Yes we are you fucking 'tard. The beach protects the aquifer underneath the city. As the beaches get eroded they no longer prevent sea water intrusion. It's BASIC FUCKING HYDROLOGY you dipshit. Read a fucking book and learn something instead of spouting off shit you have no clue about!

And here, Westwall fails hard at basic hydrology.
The water level will only rise above previous water levels if there's more pressure behind it. Sand, being water permeable, has no effect on that pressure. Water is rising higher than it used to because increased sea levels are increasing the pressure behind it. Whether the beach is big or small has no effect on that.
Sand is permeable when dry. When the beach is healthy it has a solid layer of salt water that prevents the sea water from intruding further.

A solid layer of salt water?
Do you understand that salt water is a liquid? Apparently not.
Do you understand that sea water is salt water? Apparenlty not.
Your crank theories keep getting crankier. You've proposed a solid layer of liquid sea water keeping out the sea water.
In contrast, I just have to point out that fluid in a permeable basin rises until downward pressure matches upward pressure, and that rising sea levels have increased that pressure. No magic solid walls of water required.
Silly kitty. Read the paper I provided you. It will teach you things.

That paper says nothing that backs up your "a solid wall of liquid salt water blocks the other liquid salt water" theory.
What physical process turns liquid sea water into a magical solid wall of sea water that blocks out the other sea water? You've proposed a result much like this. Needless to say, we'd like to hear about the mechanism which makes that happen.
It's not magic, and you clearly didn't read it.

I don't think the hairball understands the concept of an interface between salt water and fresh water. It is funny watching her pretend to have a clue and suggesting that she is helping you out though...she is always good for a laugh.
Why are you yelling?The present rate is unprecedented.

UNDERSTANDING THE GEOLOGIC PROCESSES OF COASTAL LAND LOSS FOR
THE RESTORATION OF NORTH AMERICA'S LARGEST RIVER DELTA-THE
MISSISSIPPI
PENLAND, Shea, University of New Orleans, New Orleans, LA 70148, [email protected] and
WILLIAMS, S. Jeffress, Coastal and Marine Geology Team - Woods Hole, U.S. Geological
Survey, 384 Woods Hole Rd, Woods Hole, MA 02543.
The Mississippi River delta is a vital natural resource to the United States. This resource is at
risk of vanishing, between 1932 and 1990 this delta lost over 680,000 acres of critical habitatswamps,
marshes, and barrier islands. Understanding the critical processes of land loss is
essential to the rescue of this national treasure. Over the last 20 years the USGS in cooperation
with the USACE and Louisiana universities have investigated processes of erosion,
submergence, and man's impacts in addition to geologic framework studies of Holocene coastal
evolution and sediment resources. This information is key to developing successful restoration
strategies and projects. Without the implementation of significant restoration programs the
federal and state natural resource trustees predict the economic impact of the coastal land loss
crisis will exceed $ 100 billion by the year 2050. The Coastal Wetland Planning, Protection, and
Restoration Act (CWPPRA) of 1990 was a start with $ 40 million per year dedicated to
restoration activities. From CWPPRA successful freshwater diversions, marsh creation, and
barrier island restoration projects were implemented. In 1998 the federal and state natural
resource trustees realized a larger restoration program was needed to reverse the magnitude of
Louisiana's land loss problem. As a result, the Coast 2050 initiative was started to implement the
largest coastal restoration program in the U.S., $ 14 billion through the Water Resources
Development Act.

A fascinating article and video by the BBC on the impact of rising sea levels and irrigation on the US coastline...
Life on a Louisiana island slowly disappearing into the sea
The US state of Louisiana is slowly disappearing into the Gulf of Mexico as its fragile wetlands are eroded by rising sea levels.
Approximately 75 square kilometres are lost each year and the US Geological Survey has warned that the entire habitat - which represents 40% of all wetlands in the US - could be destroyed within 200 years.
The loss is partly down to natural evolutionary processes, but experts say human behaviour - including dredging for canals and the draining of the wetlands for development and agriculture - has made the region more vulnerable to storm surges.

Sand is permeable when dry. When the beach is healthy it has a solid layer of salt water that prevents the sea water from intruding further. The problem Miami has is the newer freshwater wells have been drilled closer to the ocean and they have lowered the water table by up to five feet which allows the sea water to intrude to fill the void that is left. But that is basic hydrology. Something mammy here clearly doesn't understand.

BBC story about High Tides in LA is interesting, Most of the isle in LA were formed from tides and shifs in the Gulf and they just don't get it.A fascinating article and video by the BBC on the impact of rising sea levels and irrigation on the US coastline...

300 years ago LA was under water if you read some history. Same as in England....and some species are turning female too!!
13.) The marine food chain could fall apart.
14.) Within 300 years, 88% of New Orleans could be underwater.
15.) Increasing droughts will make the driest regions even drier.
Don't forget the La Polars bears are drowning.Is this because the oceans are getting warming, or the polar ice caps are melting or what?
