Embodiment 1

[0041] Such as figure 1 As shown, the rapid calculation system of the cross-sectional area of ​​the river channel of the present invention includes an unmanned survey ship 6 and a control and calculation terminal 12 . The control and computing terminal 12 includes a control module and a computing module. The control module communicates with the unmanned ship for sending movement position instructions to the unmanned ship; the calculation module communicates with the unmanned ship for receiving the longitude and latitude position information obtained by the unmanned ship and combining them with river water level information The built-in channel feature parameters and channel DEM data extract the channel section calculation parameters corresponding to the current latitude and longitude information, and calculate the channel cross-section area according to the calculation model.

[0042] The ship-borne RTK 7 is installed on the unmanned ship 6, and the ship-borne RTK 7 includes ...

Abstract

The invention discloses a method and a system for quickly calculating the area of water-passing cross section of a river channel, and belongs to the technical field of water conservancy project management information. According to the method, existing river channel characteristic parameters and DEM data are built in a control and calculation terminal in advance, and latitude and longitude position information and river water level elevation data are obtained at the center position of a specified river section by using an unmanned measuring ship loaded with RTK; dEM data are compared, parameters such as river bottom elevation, floodplain and left and right bank slope elevations of corresponding longitudes and latitudes are extracted, the river channel water-passing section calculation method based on the river channel elevation and the river channel water level is established, the current river channel water-passing section area can be quickly obtained through the calculation method and fed back to a user, and the hydrographic survey efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy project management information, in particular to a method and system for quickly calculating the cross-sectional area of ​​a river channel. Background technique [0002] The area surrounded by the water surface line and the river bottom line at a certain research moment is called the cross-section. The cross-section is a cross-section perpendicular to all the streamlines of the primary or total flow. The water cross section is not necessarily a plane, and its shape is related to the distribution of streamlines. Only when the streamlines are parallel to each other, the water passing section is a plane, otherwise it is a curved surface. The determination of the cross-sectional area of ​​the water is mostly calculated from the measured cross-sectional diagram of the water. If the vertical and horizontal scales of the cross-sectional diagram are the same, it can be directly measured by pl...
