental shelf of a baroclinic ocean to driving by an alongshore coastal wind stress and by barotropic and baroclinic wind forced interior motions is studied as a function of latitude. The relative excitation of continental shelf waves and internal Kelvin waves is studied. The response of a rotating stratified ocean with a vertical boundary, forced at the surface by an alongshore coastal wind stress, shows vertically propagating subinertial motions. Several examples which ...

A two-dimensional numerical mesoscale model, which ic1udes radiative and turbulent transfers, has been constructed to study the formation, development and dissipation of coastal stratus cloud under an inversion. In the model, the delta-Eddington and emissivity approximations are used for the solar and thermal radiative transfers, respectively. K-theory parameterization is adopted for the turbulent transfer. Ground surface temperature and moisture are predicted using the methods of Deardorff (197...

Observations of wind, currents, sea level and hydrography obtained during the 1972 Coastal Upwelling Experiment (CUE-I) are described. Only phenomena with periods longer than a day are considered. One section describes the changes observed during a period of variable winds in early July 1972. Another describes a ribbon of relatively cool water observed early in the upwelling season and attributes its existence to advection of Subarctic water by the coastal jet associated with upwelling. A third ...

Short-term changes in the distribution, surface to 10 meters, of phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and Cu) were studied in the near-shore waters off Humboldt Bay, California, through the summer of 1971. The depth distribution of phytoplankton-associated trace metals was related to local hydrography. During periods of upwelling higher concentrations of phytoplankton-associated Fe, Mn, Cr, and Zn were found at depth (10 meters) than at the surface. During periods of no...

Temperature, salinity, and dissolved oxygen concentration measured in an estuary were analyzed to determine if the effects of coastal upwelling could be observed and used to effectively monitor the degree of upwelling. Hydrographic data collected weekly at a point four miles from the entrance of Yaquina Bay (Buoy 15) were analyzed for their applicability as indicators of coastal upwelling. Only data collected during the known upwelling season off Oregon of May through October were considered. Lo...

Relations between the diversity of juvenile anadromous salmonids and pool features were examined in a managed and a pristine watershed in Oregon during the summer of 1990. There were no differences (p>0.05) in pool depth, velocity or pool wood volumes between streams. However, the pristine system had twice the number of pools within similar lineal distances. Pools in the pristine system also had larger substrates (percent dominant within pools) and smaller pool area (p=0.01). Fish diversity was ...

The condition of the herring (Clupea harengus) in the Baltic Sea has decreased during the past 30-40 years. This decrease could be explained by different factors; (1) change in diet due to changes in zooplankton community, (2) changes in water temperature and salinity, (3) increasing nutrient inputs and (4) competition for food with other species such as sprat (Sprattus sprattus). In this study the change in condition was analysed using the Fulton’s condition index, and by looking at age and sex...

As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which they interact over time frames of thousands of years. They form a large-scale template that constrains the character of aquatic habitat, controls the effects of di...

Since its introduction in 1956, the use of open-system, diel dissolved oxygen curves for estimating the components of ecosystem metabolism in the lotic setting have been important in determining the current ecosystem theory of streams, both spatially among multiple systems and longitudinally within the same system, as well as identifying potentially impaired systems, especially when contrasted with streams considered unimpaired. Several factors have been identified as controls on both components...

A study of phosphorus loading and water quality implications was conducted for the Oregon coastal lakes. The study was based on existing data for lake total phosphorus concentrations and for watershed land uses. A phosphorus mass-balance model was developed to predict lake total phosphorus concentrations from estimated phosphorus loading from land uses within the lake's watershed. Uncertainty in total phosphorus concentration estimates are included in the model, and model predictions are conside...

The structure and function of coastal marshes results from a complex interaction of biotic and abiotic processes that continually influence the characteristics of marsh vegetation. A great deal of research has focused on how tidal processes influence vegetation dynamics along the Atlantic coast, but few studies have investigated the influence of similar processes in the marshes along the Gulf of Mexico. This study aims to identify the characteristic vegetation assemblages of the coastal marshe...

Real-time wave forecasts are critical to a variety of coastal and offshore opera- tions. NOAA’s global wave forecasts, at present, do not extend into many coastal regions of interest. Even after more than two decades of the historical Exxon Valdez disaster, Cook Inlet (CI) and Prince William Sound (PWS) are regions that suffer from a lack of accurate wave forecast information. This dissertation develops high- resolution integrated wave forecasting schemes for these regions in order to meet the c...

The Texas-Louisiana Shelf Circulation and Transport Study featured moorings that covered the shelf during 1992 to 1994, and captured the oceanic response on the shelf to category 4 Hurricane Andrew in August of 1992. Eighty-one current meters distributed over 31 moorings along several contours of isobaths provided excellent spatial and temporal coverage over the shelf. The low-frequency variability (2 days and longer) of current observations and tide gauges to the West of the storm are analyzed ...

In the past few years, there has been an increase in the number of hurricanes hitting the Gulf of Mexico coastline. These hurricanes have caused damage in the billions of dollars, and hundreds of people have been killed during these events. The damage from hurricanes is caused by four main factors: storm surges, waves, strong winds and rain. At the coast, the damage due to the storm surge and waves is dominant. Numerical simulation models like ADCIRC are available for estimating storm surge, but...

Most of the coastal areas around the globe depend on coastal aquifers vulnerable to salt water intrusion. The Salalah plain in southern Oman is underlain by a shallow limestone aquifer extending north up to the foot of the Jabal AlQara which reach a height of about 1000 m. A major part of the recharge to the aquifer is through fog condensation on the forest on the upper slopes of the mountain. Increasing population and water use for agriculture has caused limited salt-water intrusion. There is a...

Managing contaminated urban coastal areas is an important issue in today’s society. Harbor areas are transformed from industrial sites and shipyards, to housing areas with high environmental requirements. The use of coastal areas for aquaculture and fishing activities increases the need for cleanup of previous contamination sources. High environmental standards when handling dredged material from harbors and industrial activities are also required in our society today. Many countries including N...
