项目摘要

In these years , the heavy flood disasters were occurred at several countries in South-east Asia and the Pacific. The reasons of these heavy flood disasters were not only by meteorological change but also by land use pattern change caused by highly urbanization. The loss of natural infiltration areas and expansion of impervious areas affect the water cycle in the urban areas resulting in increased peak discharges and reduced river low flows. Impact of urbanization on hydrological cycle were analyzed through the data analysis and field observation.For these research , it is important to arrange the basic information of water resources and hydrological data. The river catalogues for South-east and the Pacific were published and it is useful for comparative study in these regions. The Asian FRIEND can be used for our research works, then we supports the activity of AP-FRIEND .This research group proceed the comparative and process research using data sets nominated in River catalogue.1)Urban hydrological cycle and its improvement measures.2)Long term analysis of precipitation trend caused by urbanization process and meteorological change.3)Collection and arrangement of river and basin digital data set for establishment of data base network in Japan rivers.4)Foreign investigator proceed the collection and arrangement of river data for River catalog Vol.3.5)Field observation of several countries were performed and collect the basic data and proceed the comparative study of river and hydrological characteristics.6)Flame establishment of data network and AP-FRIEND(Flow Regimes International Experimental and Network Data).7)Investigate the 98s flood disaster of Changjiang River in Chaina and compared to Japan flood disaster.

近年来，东南亚和太平洋地区的一些国家发生了严重的洪涝灾害。造成这些特大洪涝灾害的原因，除了气象变化外，还与高度城市化引起的土地利用格局变化有关。自然渗透区的丧失和不透水区的扩大影响了城市地区的水循环，导致高峰流量增加和河流低流量减少。通过资料分析和实地观测，分析了城市化对水文循环的影响，其中水资源基础资料和水文资料的整理是研究的重要内容。东南和太平洋的河流目录已经出版，对这些区域的比较研究很有用。Asian FRIEND可以用于我们的研究工作，本课题组利用《河流目录》中推荐的数据集进行了对比和过程研究：1）城市水文循环及其改善措施; 2）城市化过程和气象变化引起的降水趋势的长期分析; 3）城市化过程和气象变化引起的降水趋势的长期分析。收集和整理河流和流域数字数据集，用于建立日本河流数据库网络。4）外国调查员进行河流目录Vol.3.5的河流数据收集和整理。对多个国家进行了实地观测，收集了基础数据，并进行了河流和水文特性的对比研究。6）数据网络和AP-FRIEND的火焰建立7）对98年长江洪水灾害进行了调查，并与日本洪水灾害进行了比较。
