本計畫將以宜蘭地區淹水範圍監測系統為基礎架構，蒐集彙整轄區淹水相關資料及檢核，強化水位監測設備及資料維護，提昇即時淹水資訊系統，另擴充蘭陽溪流域防汛重點區域之淹水範圍監測模組，並應用水理模式初步建置淹水預警系統，提供即時淹水資訊，以研擬減災應變對策與掌握發佈預警之時機及提升救災效能。

Flooding disaster emergency could easily lead to significant loss of life and property of the people. Over the years the flooding situation have often informed by people or related personnel, resulting in missing the best time for disaster relief operations. The inundation situation cannot be immediately handled, such as flooding depth, inundation extent, and damage losses.The project continue the ongoing flood monitoring function of the Water Conservation Department’s First River Bureau of the Ministry of Water Resources in the "Renewal and Maintenance of Flooding Range Monitoring System for the Yilan Area in Year 104", and updated the regional real-time water level monitoring equipment and numerical terrain (DEM) ) To strengthen the immediate flood information assessment system and integrated geographic information system to help improve the accuracy of flood information in the disaster response to control real-time information and judged flooding to provide the most rapid flooding of information, Reduce the information gap caused by the development of the error situation, and by the establishment of the relevant information on the relationship between regional flooding.The immediate monitoring system for flood disaster is to provide timely flooding information by collecting topographic data of Yilan area, selecting suitable monitoring water level gauge or arranging small-scale recorder observation, and providing GIS information analysis and display platform so that decision-makers can fully and At the same time master the scope of the flooded areas and flooded depth; due to limited funding, Yilan yearly planning the main waterlogging area of the water level monitoring equipment, currently in Yilan River Meifu drainage 5 water level meter, Dongshan River 3 water level and The water level indicator of the Dekuchou Stream can be automatically monitored by automatic transmission, while some areas still need to perform flood monitoring by manual observation.Meifu drainage update mapping area of about 741 photos, covering an area of about 2 square kilometers, the production of 10 cm precision orthophoto and 0.7m × 0.7m DEM. When the flooding height is 50cm, the waterlogging area is about 15 km2, and the flooded area is about 12 km2 when the flooding height is 50cm, and the waterlogging area is about 15 km2. 15% of the treatment effectiveness indicators; flow comprehensive stage 1, flooding area of about 12 km2 down to 11 km2, 5% of governance effectiveness indicators. Take Meifu drainage as an example, the flooding planning stage, flooding height of 30cm, flooding area of about 5km2 down to 3km2, 40% of the treatment effectiveness index. Flooding area is about 30 km2; flooding height is 1m, flooding area is 20 km2, 10 km2 is flooding area, and control index is 10 ~ 15%, and the flooding area is about 30 km2. The flood control height was 20 ~ 60cm, the area decreased to 25 km2, the control effect was 10 ~ 15%; the flooding height was 1m, the area decreased to 11 km2, and the control effect index was 35%. In response to the web browser support issue, Silverlight has been reorganized into HTML5, which includes water and rainfall information, water level monitoring, warning water level, flood damage, disaster prevention maps and function menus, which can effectively improve system usability.This year there are four typhoons, including Typhoon Megi, which was more serious. On September 27, 105, Typhoon Meiji entered the land from the city of Hualien, which caused Yilan, Malika, Moranti and Meiji. Flooding situation in some areas of the region, through the system monitoring Meifu drainage area of about 242.89 hectares of flooded area, mostly in farmland area, the amount of the affected about 348.74 million.
