Resource Abstract:
- description: The dataset consists of selected water conductivity profiles in text file format from well Sec34-MW-02-FS, which
were used to evaluate the rate of movement of the saltwater interface. The inland extent of saltwater at the base of the Biscayne
aquifer in the Model Land area of Miami-Dade County, Florida, was mapped in 2011. Since that time, the saltwater interface
has continued to move inland. The interface is near several active well fields; therefore, an updated approximation of the
inland extent of saltwater and an improved understanding of the rate of movement of the saltwater interface are necessary.
A geographic information system was used to create a map using the data collected by the organizations that monitor water
salinity in this area. A rate of saltwater interface movement of 140 meters per year was estimated by dividing the distance
between two monitoring wells (TPGW-7L and Sec34-MW-02-FS) by the travel time. The travel time was determined by estimating
the dates of arrival of the saltwater interface at the wells and computing the difference. This estimate assumes that the
interface is traveling east to west between the two monitoring wells. Although monitoring is spatially limited in this area
and some of the wells are not ideally designed for salinity monitoring, the monitoring network in this area is improving in
quality and spatial distribution. The approximation of the inland extent of the saltwater interface and the estimated rate
of movement of the interface are dependent on existing data. Improved estimations could be obtained by installing uniformly-designed
monitoring wells in systematic transects extending landward of the advancing saltwater interface.; abstract: The dataset consists
