Some infected cats can remain without symptoms, yet act as carriers and spread the infection to other non-infected cats. The following symptoms may also be sporadic in a FHV-1 carrier: 1  Sudden, uncontrollable attacks of sneezing.  Watery or pus containing nasal discharge.
Beach Erosion. Beach erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).Storm waves carry the sand offshore, depositing and storing the sediment in large sandbars.each erosion occurs when waves and currents remove sand from the beach system. The loss of sand causes the beach to become narrower and lower in elevation (Figure 1).
Sand dunes only form where the rate of beach deposition is greater than erosion (positive sediment budget). Sand Dunes on Flamborough Head. When the dried sand reaches the top of the beach it can be trapped by debris such as driftwood, dead seaweed or rocks and pebbles.idge and runnel systems are formed due to the interaction of tides, currents, sediments and the beach topography. They only form on beaches with a shallow gradient. They form as a simple drainage route for tides. Water flows in and out via the runnel.
