WebAs it leaks, magnetic flux (magnetic field) will collect ferromagnetic particles (iron powder), making the size and shape of the discontinuity easily visible. However, the magnetic flux will only leak out of the material if the discontinuity is generally perpendicular to its flow. In a river, groynes slow down the process of erosion and prevent ice-jamming, which in turn aids navigation. Groynes run generally perpendicular to the shore, extending from the upper foreshore or beach into the water. All of a groyne may be underwater, in which case it is a submerged groyne. See more A groyne (in the U.S. groin) is a rigid hydraulic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. … See more Beach evolution and sedimentation accretion A groyne gradually creates and maintains a wide area of … See more • Similar • Beach erosion and accretion • Integrated coastal zone management • Erosion • Longshore drift See more • Groynes in the Netherlands • Channel Coastal Observatory - Groynes • Yossef, M.
