Probably Total redesign
Nope. All that can be done with those two is to optimize operation to take advantage of sediment spikes...

Are they planning on retrofitting the Caenarvon and Davis diversions to allow sediment or is that just not possible without completeley redesigning them and too high of a cost?

3. the major problem is subsidence. that the flooding that had always churned and deposited silt is gone and now marsh is compacting.
The problem with no solution. Everything else is just putting a band-aid over a bullet wound

A valid point...and there really isn't much agreement out there concerning how much a wetland actually reduces storm surge. Ridges and barrier islands play a bigger role IMO. Also, no matter how much land we create with diversions, dredging, etc, it still won't reduce the need to continually improve structural flood protection.

Like I said before in here, i would love to see a small dredge pump sediment directly into the caernarvon diversion water flow.
Doesn't have to be a big dredge, just something. Hell, they could even use a 12" Toyo pump from a barge sitting several hundred feet up stream.
I am all about getting fresh sediment into the system to do something vs just leaving the status quo.

Sounds good in theory, but the out fall channel is not designed to convey the augmented sediment load...
You would just fill in the outfall channel with sand and coarse silt...
The channel has to be designed for the expected sediment load...

I know Woody...was just quoting it so he would take note and read the plan.

Need to fix inland drainage and that wouldn't be too much of a problem. Well, not in the inland marshes and swamps at least. Cities are jsut gonna sink

Main pass has built some land closer to the river. The outside area or closer to the gulf has lost some land though.

I meant in terms of the ones sated in master plan, as in sediment diversions require new structures with different geometries than the current ones.
Posted on 3/28/13 at 4:35 pm to man in the stadium
Ah. Yes. The designs for the sediment diversion Structures, depth, width etc will be completly different as well as location and operations.

Again, how this distributary differ from a proposed diversion?
Will you show me land restoration attributable to Main Pass, this open diversion, over that progression you speak of?

Go look at the wax lake structure.
Deege, I appreciate you asking questions because you seem genuinely interested in hearing all sides. But let me ask you a question...
How will simply dredging address the problem?
Another...
Do you think speckled trout are naturally supposed to be in areas like lake lery? If not, why are they there? And I will absolutely prove you or captain Ricks or anyone who dares to say they are not...
Another...
Why are those stumps in the pond behind Reggio Marina? Where did the trees go and why?
Simply put, do you think that area is naturally more fresh or more salt marsh? By naturally, I mean, how did nature intend it? And if you think fresh, which is correct, why is it salt now, and what do YOU think is the best thing to? Keep it salt so trout can stay in close? Or transform it back to a more fresh environment/brackish water?

And deege, your Queston was answered on a previous page with advice to google cubits gap. Did you?

Sure thing. Gotta feed my kids right now. Check back later and i will try to answer any questions you may have

Main pass is a distributary in the cubits gap sub delta. It is in the detoriation phase of the sub delta progression. Google sub delta life span.
They build for a century or so and then degrade. It is cyclical. In the early 1800's, that was all open water, till a fisherman named cubit cut a hole in the natural levee...
Looking at google earth images from 1998 is not going to do you any good in coming up with arguements/observations
Hey Fish,
How does this answer the question of How the Main Pass open diversion differs from a proposed diversion?
You guys are slippery
