  • Tidal influences on unconfined water levels in wells.

    Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Regional modeling of wells

    The ability to represent wells in a regional three-dimensional numerical groundwater model is crucial for many modeling exercises. Such wells can either be measurement wells where groundwater levels are measured as a function of time, or wells can be pumping wells in which water is removed from the well and a drawdown cone is created in the water table surrounding the well. There are numerical ...
