Improved Technique For Controlling Oscillation Of Coastal Morphological Modeling System, Yun-Chih Chiang, Sung-Shan Hsiao, Ming-Chung Lin Dec 2011

Improved Technique For Controlling Oscillation Of Coastal Morphological Modeling System, Yun-Chih Chiang, Sung-Shan Hsiao, Ming-Chung Lin

Journal of Marine Science and Technology–Taiwan

Numerical modeling of coastal morphological evolution is a powerful tool for the planning and design of coastal engineering. The coastal morphological modeling system is based on the sediment conservation law, which couples modules for waves, wave-driven currents, and sediment transport rates. The numerical scheme for the sediment conservation law and nonlinear coupling between these modules can lead to dispersions, diffusions, spurious oscillations and instability problems that are still not well established. Filtering or artificial diffusion are often added to achieve stability. In this paper, several controlling oscillations schemes without filters are described. A stable morphological model is introduced with a …

Harmonic Decomposition By Hht On Regular Waves Propagating Over A Rectangular Submerged Obstacle Upon A Fluidized Bed, Yung-Lung Chen, Shiaw-Yih Tzang, Shan-Hwei Ou

Journal of Marine Science and Technology–Taiwan

The experimental measurements of surface waves over a submerged rectangular obstacle upon a sandy bed reported by Tzang et al. (2008) have further been analyzed in detail by Hilbert-Huang transform (HHT). The harmonic components of regular waves at 5 sites in the vicinity of the obstacle are decomposed into the intrinsic mode functions (IMFs) by the ensemble empirical mode decomposition (EEMD) with postprocessing scheme using masking signal EMD (MSEMD). The results of Hilbert spectrum of waves derived by the HHT illustrate that considerable decay of harmonic amplitude occurs at all 5 sites when the sandy bed have been fluidized but …

Influences Of Discharge Reductions On Salt Water Intrusion And Residual Circulation In Danshuei River, Wen-Cheng Liu, Wei-Bo Chen, Ming-Hsi Hsu Dec 2011

Influences Of Discharge Reductions On Salt Water Intrusion And Residual Circulation In Danshuei River, Wen-Cheng Liu, Wei-Bo Chen, Ming-Hsi Hsu

Journal of Marine Science and Technology–Taiwan

A three-dimensional, unstructured grid, hydrodynamic model was established and applied to study the salt water intrusion and residual circulation in the Danshuei River estuarine system of northern Taiwan. The construction of two reservoirs (i.e. Shihmen Reservoir and Feitsui Reservoir) and water diversion in the upper reaches of the river system significantly reduces the freshwater inflow. The changes had contributed farther to the intrusion of tidal flow and salt water in the upstream direction. The model was validated with available hydrographic data measured in 2001 then used to probe the change in salt water intrusion as a result of reservoir construction. …

Dynamic Coupling Of Multi-Phase Fluids With A Moving Obstacle, Tso-Ren Wu, Chih-Jung Huang, Mei-Hui Chuang, Chung-Yue Wang, Chia-Ren Chu Dec 2011

Dynamic Coupling Of Multi-Phase Fluids With A Moving Obstacle, Tso-Ren Wu, Chih-Jung Huang, Mei-Hui Chuang, Chung-Yue Wang, Chia-Ren Chu

Journal of Marine Science and Technology–Taiwan

In this paper, we present a two-way coupled moving solid algorithm with discrete element method (DEM) to simulate dynamic fluid-solid interaction. This model allows obstacles moving in the multi-phase fluids to generate realistic motion for both the fluids and obstacles. We discretize the NavierStokes equation using finite volume method (FVM) for the fluid part. The volume-of-fluid (VOF) method is used to track the fluid-fluid and fluid-solid interfaces. This algorithm is useful in the fields of Engineering and Earth Sciences, such as structure collapse and landslide generated tsunamis. Examples of landslide tsunami and floating cubes are demonstrated using the algorithm.

The Method Of Fundemental Solutions For The Multi-Dimensional Wave Equations, Meng-Huang Gu, Chia-Ming Fan, Der-Liang Young Dec 2011

The Method Of Fundemental Solutions For The Multi-Dimensional Wave Equations, Meng-Huang Gu, Chia-Ming Fan, Der-Liang Young

Journal of Marine Science and Technology–Taiwan

In this paper, a meshless method is developed for solving multi-dimensional wave equations. The proposed method is based on the method of particular solution (MPS), the method of fundamental solutions (MFS) and the Houbolt finite difference (FD) method. The wave equation is considered as a Poisson-type equation with the time-dependent source term. The Houbolt method is applied to avoid the difficult problems for dealing with the initial conditions in forming the linear algebra system. The works of space discretization are dependent on the method of particular solution and the method of fundamental solutions. There are three numerical examples considered in …

Aging Of Florida Blue Crabs, Callinectes Sapidus, Through The Biochemical Extraction Of Lipofuscin, Claire Elizabeth Crowley Dec 2011

Aging Of Florida Blue Crabs, Callinectes Sapidus, Through The Biochemical Extraction Of Lipofuscin, Claire Elizabeth Crowley

USF Tampa Graduate Theses and Dissertations

The blue crab, Callinectes sapidus, represents an ecologically and economically important component of marine and estuarine ecosystems. In Florida, blue crab landings accounted for $9.6 million dollars during the 2010 fishing season. Accurate stock assessments for this valuable fishery are essential. Age is a critical biological component of accurate stock assessments; however, blue crabs and other crustaceans are especially difficult to age because of the complex nature of discrete growth. Biochemical extraction of an aging pigment, lipofuscin, was developed using blue crab eyestalks. The current study investigated the effects of freezing preservation on lipofuscin extracts and examined whether the …
