Three-Dimensional Coupled Fluid, Energy,

Of
GROUNDWATER
RESERVOIR
BENEATH
Long
Island
,
NewYork

Nassau
and
Suffolk
Counties
with close to 3 million people are completely dependent on groundwater for all
of their freshwater needs. As a result the hydrology of
Long
Island
has been extensively studied.
Long Island
is completely surrounded by salt water.
New York
City
derives its water from upstate, but the supply is just adequate to provide the
needs of the city. Thus the only source of fresh water on
Long Island
now or in the future is precipitation that becomes part of the groundwater
system. Luckily an adequate supply of high quality freshwater is available if
Long Island
properly manages its water.

| CFEST
3D finite element model was one of the pioneering efforts for modeling entire
Long
Island,
New
York
groundwater reservoir. CFEST model provided efficient means for mathematical
representation of complex layering system. Following figures are illustrative
sample of CFEST efforts for real world sites in their physical shapes and size.
