In a given harbor, what general rule often determines
where the shoals are? Explain your answer. [1 pt]

Places where there's little or no current. This allows silt and sand and mud to settle outta the water.
Places with current get scoured and the silt and sand and mud doesn't have a chance to settle to the bottom.

Cheers,

Shoals are found where the water is shallow, or alternatively, where
the bottom is high.

Right, Bart?

Shoals are usually found behind the markers.

Thanks. The shape of land would be points (promontories?). They make a lee in the currents and the slow current
lets the suspended silt, sand and mud settle out. You can see lots of points (moles?) being built along the beaches in
Florida on the east coast side. They keep all the sand from being washed away because they slow down the current
going past. They make eddies. When you sail on a river it's usually deeper on the outside of the bends. The insides
are shoaling up. This is because water slows down on the inside and it speeds up on the outside.

Cheers,
Ellen

Yeah Scot,

Usually where the dredges are working. If there are canal marker, there
are shoals.

As Bart stated, "A given Harbor." Not sure but I think Bart was
thinking of a harbor being feed by a stream or creek. The outlet or
"Delta" is where the shoals form

In a harbor you look for different surface condition, Shorter wave
lengths, no waves, ect, waves on top of shallows are usually of a
shorter wave length and higher, or you may see calm in a shallow vs
waves in other areas.

Good answer Neal. Worth a point.

But there is more to it than this.

Have you looked at multiple harbors in the same general
area and compared them? What other conclusions can
you draw?

Sometimes, in some places, the water is so shallow that the
bottom actually sticks up above the surface.

Nothing at all. Once you go black you never go back! Besides,
Negro women appreciate any real man, even if they have to settle
for a Caucasian guy. It seems most Negro men are too irresponsible
to marry, settle down, get a job and actually support their offspring.
They'd rather hang out, listen to hip hop rap crap, deal drugs, play
'bassaball' and chase 'tang.

A lake I sail on added a dam that raised the water level 3 feet. So the
easy answer to where the shoals are is: "the shoals are where the
islands used to be."

While sailing thru an area of innumerable shoals with twisty
channels between them (and current, of course), my wife once
made a remark I considered hysterically funny at the time,
but have since realized was very wise:

"Good thing it's low tide, now we can see where the shallow
spots are."

WTF Bart?

You never read Life on the Mississippi by Mark Twain?

He has the best descriptions you will ever find of how to reconize
shallows, snags, silting, deep water, ect. He describes running the
mississippi at night like a man remembers how to walk down a hall in
his house in the pitch dark. My descriptions of shallows match Samuels
descriptions to a tee. You read the surface and notice very subtile
differences of how the water is effected by things below the surface.

One problem, Joe. Mark was talking about a river, with
strong current. Bart was talking about a harbor.

they are seperate & different things. Mark Twain had some

No kidding Doug, I'd never figured that out without your help, but the
same effect can be seen in a rivers movement and a harbors tide, you
may not beleive this but water moves in both harbors and rivers, and
shallows effect the surface in very similar ways.

I think relatively few harbors have *that* much current,
even at the most constricted part of the channel. And the
current's effect over a shoal will be masked by wind.

I know of one hazard due to current in many East Coast
inlets that I don't believe Mark mentioned, and that is
current going over a shoal from the channel... ie tending to
pull your vessel onto it. In fact, several NC inlets have
this effect strongly enough (on some tides) that they have
not only pulled boats aground, but also piled up sand over them.

It certianly is possible to notice the difference in waves
over a shoal but only when the waves are relatively high
compared to the water depth. Most harbors will very rarely
develop 2' waves which is what it will take to reveal a 6'
shoal. Big wakes help, if there happens to be one crossing
the shoal in question when you happen to be looking.

Reading the waters surface is a good skill but it doesn't
take the place of a chart and it sure ain't the same as on
Ol Man River IMHO.

The only one I can remember off the top of my head is: "The
difference between the right word, and almost the right
word, is the difference between lightning and the lightning
bug." -Mark Twain

The point I was trying to make is that in harbors the wind
pushes the water around. On Long Island Sound you will
notice a distinct pattern where the west side of harbors
have the most silt. The reason being, the eastern sides are
exposed to a longer fetch and this tends to make the east
sides deeper. The cause--the prevailing westerlies.

When you say " distinct pattern" do you mean surface conditions like
shorter wave
lengths, no waves, ect, waves on top of shallows that might have a
shorter wave length of differnt pattern than normal, or you may see
calm in a shallow vs
waves in other areas?

The reason being, the eastern sides are
exposed to a longer fetch and this tends to make the east
sides deeper. The cause--the prevailing westerlies.


That makes sence, I bet the wave patterns are distinct and shorter
waves lengths.

Just wondering.
