Flooding FTW (MORE PICS!!)

Woah, that third last one is awesome.

It was a great day all round i say.

nothing like an impending natural disaster for some fun.


Wonder how many trollies/other random crap students put in the leith got washed out to sea to become a shipping hazard?

Did anyone else see the kyakers in the leith about lunchtime? apparently they were going hardcore untill some nazi called the cops who got stropy at them for being idiots.

I heard there was a slip at moraki & also on the kilmog, anyone of those places could of blocked the road.

Nice pics guys.

Pity no real carnage was caused, would of liked to seen a bridge washed out

[CozmoNz]

the bridge down by fisher and paykel (and south air) has been buggered at the factory side....

about 1-2meters of it missing.. and thats the bridge we use!... so looks like the long way around for us.

This morning (if your interested), Fisher and Paykel workers start at 9, Leading hands at 8, (were gonna listen to the radio still incase the leading hands see its just not worth doing anything today). We are required to bring wet weather gear... gumboots especially.

So 6 hours of pushing water around... I can handle that.

What is the Leith? is it like a storm water drainage thing?
And why does it look like there's a monster swell in the same spot in all photos?

Awesome pics, now bring out Toni Marsh for the weather

The leith stream is just that... a stream... a very small river I guess if you want to call it that.

Basically all the storm water from the northern end of the central city seem to drain into it

The Leith is usually a calm stream flowing at 2 cumecs, at 9am yesterday it was 95 cumecs

Yeah it is a storm water drain out to the harbour. There's a catchment pond up the hill a bit and a couple of other streams lead into it as well. It's usually 3m below those banks and as you can see from the photos it was coming over. Reason for the same swell is the uneven river bed, just think of a river with big boulders and the rapids that it produces.

The lost pictures!

The Leith (i think) way upstream - deep in North Dunedin or somewhere.


St Clair Esplainade - doesn't look all that impressive from this angle


But does here (i don't think the waves were at their highest in this shot!)

Found them still hiding on the camera, musta died before it finished uploading these three.

Its cause some dimwit flood engineer back in the dark ages decided to put all these weir type things in to help in flood situations, hmm i think someone should dig him up & tell him it didnt work, all it does is makes lovely waves.

I think it might have something to do with cleaning the river bed of crap or something, someone with more knowledge of river dynamics & flood engineering/civil engineering might have a better explanation

I'd imagine they are slowing the flow a bit....

[rolla_fxgt]

i think the whole idea behind them from what i understand is, that in times of high rain (not floods like yesterday) the weirs speed up the water flowing over the top of them creating a flow of water that clears the build up of rocks etc on the river bed. Also a low pressure current is created under neath the high speed flow, creating a backdraft, creating a surge as the flows interact, in floods the surge is just, much much bigger.

the whole scheme back in the day was created to speed water flow, they didnt like it back then, hence the heavily concreated sections, there were even some plans to cover it over & leave it as an underground culvert. Imagine the problems that would of caused when it flooded

faaaaark
hope nothing has happend to interfere with rally otago......
