Two Main Reasons Beach Erosion Plagues Our Sandy Shores

Welcome back friends! Professor Loam here, rearing and ready to go!
Today we’re going to take a look at beach erosion. We love our beaches. The sun, the water, the sand, the wildlife, we love it all! But, beach erosion has become a household name around the world as it continues as a growing problem. Whether the shore is sheltered or exposed, currents, waves, and sea level change play a major role in the causes of this erosion type.
One solution is "beach restoration (beach nourishment)". However, this is not only a temporary solution, but it is also a controversial subject. Sand must be trucked in from other sources and filtered for sediment. This sand, too, will eventually make its way into the air or the water, bringing it back to its eroded state.
And from where is the restorative sand coming? This harvesting could very well have a negative impact. Aquatic life can lose habitat. Currents can change.
Ultimately, and worst of all, erosion could take effect. So really, one problem is getting solved while another is being created.
Another popular, but troublesome, solution is to build seawalls, revetments, and jetties along the shoreline. Why? Dr. Ken Ruben , assistant professor of Geology and Geophysics at the University of Hawaii, says "[t]hese have a negative effect on beaches because once sea water reaches them, it bounces off them with more energy than a wave washing back off a normal sand beach."
So what is a good solution? Nothing beats beach erosion like natural vegetation. Natural fibers, like coir, can help propagate the growth and provide stability to root systems. If a seawall must be built, the fabric underlay should be a geotextile.
