Beach nourishment

topic of beach nourishment. The first debate is that beach nourishment is feasible and environmentally excepted method, to reduce storm and flooding risk. The second perspective is that beach Nourishment is a costly and temporary fix. Third perspective is Beach nourishment does more damage then it prevents, it merely exists to protect the homes of the wealthy, while damaging the habitats of many beach dwelling species. Below I will show three different perspectives of beach nourishment. The first

strategies in terms of the beach nourishment program. The beach nourishment process is sand being dredged from one location (in terms of palm beach from Currumbin and Tallebudgera creek) and pumped onto a different beach (palm beach). This strategy also requires dune restoration which is the process of building dunes and plating vegetation on them so they look natural. + positives Sewall Dredging Pumping - bypass - 50,000 cubic metres of sand for the replenishment of palm beach (Council of the City

amounts of sand from the beach with no natural means of replenishing it. Long Reef Beach is commendable in the amount of vegetation it has produced.

of seawalls. Seawalls may also lead to the transportation of sand away from the beach and into the sea which would result in the acceleration of beach erosion (National Resource Council, 2014). Overall, seawalls are a long-term and effective yet expensive mean to protect against natural disasters that emanate from the sea. However, they may lead to negative long-term environmental impacts such as accelerating the beach erosion process. Groynes Furthermore, another hard engineering method that is

glaciers melted about 18,000 years ago leaving behind an usual looking landform. Today, scientists know that the glaciers brought the sediment because they are all different colors, textures, and all have different layers. A big problem in Cape Cod is beach erosion. The first reason why the beaches are eroding is because of rock jetties. Rock jetties that separate beaches interrupt the natural transfer of sand by the tides and wind. The

prevent the powerful backwash of refracted waves from washing away the beach materials beneath the walls. • Base of seawalls will be undermined (weakened) and leads to their collapse. • Seawalls are costly to build and maintain as constant repairs have to be made to prevent their collapse 2. CONSTRUCTING GROYNES • Prevents the movement of beach material along the coast by longshore drift. • Allows the buildup of a beach. Beaches are a natural defense against erosion and an attraction for tourists

Relocating dredged sand onto a beach to create a buffer zone against erosion is called Beach nourishment. Moreover, the entire active profile, including the dune, must be raised by the rising sea levels to counter erosion completely. Therefore, a significant amount of sand might be required. The price of adopting this

experience during the study period. Given that the wave conditions on the Gold Coast were considerably less energetic, results suggest that Broadbeach’s beach is significantly vulnerable and is more easily eroded than other beaches reported. Time series of offshore wave conditions combined with the evolution of the beach volume also suggests that the studied beach is more exposed to high erosion rates in the presences of NE to E swell. This trend is in agreement with visual observation all along the Gold Coast

money being pumped into them. Beach renourishment, also known as beach replenishment, is the reason so many beaches still remain in good condition. The questions that need to be asked are what exactly is beach renourishment? Where has beach renourishment been used? Is it effective in preventing beach erosion and is it cost effective? Beach renourishment is described as “the process of dumping or pumping sand from elsewhere

Erosion is unfortuanately present at Cronulla beach, the local government have tried to tackle this problem with solution such as dune stabilization and rip rap walls. Rip rap walls are when larged rocks are piled in a certain angle to catch drifting sand and protect the beaches from harsher waves
