As an island, Taiwan is especially sensitive to the impact of the global climate change. Due to the influences of global warming
and climate change, coastal floods will be more and more frequent over Taiwan areas. The action of the strong wave force ortyphoon force often causes many destroy of seawall, for example the eroded caves behind seawall. This damage not only affects
the lives of residents behind seawall, but also causes the severe flooding in coastal area.
This proposal presents an application of the Ground-Penetrating Radar (GPR) to detect the failure potential of eroded caves ina seawall. The seawall structure site survey was selected at Chi-Gu seawall in Tainan. From a series of GPR tests, it was foundthat the position of the eroded caves in a seawall can be easily identified using GPR

This paper presents the beach safety assessment indicators to assess the safe area for beach recreation. The sea area safe forreaction is defined by the beach security assessment indicators, including wave height, beach type, tidal elevation, sea velocity andbeach shifting sand. According to the results, wave height, beach type and tidal elevation are major important indicators affecting
personal water height. Seawaters flow field is an important indicator of change in location during the recreation process, andbeach shifting sand is an important indicator affecting the beach air quality in the recreation area. Based on the considerationof the above influencing factors, this paper proposes to delineate the recreation areas by beach rating method. In this paper, asseawaters affect the tidal wave and current, MIKE 21 HD hydrodynamic model and SW wave model are used to simulate thenearshore wave and current characteristics. With Fulong Beach in northern Taiwan as the site for analysis, this study compares
the model computation results and the in-situ observation data proposed by Lin (2009). The simulation of in-situ observation
data is consistent in terms of the split current generation position. In summary of the discussion on beach safe recreation areaof Fulong Beach by applying the above assessment methods, it is found that the beach safe recreation area is 0-30m line duringhigh tide and 0-90m line during low tide.

ABSTRACTThe issue of low energy independent rate has been a serious problem in Taiwan, while while the development of renewableenergy is an important energy policy at present to solve the energy problem. Offshore Renewable Energy is the most potentialpart of Taiwanese renewable energy resources, and at this stage the Taiwan government has also been active in promoting thedevelopment of offshore wind farms. However, another issue is marine spatial multi-use that indirectly affect the building ofoffshore wind farm. The main reason is overlapped between the development of sea and important ecosystems, and due to thelong-term neglect of ecosystem conservation that was led to protest the development of offshore wind farm. In order to balance
between ecosystem conservation and the development of offshore wind farms, this study focuses on the case of demonstration
offshore wind farm, and we are especially from the perspective of ecosystem services to re-examine the development of the sea,and then through four service of ecosystem to analyze the services that provided from the ecosystem of demonstration offshore
wind farm, as well as the benefits of these services to the stakeholder. From the results, we found that ecosystems provide
many services to the stakeholders, and the stakeholders also gain a lot of benefit from the services of ecosystems. Due to theeconomic value of ecosystems is not priceless, but can not be estimated. If we pay attention to the sustainability of ecosystems,
the renewable energy development would truly achieve the objective of sustainable utilization.

The numbers of students enrolled in ocean-related departments are statistically studied in this paper. Data of three academicyears, 2001, 2005 and 2010, are analyzed and compared. All of these departments are classified into four groups: marine science,ocean engineering, marine navigation and other related departments. It is found that the total number of students increases quickly
from 2001 to 2010 at all level of academic degrees. Moreover, some new departments which include ocean tourism, ocean culture
and general marine affairs are established in recent years as more applications and job opportunities of ocean affairs appear.

Compiling textbooks of ocean science for students under age eighteen
LIU, Chi-min1∗

In Taiwan, ocean-related courses and textbooks designed for students under age 18 are quite limited at each level of school.
There are two reasons for this phenomenon. One is that the ocean knowledge is not seen as a basic science subject in comparison
with physics, chemistry and biology. Another reason is that most experts and researchers work at the college level rather thanhigh schools and under. To deepen the education of ocean science for younger students, textbooks entitled as Ocean science,technology and history suitable for students for senior and junior high schools, and elementary schools are compiled by theauthor. Different from textbooks used in universities and colleges, it requires more delicate strategies and vivid descriptions
which are obviously beyond an academic ability of professors. To this end a team including teachers at different levels of schools
is established to edit textbooks. Experiences that the authors acquired in editing this textbook are represented herein. Theyinclude how the structure of chapters was chosen, how the figures for easy comprehension were painted, and how the difficultand hard sentences were translated to simple expressions.

For both undergraduate and graduate students who are interested in fundamental theories of earth science, mathematical tools
play an important role for understanding basic equations in many academic fields. In this paper, mathematical tools applied
to derive the Boussinesq equations with viscous effects are introduced to elucidate the relation between applied mathematics
and earth science. Mathematical techniques used are the scale analysis, the perturbation method and the Pade approximation.
Parameters for measuring nonlinearity, dispersion effects, density ratio and viscous effects are also defined. Based on thesedefinitions as well as mathematical methods, viscous Boussinesq equations for internal waves are derived and analyzed. Strong
connections between mathematics and earth science are also demonstrated.
Keywords: scale analysis, perturbation method, Pade approximation, viscous Boussinesq equations
