Look at a tide table - the moon cannot read and hasn't a clue when to suck it in or spit it out!


Haha, maybe it’s learnt to read ... t’internet says springs occur a couple of days after every full or new moon.
The closer the moon to earth (close moons are so called super moons) the greater the tidal range of the spring.
If there are two full moons in a calendar month the second one is called a blue moon.
Today it’s a full super moon so in a couple of days we should get a large tidal range. And it’s a blue moon as it’s the second full moon in January.
I’m sure a lot of you already knew that but I didn’t.

I thought this site explained it well (its probably aimed at children )

I’m not sure this one is a blood moon.
I’ll go with blue super moon though.

I found this:

What is a lunar tetrad? The word tetrad just means four things in a group. In astronomy, the word is used to describe four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months (six full moons).
Nowadays, each of these four-in-a-row totally eclipsed moons has come to be called a Blood Moon.

From http://earthsky.org/human-world/what-is-a-blood-moon-lunar-eclipses-2014-2015#next

The last one was in 2014/15 and the next one isn’t until 2032 according to NASA.

John - whilst idly fiddling around on this site, click on Handy Information and then Tides and you then have even more links - choose Shorebase and then click bottom right (you still with me ? ) for the new feature and fill in the no of days you want and lo and behold you will have what you want, and perhaps more!!

Moon phases , low tides in different places throughout the Broads, plus sunrise/sunset  in GMT (note this stays in GMT throughout the year so add your hour in BST ) - all you will need!! Except you are above Potter so its all dependant on many other things as well. Don't forget that up there it can be at least a couple of days before you notice what is happening at Yarmouth - blow up the bridge and it might react more quickly

Broadland tides are also influenced  by many other things including rainfall, but chiefly pressure - low pressure they come up, and high pushes it down! Clever stuff this!

And then there is the wind - a few days of strong NW winds down the N Sea pushes tide level ups in the whole of the S North Sea, and of course vice versa - for realtime predictions of whats happening out at sea see here

and in Broadland here

Now learn all that and you could become a good  'ol Norfolk boy but not yet, 'cos its all a bit of a guess!!!!

Going back to sluicing the silt out using a boat's engine, I would actually point the bow into the river, mooring the boat right forward and against the side of the dyke. I would then open up and the wash should sluice round the side and wash the mud out. I would help matters my using a 'chrome', big rake with long prongs, to break up the mud. Do it on the ebb so you don't silt up the bridge!

I did try that but the silt didn’t leave.
Possibly I didn’t use enough power. It’s only a 10hp outboard. I didn’t have it flat out.
To be honest I’m really enjoying my saucepan dydling and I certainly need the exercise. I think I need a new saucepan though, the handle’s starting to come away. I went to a farm store at North Walsham yesterday and got a long stout pole but they had no dydle or slurry scoop type of thing.

I missed this earlier. Sorry.
That’s really useful thank you.
I’m trying to learn!

I’m back tracking .... the BBC are calling it a super blue blood moon.

 

Super blue blood moon: Get ready for a rare celestial showhttp://www.bbc.co.uk/news/science-environment-42879001

 

I think strictly speaking it isn’t a blood moon for us because the lunar eclipse isn’t visible to us (not that I’m making excuses you understand )
