The project on investigations of natural disasters in the Philippines was proposed by INCEDE considering the large amount of natural disasters experienced in the Philippines and the heavy damage they cause. INCEDE invited researchers from the University of Philippines, Philippines Atmospheric Geophysical and Astronomical Services Administration (PAGASA), Philippine's National Mapping and Resources Information Authority (NAMRIA), to participate in the project. During the first meetings held in the Philippines, flood disaster mitigation was identified as the focus area of the research.Flood disaster mitigation requires flood forecasting, and identifying the risk involved. If measured rainfall and river discharge for a long period are available, conceptual mathematical models can be used to forecast flood and relate it to the risk. However, this approach does not work if there are not enough observations, or if the catchment characteristics change very much during the period of calibratio … More n. Both of these factors are common in the Philippines. Therefore, it was decided to construct and apply a Physically based distributed hydrologic model to a selected catchment, and then to use the results to develop a simplified mathematical model for ungauged catchments for operational purposesDuring the project, two hydrological models, a fully distributed model and a physically based lumped model, were constructed at INCEDE.Agno Catchment in the Luzon island was selected as the study area, and PAGASA carried out hydrologic data compilation while NAMRIA carried out digitizing work to construct the GIS.for the Agno River Basin. A researcher from the National Hydraulic Research Center (UP), visited INCEDE to participate in setting up the model for the Agno river basin. A GIS consisting of Digital Elevation. Model of the basin, SPOT satellite images (and landuse derived from it), soil map, population distribution and the road network was constructed. During the project 12 Philippine researchers have been invited 18 times to Japan to participate in discussions, workshops and field visits.The model application showed good results in simulating past floods. The GIS can be used together with the flood forecasts from the simulation model to arrive at disaster mitigation strategies. The resuls including GIS and models will be handed over to Philippine counterparts in due course. Less

菲律宾自然灾害调查项目是由国家环境与发展研究所提出的，考虑到菲律宾经历了大量的自然灾害及其造成的严重破坏。INCEDE邀请菲律宾大学、菲律宾大气地球物理和天文服务管理局（PAGASA）、菲律宾国家测绘和资源信息管理局（NAMRIA）的研究人员参与该项目。在菲律宾举行的第一次会议上，减轻洪水灾害被确定为研究的重点领域，减轻洪水灾害需要进行洪水预报，并确定所涉风险。如果可以获得长期测量的降雨量和河流流量，则可以使用概念数学模型来预测洪水并将其与风险联系起来。然而，如果观测量不足，或者在校正期间集水特征变化很大，这种方法就不起作用。 ...更多信息 n.这两个因素在菲律宾都很常见。因此，决定构建一个基于物理的分布式水文模型，并将其应用于选定的流域，然后利用其结果开发一个简化的数学模型，用于未测量的流域，以供运行时使用。在该项目中，INCEDE构建了两个水文模型，一个完全分布式模型和一个基于物理的集总模型。吕宋岛的阿尼奥流域被选为研究区域，和菲律宾大气、地球物理学和天文学服务管理局进行了水文数据汇编，而美国国家测绘和资源信息管理局则进行了数字化工作，以便为阿尼奥流域建立地理信息系统。国家水利研究中心的一名研究员访问了INCEDE，参与建立阿尼奥流域的模型。一个由数字高程组成的地理信息系统。建立了流域模型、SPOT卫星图像（以及由此得到的土地利用）、土壤图、人口分布和道路网。在该项目期间，12名菲律宾研究人员18次应邀到日本参加讨论、讲习班和实地考察，模型应用在模拟过去的洪水方面取得了良好的效果。地理信息系统可以与模拟模型的洪水预报一起使用，以制定减灾战略。包括地理信息系统和模型在内的成果将在适当时候移交给菲律宾对应方。少
