To reduce beach erosion during storms and hurricanes, communities are installing
large multi-compartment sandbags along the shoreline. We had the opportunity
to watch each phase of the installation.
The grand kids would have really enjoyed
watching the bulldozer, front-end loader, and large shovel do their thing.
As before, here are just a few of the many pictures.

This is the start of installing bag number two.
The trench is dug and ready for the empty bag.
Sandbag one is buried on the other end of the trench. You can see the
end of the bag under the sand.

|
Bag number two is laying in the bottom of the trench and waiting for
connection to the water and sand pumps.
|
|
The orange pump sucks water from the ocean and forces it into the bottom
of the black hopper.
The front-end loader dumps sand in the top of the hopper where it is strained
and then mixed with the sea water from the orange pump.
A second pump is in the bottom of the hopper which is used to pump the water/sand
mixture through pipes to the waiting sandbags.

The sandbags have ports in the top which are used to allow water to exit
after it deposits the sand in the sandbag.
A rod is used to determine the depth of the sand under each port. If the sand
is building too fast under a port it is closed off until other ports catch up.
The large shovel has to dig a trench out to the ocean to allow the discharged
water to get back to the sea.
You can see the shovel digging the trench for bags three and four.

Bags two and three are ready to be covered.
|
|
The shovel and the buldozer take their turn covering the bags.
|
|
Bags two and three are now covered.
They are getting ready to fill bag four.
The project must end by May 15 to allow for the turtle nesting.
