[Lore] Longshore drift is the movement of sand and rock along a coastline caused by waves washing over a beach at an oblique angle . Wave diffraction describes the process that occurs when a wave encounters an obstruction in its path causing it to wrap around it and/or change direction. Refraction can also explain why waves tend to be larger off of points and headlands, and smaller in bays. Longshore current is the mean current along the shore between the breaker line and the beach that is driven by an oblique angle of wave approach (see Figure 5.17). This difference in wave energy also explains why there is net erosion on points, while sand and sediments get deposited in bays (see section 13.3). C. thermocline; pycnocline B. A. gneiss a. An optimized split-window algorithm was used to invert the Yangtze Estuary's temperature field during a cold wave process. A region has just had a 100-year flood. The periodic fall and rise in levels of water as a result of gravitational force of the sun and moon would result in, Littoral drift, which results in gradual sand movement down the beach in the same direction is also referred to as, Along an irregular coastline, areas most intensely under attack by waves are. In this proof-of-concept study, we apply the same framework to three datasets: the first, a set of close-range monochrome infrared (IR) images of individual nearshore waves at Duck, NC, USA; the second, a set of visible (i.e. Figure 12.37. The movement of sand parallel to the shore is crea c. there is no difference in the relative proportion of oxygen isotopes The speed at which waves approach the shore depends on sea floor and shoreline features and the depth of the water.
