1) Field survey on hydraulic and water quality environments in Manila Bay-Laguna Lake coupling system and development of numerical simulation modelsIntensive field surveys were performed at Manila Bay, Laguna Lake and Pasig River in 2001 October (wet season), at Laguna Lake in 2002 February (dry season) and at Manila Bay 2003 February (dry season). With these surveys, the characteristic features of the hydraulic and water quality environments in these periods were clarified. Especially, the importance has been revealed for the effects of the spatial non-uniformity of the wind field on Laguna Lake, the environmental loads from the tributaries of the Pasig River through the Metro Manila area, the 3-D structure of the currents in Manila Bay and others. Further, by conducting a long-term continuous field measurement at Laguna Lake and Pasig River for the period from March to June, 2002, it was succeeded in observing the phenomenon that the brackish water from Manila Bay intrudes into the L … More aguna Lake in the end of the dry season. In addition to these field surveys, it was also attempted to develop numerical simulation models for currents in Manila Bay and Laguna Lake, respectively. For the former, with the basis of dual-sigma POM, a 3-D current model by Nadaoka & Nihei, nesting techniques and the effect of non-hydrostatic pressure distribution were examined. For the latter, on the other hand, a field survey to examine the hydrodynamic effects of the fishpen was conducted in Laguna Lake in 2003 March.2) Field survey on distributions and sources of heavy metals in relation to surrounding watershedsAnalyses have been made for the existing samples of bottom mud taken in Manila Bay and newly obtained bottom mud samples taken in Pasig River and Laguna Lake, revealing the characteristic distributions of various heavy metal components and their possible source areas. Special attention has been paid on the lead, as its distribution may show appreciable human effects. As one of the possible sources of the lead, roadside dust was sampled and analyzed.3) Numerical simulation of mudflow in Mt. Pinatubo watershed areaA two-dimensional numerical model of mudflow was developed and applied to the watershed area of Mt. Pinatubo, giving reasonable results. Less

1)马尼拉湾-拉古纳湖耦合系统水力和水质环境现场调查及数值模拟模型的建立马尼拉湾、拉古纳湖和帕西格河分别于2001年10月(丰水期)、2002年2月(枯水期)、2002年2月(枯水期)和2003年2月(枯水期)进行了大量的实地调查。通过这些调查，弄清了这些时期的水力和水质环境的特征。特别是揭示了风场的空间不均匀对拉古纳湖的影响、帕西格河支流流经马尼拉地区的环境负荷、马尼拉湾海流的三维结构等的重要性。此外，通过2002年3-6月在拉古纳湖和帕西格河进行的长期连续野外观测，成功地观测到了马尼拉湾微咸水侵入L…的现象在旱季结束时会有更多的奥古纳湖。除了这些实地调查外，还试图分别开发马尼拉湾和拉古纳湖水流的数值模拟模式。对于前者，在Nadaoka&Nihei的三维水流模型Dual-Sigma POM的基础上，考察了嵌套技术和非静力压力分布的影响。另一方面，2003年3月在拉古纳湖进行了现场调查，考察了鱼塘的水动力效应。2)现场调查了与周围流域有关的重金属分布和来源。对马尼拉湾现有的底泥样品和新采集的帕西格河和拉古纳湖底泥样品进行了分析，揭示了各种重金属组分的特征分布及其可能的源区。铅受到了特别的关注，因为它的分布可能会显示出明显的人类影响。作为铅的可能来源之一，对路边粉尘进行了采样和分析。3)山体泥石流数值模拟。建立了泥石流的二维数值模型，并将其应用于马鞍山分水岭地区。Pinatubo，给出了合理的结果。较少
