| Sumario: | <p id="p1">A current field of research in the context of climate change is the morphological modification of the riverbeds where the undercrossing constructions of large-diameter pipelines are located. An excessive phenomenon of hydrodynamic erosion was studied for 18 years in a river bed with two arms, where the undercrossing of three pipes with diameters of 800–1000 mm is located. A hydraulic-mathematical model was created to simulate the phenomenon, especially the erosion depths on the watered perimeter. The research was carried out on a river section with a length of 420 m, width of 270 m, slope of 0.0876% slope, and water depth according to flow of 3.00–4.50 m. The model calculates parameters of the erosion phenomenon at the characteristic points on the watered perimeter of the river (tangential stress on the wetted perimeter, velocity at the wall, erosion depth, maximum diameter of the displaced particle, and others).</p> |
