With the vigorous development of science and technology,the level of waterway maintenance and management in our country has been significantly enhanced.Under the new pattern of the comprehensive advancement of the “four verticals,four horizontals and two networks”,in response to the uneven development of waterway management and maintenance technology in our country,the current status of waterway management and maintenance technology development in each region during the 14th Five-Year Plan period is systematically sorted out,and the development situation and core demands of waterway management and maintenance technology during the 15th Five-Year Plan period are studied.By combining case analysis and data induction,it is shown that different innovative management and maintenance technologies have been explored and practiced in various river basins and regions across the country,but a system and standard have not yet been formed,and the overall level still needs to be improved.Facing the 15th Five-Year Plan period,the integration of intelligence and digitalization should be taken as the main line,green and low-carbon transformation as the orientation,and the improvement of the standardization system as the support.The full life cycle management model should be comprehensively popularized,and scientific and technological innovation and application research in key areas such as safety risk prevention and control,intelligent prevention and early warning,and efficient emergency response should be deepened,so as to enhance the efficiency and sustainability of waterway management and maintenance.
