Polish term

podmycie dna

Polish to English Tech/Engineering Construction / Civil Engineering
Artykuł dotyczy inspekcji hydrograficznych dna akwenów wodnych.

(...) Regularne inspekcje minimalizują ryzyko awarii i ograniczają występowanie potencjalnych szkód, takich jak naruszenie konstrukcji nabrzeża w wyniku podmycia dna (spowodowanego okresowym uruchamianiem pędników zacumowanej w pobliżu jednostki pływającej).

washout of the bottom

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.

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

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...
