What Causes Longshore Drift – MyWaterEarth&Sky
WebOct 3, 2024 · Longshore drift is a geological process responsible for transporting sediments such as shingle, silt, clay, and sand along a coast that is aligned to the shoreline, relying on prevailing oblique winds. The … WebLongshore transport in the surf zone is primarily driven by wave-generated longshore currents generated by wave breaking and may be aided by wind-generated currents, particularly during storms, when wind, and wave direction are often coincident (Figure 18 ( … foods with low phytates
