Large scale features accumulate on depositional coast

  1. 1. LARGE- SCALE FEATURESACCUMULATE ONDEPOSITIONAL COAST.
  2. 2. Sand spit deposition landform found off coast. spits grow, salt marsh develop as water being sheltered. Form where longshore current slow. Slow current  deposition of sand and gravel at downcurrent of headland. Curled  cause by wave refraction. Spurn point
  3. 3. Bay mouth bar sand spit attach to headland. adjacent to bay. protect the bay.Inlet Narrow body of water. At sea coast connection between bay and ocean. Bay mouth bar
  4. 4. Beach and baymouth bar at the mouth of the Russian River at Jenner
  5. 5. Barrier island Sand bar exposed and parallel to shoreline. Sediment accumulate on submerged rise. develop most easily on wave dominated coasts with a small to moderate tidal range. Migrate toward land as sea level rise. Severe storm generate intense waves  erode barrier island.
  6. 6. Lagoon Long, shallow body of water separated from large body of water. Isolated from ocean by barrier island or reefs. Become island  high land of coastal dunes. Sea level increase  island & lagoon increase toward land. Garabogaz – Gol lagoon in Turkmenistan
  7. 7. Sea island Firm central core. Part of mainland when sea level decrease. Sea level increase  surround with beach. Tombolo  sediment accumulate from bridge between sea island and mainland. Kelambu beach, Kudat Sabah
  8. 8. Drumlin and moraines Form by melting glacier. The Bride Hills (terminal moraine), Europe.
  9. 9. Deltas Deposition of sediment found at river mouth. Broad continental shelf present  as a platform Condition : -river transporting a large amount of sediment. -sea have a small tidal range and weak currents. -shallow at the river mouth. Shape represent balance between erosion and deposition.
  10. 10. TYPE OF DELTARiver-dominated Wave- dominatedStrong flow of fresh Smaller than river Tide-dominatedwater and continental dominated and tide Tidal current moresediment. dominated. strong than fresh water.Protect marginal Sooth shoreline. Sediment form longseas. Have one main exit island parallel to waterWell develop of channel. flow.distribution cause splitend of river.
