Beach Erosion Causes Impacts And Restoration

Coastal erosion is not the only impact of river sand mining.

Beach erosion causes impacts and restoration. Beach and coastal erosion ceases upon installation of the patented technology. As a consequence development along ocean shorelines entails substantial risk of property loss. Coastal erosion is a result of human activities and natural environment changes making the coastal dynamic action wave current wind lose balance in the coastal process and the long term loss of sediments of coastal zone results in the destruction process of coastline retreat and beach erosion. Erosion is a natural response to storm activity.

Major part of the shoreline started to retreat in 1970s according to uda et al. However other causes such as the decrease of fluvial sediment supply caused by the construction of dams see for example velegrakis et al. Other impacts also have to be taken into consideration. Submersion is only part of the cycle.

To mitigate coastal erosion the federal government spends an average of 150 million every year on beach nourishment and other shoreline erosion control measures. Beaches are able to stay intact. Beaches are in a constant state of flux accreting and eroding in response to waves currents winds storms and sea level change. Coastal cliffs to mitigate further cliff erosion which sig nificantly reduced the sand supply to the beach and caused beach erosion shimizu et al 2012.

1 in addition to beach erosion more than 80 000 acres of coastal wetlands are lost annually the equivalent of seven football fields disappearing every hour of every day. Beaches can erode both naturally and due to human impacts beach theft sand mining. The beach erosion exerts various negative impacts on the local communities environ. The beach is made up of tiny stones and sediments quartz granite feldspar hornblende and mica that are washed from our mountains by wind and weather.

Reform of agency practices is urgently needed as the risk of cumulative impacts grows. Deeper penetration of the tide into rivers and estuaries and increased saline intrusion especially during the dry season. Due to waves currents and man made structures such as storm drains the natural process of sand replenishment is hindered. This may cause troubles for water intakes and for irrigation and cause changes to the estuarine habitats.

These beaches share a common ecological danger of sand erosion. During storms sand from the visible beach submerges to form sand bars that protect the beach. Employed by coastal engineers in general and the u s. 2 the aggregate result is that the united states lost an area of wetlands larger than the state of rhode island between 1998 and 2009.

Specializes in natural beach renourishment and bluff restoration techniques which are cost effective alternatives to traditional methods dredging groins breakwaters seawalls etc. By renourishing the beach the ecosystem can be saved and therefore preserve the chain of life that exists locally. This collapse means the local ecosystem collapses with it and create destruction throughout the chain of life. 2008 and the sea level rise caused by climate change see for example fröhle et al.

Enough erosion can cause a beach to eventually collapse.
