U.S.-Philippines Cooperative Research on Development of a Predictive Capacity for the Occurrence of Large Amplitude Coastal Seiches

该提案要求资金允许博士。伍兹霍尔海洋研究所物理海洋系的David C. Chapman和地质与地球物理系的Graham H. Giese，与菲律宾大气、地球物理和天文服务管理局（PAGASA）国家大气科学研究所的Rolu P. encaracion先生进行为期24个月的合作，一项合作研究计划，以发展对大幅度海岸洪水发生的预测能力。合作者将获得从菲律宾巴拉望岛普林塞萨港到大陆架边缘的海平面振荡、水温和盐度的时间序列测量。从这些测量中获得的数据将输入到一个改进的数值模型中，并将输出与测量的泥浆特性进行比较。海岸海潮是一种长驻波，在港口、海湾和大陆架上经常观察到水位振荡，周期从几分钟到几小时不等。即使是很小的垂直运动也可能伴随着相对较大的水平运动，产生的电流可能使船只失去控制，导致碰撞或搁浅。建立了一个简单的两层模型，将内波对地震的激发与层化程度联系起来。该模型的输出将与实测的泥浆特性进行比较。本研究的最终目的是可靠地预测巴拉望岛的海啸。合作者是本研究领域备受尊敬的科学家。目前的项目将使他们能够结合他们的才能和兴趣，互惠互利。该项目与“发展中国家科学项目”的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美国科学家和工程师与发展中国家同行之间的合作水平。

This proposal requests funds to permit Drs. David C. Chapman, Department of Physical Oceanography, and Graham H. Giese, Department of Geology and Geophysics, Woods Hole Oceanographic Institution, to pursue with Mr. Rolu P. Encarnacion, National Institute of Atmospheric Sciences, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), for a period of 24 months, a program of cooperative research to develop a predictive capacity for the occurrence of large-amplitude coastal seiches. The collaborators will obtain time series measurements of sea-level oscillations and water temperature and salinity from Puerto Princesa Harbor, Palawan Island, Philippines, out to the shelf edge. Data obtained from these measurements will be input into an improved numerical model, and the output will be compared with measured seiche characteristics. Coastal seiches are long, standing waves that are frequently observed as water-level oscillations in harbors, bays, and over shelves with periods ranging from a few minutes to a few hours. Even small vertical motions may be accompanied by relatively large horizontal motions, producing currents which can carry ships out of control and cause their collision or grounding. A simple two-layer model has been developed which relates seiche excitation by internal waves to the degree of stratification. The output from this model will be compared with measured seiche characteristics. The ultimate objective of this research is reliable predictions of Palawan Island seiches. The collaborators are highly respected scientists in the field of this research. The present project will allow them to combine their talents and interests for mutual benefit. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
