ABSTRACT

The Gueyon reservoir, situated at Yeongchon region, Kyongbok, is prime water storage facilities for agricultural purposes. This reservoir, built by earthen dam and managed by state authority, suffered an embankment failure on August 21, 2014. Every year during monsoon, heavy rainfall causes deterioration and collapse of small earthen dams possess a serious threat to the safety and wellbeing of surrounding rural areas. It may also weaken the soil and lead to a piping and structural failure. This paper discuss the use of low cost Unmanned Aerial Vehicle (UAV) based remote sensing system for post-disaster assessment and monitoring of reservoir embankment failure. For reservoir management, a software was developed for acquisition, post processing and analysis of UAV-based aerial imagery. It used a streamline workflow comprising flight planning, data-acquisition, post processing and finally with precise topographical information an accurate Arial image and ortho-rectified map has been created. Product of UAV aerial imagery work are truly beneficial and content richer information which can be more helpful for decision support system.
