I simply love learning about beachy things! Just a few weeks ago, I came across a new-to-me shoreline term: riprap! Riprap, riprap. Isn’t that a fun word to say? Somehow it makes me think of the nick-nack-paddy-wack song.
~So sorry for the Sunday morning earworm! Really, I am!
“What exactly is riprap?” you ask. Also known as rubble, shot rock, rock armour and often spelled rip rap or rip-rap, it’s the permanent cover of rocky material (frequently granite or limestone) used to defend shorelines and shoreline structures against erosion. On the Texas Gulf Coast you can find riprap protecting seawalls, jetties, and bridge supports. It’s designed so that the rocks absorb, deflect, and/or dissipate the impact energy of waves (think tropical storms and hurricanes). The spaces between the stones are useful in trapping and slowing the flow of water, thereby reducing its ability to wash away coastal soil and structures. Alternative rock at its best!
