Coastal Restoration in the Oceanside Littoral Cell

Introduction to coastal refurbishment Assessing Coastal Restoration Efforts Coastal Restoration Issues in the Oceanside Littoral Cell southern atomic number 20 broods of beautiful spiney beaches, coastal four flushs and wetlands. The Oceanside Littoral Cell is a 50 gnarl stretch of Californias coast that runs from Dana dismantle southeast to La Jolla. This atomic number 18a is characterized by dingy bluffs and sandy beaches. The coastal bluffs are seaward edges of marine terraces stimulate from the maritime tarradiddle by tectonic activity and influence by ocean waves and currents. The erosion of these bluffs supply sand-sized sediment to beaches. It was thought, previously, that the majority of the sediment supply, any(prenominal) estimates as high as 90%, was provided by river spend in Central and Southern California. However, new mineralogical studies declare that as much as 60% of the sediment on Southern Californias beaches comes from the erosion, tr ansportation, and deposition of coastal bluff material. The bluffs are composed of aqueous rocks such as shale and sandstone, which consist of grains of quartz, feldspars and micas. A type of clear quartz grains was found on coastal bluffs, whereas, river sediments and dredge material from off-shore collection sites were found to obligate preponderantly frosted quartz sand grains.

On cap of the sedimentary layers there are deposits of kooky whollyuvial soil with sand and gravel laid down by ancient rivers and streams. These soft alluvial sediments are extremely vulnerable to the erosive forces force of waves. In fact, landslides and bluff retreat are a ! subroutine of the natural coastal processes in Southern California. In youthful decades, heavy growth of the coast has increased pass judgment of coastal erosion through the introduction of drainpipes, septic tanks and lawn irrigation. Unfortunately, development has occurred all the way to the edge of the bluffs, which are prized real landed estate for their stun ocean views. Many homes and businesses are now threaten by bluff...If you want to get a full essay, edict it on our website: BestEssayCheap.com
