Residents and Seal Beach officials urged a state task force to find a solution to the expensive problem of sand erosion that eats away at the city’s coastline, reports losalamitos.patch.com.
At a community meeting Members of the Coastal Sediment Management Work Group presented their plan for dealing with longshore drif.
Without replenishment Seal Beach could disappear. During the entire meeting, members of the Coastal Sediment Management Work Group demanded that Seal Beach gets high priority.
Coastal erosion is the wearing away of land and the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Waves, generated by storms, wind, or fast moving motor craft, cause coastal erosion, which may take the form of long-term losses of sediment and rocks, or merely the temporary redistribution of coastal sediments; erosion in one location may result in accretion nearby. The study of erosion and sediment redistribution is called ‘coastal morphodynamics’. It may be caused by hydraulic action, abrasion, impact and corrosion.
