My question is very simple: what is the relation between both of groyne and sluice gate with the free surface topic.I can't help thinking of this thread title as the possible name for a firm of lawyers. (Along with 'Gray and Balding' and 'Sue Grabbit and Run')
As you want us to be sensible, perhaps you could give some context to this and one or two references. I think you may find that groyne specialists are rare on PF.My question is very simple: what is the relation between both of groyne and sluice gate with the free surface topic.
How can someone relate between both the flow under a sluice gate and flow past a groyne at the seaside with the free surface topic?
I was trying to visualise a system which would give variable control to the effect of 'longshore drift' on the sand on holiday beaches. I imagine sitting on the beach and watching a version of this hybrid system, wondering how it works.since sluice gates ..... not typically used on sea sides and
groynes .... used on seasides ( coastlines)
are two very different things with different uses.
