types of rip current

[gapsta]

hi guys,
id like to know what 3 types of rip current occur in a surf zone.
any information or links would be more than apreciated
as i need to know for a study im doing.
i can see what a rip looks like but ive never known a name for it
'john,betty,frank' would be a good place to start for all i know

There's a starter...

Never knew they had different names tho, only that they form in different condtions eg round a point or cliff face when the swells hitting at an angle. round sandbanks and lagoons.. etc.

cheers guys,
yeah i had fixed and flash yet the only other i can think of is longshore drift.

Longshore drift (or L.S.D. as we liked to refer to it in geography lessons at school ) is a type of coastal erosion not a type of rip. It promotes the formation of sand spits such as Blakeney Point in Norfolk.
I know at least locally here most surfers mistakenly call the tidal current, which flows accross shore both ways, a rip.

oh my god we did the exact same thing! LSD and blakeney point stuff and spits and salt marshes! wow! were currently doing a decision making exam about maldives and global warming. funfunfun!

"Cross shore rip" I think is the phrase

[PapaW]

Was going to say lsd isn't a type of rip!

don't forget the effects of tidal flow can create rips... especially around rock points.

[gapsta]

yeah cool i have longshore drift in another section of my paper here it is:
Longshore drift is a type of rip usually tide generated which moves up or down the beach parallel to shore in the direction of tidal flow. Prevailing winds can also increase longshore drift as well as swell hitting the shore diagonally.
Long shore drift is stronger on rougher days.

i think one of them is called john
