[0029] S2. Based on the general plan layout of the river, determine the river structure category of each area of ​​the river, and obtain the corresponding BIM parametric components from the component library based on the river structure category.

[0030] In this embodiment, the component library contains BIM parametric components corresponding to each type of river channel structure. By classifying and analyzing different types of river channel forms in detail, parametric component design and planning are carried out for each type of river channel structure, and components are established based on BIM technology.

Parameterization rules are set in the script to ensure the accuracy and completeness of the model, including the generation of river curves and the adjustment of the slope of the side slope.

[0037] S4. Based on the preliminary BIM model of the automatically created information integration, the model is adjusted and improved to obtain a three-dimensional BIM model of the river.

[0038] In this embodiment, the initially generated BIM model is checked and adjusted to ensure the accuracy and completeness of the model; the model is refined (adding details of the river boundary, improving the performance and realism of the model, etc.) and improved according to the actual situation, and necessary detailed information such as river hydrological information is added; finally, a three-dimensional BIM model is obtained, which can be used for the design, construction and management of river projects.
