  • Estimating soil conductivity for GPR surveys

    The results of a ground penetrating radar survey depends on many factors. In order to get useful data and good penetration, one of the conditions is that the conductivity of the ground is not too high. The conductivity of the material together with the operating frequency and the dielectric constant allow us to calculate the loss factor that is used to roughly estimate the theoretical ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • Park City, Utah Arsenic removal from ground water

    Background Park City Utah Water, which serves a population of 6,500, has five water sources. Spiro Tunnel and Spiro Portal are two that were in need of Iron and Manganese removal as well as above limits for Arsenic. Filtronics was engaged by the engineering firm of Eckhoff, Watson and Preator (EWP), Salt Lake City, to perform pilot tests for the Park City Municipal Corporation. The ...

  • Expert assessment: Sea-level rise could exceed one meter in this century

    Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientific publishers on that topic has revealed. The 90 experts participating in the survey anticipate a median sea-level rise of 200-300 centimeters by the year 2300 for a scenario with unmitigated emissions. In contrast, for a scenario ...

  • Mapping sedimentation features in an alluvial valley

    Sediments of the Rhone river are characterized by strong heterogeneity between clay, sand and gravel units. To map these units, we employed an electromagnetic instrument (DualEM421). This instrument das the advantage that no contact to the ground is required and it can be carried on foot. With the interpreted data it was possible to map different geologic units to a depth of up to 4.5m. ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...
