Dunes vs Storms

Storm frequency and damage varies by year. Often dunes protect against minor storms. However, during larger storm events, some coastal damage may occur even in areas with dunes. For more information on major storms in New Jersey history, click the button below.

Coastal storms cause severe levels of damage to coastal communities. Through wind, wave, and flood damage major storms create an economic issue for coastal communities. For more information on damage from Hurricanes and Tropical Cyclones click the button below.

Coastal storms (Hurricanes or strong winter storms) can cause erosion and damage to coastal areas. For a description on different types of coastal damage caused by storms, click the button below. 

Dunes provide a barrier between coastal storms and coastal communities. Dunes protect against storm surge and high wave activity and can reduce coastal flooding. To see how effective dunes are in providing protection, watch the video below showing how beach dunes protected a coastal town from damage during Hurricane Sandy.

When looking at protection provided by dunes, size is one of the most important factors. But at what size do dunes become a protective feature? To learn more about the requirements for a dune to be considered a protective coastal feature, click the button below. 

There is no doubt that dunes provide protection against storms. But what is the exact economic benefit of these systems? While estimates may vary by different studies and surveys, a study based on Texas found that dunes prevented approximately $8,200 in damages to each property owner.

With time dunes can begin to erode and break down. When dunes wear down, it is important that they are restored. One of the main ways to improve dunes is to plant dune grass. Planting dune grass anchors dunes and helps additional sediment accumulate. To see how dune grass is planted click the button below.
