In the process of intelligent monitoring of siltation sections in plain river channels,surveying and mapping data is generally used to construct a water body model of the river channel,so as to analyze and obtain monitoring results.However,this process ignores the impact of surveying and mapping data noise on monitoring results,resulting in low accuracy of monitoring results.Therefore,a method for intelligent monitoring of siltation sections in plain river channels based on remote sensing surveying and mapping technology was proposed.Firstly,monitoring points for remote sensing surveying based on the direction of the plain river channel were set up,and consistent spectral band areas within the same monitoring point were merged through judgment.Secondly,two one-dimensional Fourier transforms were performed to remove surveying and mapping data noise.Finally,According to the denoised surveying and mapping data,the sediment carrying capacity coefficient of the plain river flow was calculated,and the relevant balance equation was used to obtain the monitoring results of the elevation of the siltation section in the river channel.The experimental results show that the monitoring results of the elevation of the siltation section in the plain river channel obtained by the method proposed in this article are highly consistent with the actual results,and the monitored siltation amount is highly consistent with the actual siltation amount.The monitoring results have high accuracy and can fully meet the actual needs of the management of the siltation situation in the plain river channels.
