Abstract: The systems and methods described herein allow for intercepting submarine groundwater discharge to be used as a supply source for desalination processes. In one practice a dye-dilution seepage meter is employed as a device for locating water sources. These meters can be placed in estuaries and other locations that may be candidate locations to test for flows of groundwater. In areas of suspected SGD, the meters can be deployed to quantify the potential yield and quality (e.g. salt content) of the resource. Regarding the water quality, it is important to note that even brackish water sources can greatly reduce the energy needed to achieve potable water by desalination.

Abstract: Automated seepage meters that can detect and quantify groundwater outflow and seawater infiltration. In addition to its capabilities in saltwater-influenced systems, the automated seepage meter can detect and quantify groundwater outflow and surface water infiltration in freshwater systems (e.g., aquatic, riverine, lacustrine environments). Based on a dye-dilution technique, this instrument provides high resolution time series data for submarine groundwater discharge to the coastal zone. The dye dilution method may employ two repeatable steps: the timed injection of a water-soluble dye into a dye mixing chamber mounted in series with a seepage or collection chamber and the subsequent timed measurements of the absorbance of the dyed solution.
