What is a groin in geology?
Groins are shore perpendicular structures, used to maintain updrift beaches or to restrict longshore sediment transport. By design, these structures are meant to capture sand transported by the longshore current; this depletes the sand supply to the beach area immediately down-drift of the structure.
Is groin in the dictionary?
Anatomy. the fold or hollow on either side of the front of the body where the thigh joins the abdomen.
What are jetties and groins?
Typically, jetties are concrete or rock structures built at inlets and channels in order to maintain channels for shipping and navigation. A groin is built perpendicular to the coast and works similar to the way a jetty works.
What are groins and groin fields?
Groins are shore-perpendicular coastal engineering structures. Groins are usually placed in groin “fields” (multiple groins) and are meant to inhibit the alongshore movement of sand and “catch” sand.
What area is the groin?
The groin is the fold where the bottom of the abdomen meets the inner thighs. The inguinal ligament connects the oblique muscles in the abdomen to the pelvis. The oblique muscles wrap the sides of the body, from the ribs to the pelvis.
Why do we need groins?
Groins are built to stabilize a stretch of natural or artificially nourished beach against erosion that is due primarily to a net longshore loss of beach material. Groins function only when longshore transport occurs. Groins are narrow structures, usually straight and perpendicular to the preproject shoreline.
Can a girl pull her groin?
Most common cause of groin pain for females
A “groin strain” usually refers to torn or overstretched adductor muscles, which are located on the inside of the thigh. These types of groin injuries are usually the result of overuse or overexertion and are common among physically active people.
What is a water groin?
groin, also spelled groyne, in coastal engineering, a long, narrow structure built out into the water from a beach in order to prevent beach erosion or to trap and accumulate sand that would otherwise drift along the beach face and nearshore zone under the influence of waves approaching the beach at an angle.
How is a groin different from a breakwater?
A breakwater is designed to block waves and the surf or to reduce beach erosion, which is not dissimilar to a groin, which is also designed to prevent beach erosion. However, a groin is perpendicular to the shore and a breakwater parallel to the shore.
Do you have 2 groins?

What is the problem with groins?
The problem with groins is that they trap sand that is flowing to a neighboring beach. Thus, if a groin is growing the topographic beach updrift, it must be causing downdrift beach loss.
Why are groins bad?
The negative impact of groins on downdrift shorelines is well understood. When a groin works as intended, sand moving along the beach in the so-called downdrift direction is trapped on the updrift side of the groin, causing a sand deficit and increasing erosion rates on the downdrift side.
Where is a woman’s groin?
The groin area is where your abdomen transitions into your lower body and legs. It’s located near the hips, above your upper thighs and below your stomach. Pain or discomfort in your groin area is most commonly a result of straining, pulling, or tearing one of several groups of groin muscles or ligaments.

What is the major drawback of groins?
What is a woman’s groin called?

Do you say groin or groins?
The plural “groins” simply refers to the groin of the left leg and that of the right leg, taken together. However, when some teachers say “groin,” they are referring only to the part of the groin nearest the inner thigh.

What are the disadvantages of groins?
One of the biggest problems with groynes is that they can have an impact further along the coast by stopping longshore drift. By trapping the sediment, groynes starve towns and villages of sediment further down the coast.
Do groins cause erosion?
It is clear that on a shoreline where sand is transported laterally, groins will always cause erosion.
How do groins affect the environment?
Do groins stop beach erosion?
Groins. Groins are another example of a hard shoreline structure designed as so-called “permanent solution” to beach erosion. A groin is a shoreline structure that is perpendicular to the beach.
