Hurricane Seasons, Erosion, Rising Seas, Sinking Land Mass

There is the Houston Galveston subsidence district which highly regulates water well drilling in that area. There is a permit fee to drill and a per thousand gallon fee that they charge. It is different for residential, commercial and industrial. If memory serves me right. The disincentive fee for industrial is greater than the cost of deslanization. They want to encourage the use of Gulf water for industrial use.

Since we have been using GPS for surveying. We have found that the land in rice growing areas can subside as much as 12 to 18 inches during rice flooding season. It rebounds when they stop pumping. The area from the coteau ridge to the east all the way to New Orleans is, geologically speaking, a new born. Not even in diapers. It alluvial deposits with high voids ratio filled with water. The general rule of thumb is the subsidence is 1.5 cm per year. If that is not replaced with spring flood deposits then we are behind.

Our Subsidence situation along with poor soil characteristics is manifested in the poor condition of our roads.

Long suspected the rice growing area numbers.

Did not expect the bounce back numbers due to so much clay and runoff. Thats encouraging.

Yep, Louisiana roads are buit on jello.

They are pumping water from a sand aquifer not the clay/silt overburden. When they stop pumping the aquifer recharges lifting the overburden.

Made my day.

I still think Louisiana should employ some "Cajun Nova Scotia Know How" with land reclamation.
