washout of the bottom Explanation: 6. Washout of the bottom and exploited banks of of Kheu River were successfully avoided below the discharge channel of the hydroelectric plant in the alternate left-bank scheme with the passage of flows to 65 m3/sec. https://link.springer.com/article/10.1007/BF02765771 We provided the contractor with guidelines about the need to monitor local washouts, as bridge failures and disasters often caused by washout of the bottom at https://www.egis-group.com/projects/south-vistula-bridge |

[underwater] bed/shoreline scouring Explanation: https://www.wrl.unsw.edu.au/news/awash-with-issues-managing-... -------------------------------------------------- Note added at 23 mins (2024-03-29 18:20:50 GMT) -------------------------------------------------- Shallow water turbulence and bottom scouring is a factor for several of the ports, so this vessel incorporates controllable pitch propellers - https://www.marinelink.com/news/delivered-ferry-woods413022 -------------------------------------------------- Note added at 9 hrs (2024-03-30 03:05:01 GMT) -------------------------------------------------- Manoeuvering thrusters (bow thrusters and stern thrusters) are transversal propulsion devices built into or mounted to either the bow or stern (front or back, respectively) of a ship or boat to make it more manoeuvrable. - https://en.wikipedia.org/wiki/Maneuvering_thruster -- Scouring processes due to manoeuvring actions can produce big consequences on the stability of harbour structures such as docks and protecting dikes. - https://core.ac.uk/download/pdf/157811612.pdf -- Moreover, new range of propulsion types (e.g. propellers, bow-thrusters, podded propulsors, azimuthing thrusters, waterjets) can also increase the scouring action - https://upcommons.upc.edu/bitstream/handle/2117/131225/MAY_2... --- Hydrodynamic scour involves the erosion of seabed material and degradation of underwater structures by currents and waves. In a maritime terminal, the bottom material of the port and a variety of installations, including berths, quays, piers, and seawalls, are vulnerable to a number of forms of scour. - https://synthetex.com/blog/why-you-must-have-proper-scour-pr... |
