Analysis and optimization of river flood control and drainage problems based on ArcGIS
When the river flood control and drainage are not smooth,the downstream river will face huge flood disaster risks. In order to solve the problems that affect river flood control and drainage and ensure the safety of river flood control and drainage,it is necessary to analyze the river flood control and drainage capacity. Therefore,river flood control and drainage based on ArcGIS were analyzed and optimized. Taking Liaocheng City,Shandong Province as the research object,this paper first collected remote sensing images and administrative division data. On this basis,the paper used ArcGIS software for data processing and information extraction while delineating the range of spots with problems. Then,through on-site investigation and verification,the paper further improved the vector data,created a problem list,and proposed processing methods. Finally,the paper uploaded the spot images with problems,actively rectified them according to the processing methods,and ensured compliance through inspection,ultimately obtaining the resulting image. This paper aims to provide a reference for the investigation and effective disposal of river floods,improve the flood control and drainage capacity of cities,reduce the threat of flood disasters to people's lives and property,and ensure the safe and stable development of the social economy.
