With the rapid development of social economy, the development and utilization rate of land around rivers in our country is increasing, and the number of buildings facing rivers is increasing day by day, and some rivers are seriously encroached, resulting in increased pressure on flood control. In addition, the chaotic and unreasonable layout of the riverside buildings along some rivers, the increase of water blocking rate, and the private establishment of river-related buildings without the consent of the management department are very prominent, which has threatened the safety of the river and made the work of river flood control work increasingly pressured. big. According to the requirements of Article 38 of the "Water Law of the People's Republic of China", Articles 27 and 33 of the "Flood Control Law of the People's Republic of China", and Article 11 of the "Regulations of the People's Republic of China on River Management", during the flood When constructing non-flood control construction projects in floodplain areas and flood storage and detention areas, when the feasibility study report is submitted for approval, the project construction plan shall be reviewed and approved by the relevant water administrative department, and the flood impact assessment report reviewed and approved by the relevant water administrative department shall be attached. .
According to Articles 2 and 5 of the "Related Provisions on the Management of Construction Projects within the River Management Scope", all construction projects for new construction, expansion and reconstruction within the river management scope shall submit application documents to the river management authority in accordance with the procedures and management authority. According to the current development of river demarcation projects, the management of river-related construction projects has become more stringent, and it is urgent to provide technical training on flood control evaluation for technical personnel engaged in flood control evaluation and consultation across the country, so as to solve the technical bottlenecks encountered in actual work.
The lecturers are from key universities and scientific research institutes. They have been engaged in the establishment and application of flood control evaluation models for a long time, participated in the development and implementation of actual engineering projects, and have rich practical experience and a deep understanding of related software tools. . Proficient in flood control simulation software such as HEC-RAS, and has rich experience in software operation and its application in actual engineering.
