The major objective of this project is to develop an integrated smart platform for disaster reduction which seamlessly integrates information of hydro-metrology, fluvial-pluvial flood, soil erosion and landslide disasters in decision-making process. After analyzing the information, lesson learned center is built for disaster education and communication by employing various display tools. In the first and second year of this project, we have collected data such as: typhoons in the past, heavy rain events from the rainfall stations, meteorological satellite data of different bands, radar quantitative precipitation, historical positioning of the typhoon paths. Then, we have developed some simulation modeling systems for calibration and verification, and provided the system to collect information from multiple sources and to enhance the understanding of the flood potential. In the third and fourth year, we have completed several test cases, and planed presenting and visualizing disaster information. Main tasks during 2015 are as follows: (1)Hydro-meteorology under climate change research: In the nine actual disaster cases chosen, the calculated optimal rainfall threshold indicated a more timely and accurate early-warning of flood events; (2)Fluvial-pluvial flood research: Including levee safety evaluation due to climate change and risk map of dike failure for Kaoping River, integrated modeling of drainage and overland flow in Jhonghe, real time overland flow simulation using rainfall data from ensemble forecast system, application of flooding potential map on integrated disaster information platform, the 3rd-generation flooding potential map-an example of Kaohsiung City; (3)Soil erosion and landslide research: A case study of potential DF049 landslides stream is chosen to simulate and compare the sediments yields and movement before and after slope remediation; and (4)Presentation and visualization for disaster information: The flood decision support system is developed for improving the efficiency of the whole flood management process. The flood information platform is officially in operation which reveals another possibility that using Information Communication Technology (ICT) on disaster management.整合氣象水文水理土砂
