1세부과제 :기상이변·기후변화 대응 농경지 침수피해 평가 및 대응 기술 개발
Purpose&Contents
Establishment of service system for farmland inundation forecast caused by weather anomaly and climatic change

Results
As a result of analyzing flood damage characteristics using flood trail, weather and spatial data of agricultural land, inundation occurred in order of drainage delay due to insufficient drainage ability > river flooding > runoff and sea flooding. To develop flood damage assessment technology using remote sensing technology,

We could identify flooding area through the backscattering number of radar satellite image and reflection characteristic of NIR band of UAV image. In the case of unmanned aerial photographs, it is possible to provide input data of inundation simulation model through DSM as well as detection of inundation area, and it can be used for production of land cover such as crop classification do. In addition to the exposure that can be calculated through hydrological modeling for flood risk assessment, risk assessment using image data based on remote exploration can be supported to establish policies for proactive response to flood damage and to establish countermeasures

Expected Contribution
It will contribute to mitigation of flood damage in rural watershed by predicting and informing flooded areas in rural watersheds due to weather and climate change.
Based on the results of the research, it will be useful to establish measures for flood mitigation in rural watersheds.
