Evaluate the Depth of Scouring of the Bridge Base Using Soft Calculation Techniques [PDF]
Advances in Engineering and Intelligence Systems, 2022 Scouring is caused by riverbed erosion by water flows and water-borne materials. In the present work, the depth of scouring is estimated using the autonomous neural network (SOM). The results have been compared to the results of other models.
