Groove section determination method and device, medium and product

The invention discloses a grooving section determination method and device, a medium and a product, and relates to the field of inland waterway improvement. In the process of calculating the beach elimination hydraulic index, the calculation section is divided into different flow zones through the flow zone method, the heights and the widths of the different flow zones can be reflected, then the section form relation is reflected, meanwhile, the influence of the section forms formed after different grooving schemes are implemented on the grooving effect can be reflected, and the calculation accuracy of the beach elimination hydraulic index is improved. The defect that the previous beach elimination hydraulic index does not reflect the section form is overcome. 本发明公开一种挖槽断面确定方法、设备、介质及产品，涉及内河航道整治领域。本发明在计算消滩水力指标的过程中，通过采用流带法将计算断面划分为不同流带，可以体现不同流带的高度和宽度，进而反映出断面形态关系，同时，也可以反映不同挖槽方案实施后形成的断面形态对挖槽效果的影响，克服以往消滩水力指标没有反应断面形态的不足。
