Storm Watch over USA with Stream Flood Status

Below you should see interactive map with active hurricane tracking over USA (Atlantic and Pacific). Also Weather Radar with current precipitation, next several days flooding outlook areas. Different color square markers indicate major river flood status with links to USGS site showing up-to-date water level and projected flooding. Purple squares - major flooding on-going.

How to convert conductivity to resistivity?

Electrical resistivity (ER) is reciprocal to conductivity (EC) and results can be easily recalculated using formula EC=1/ER or vice versa ER=1/EC. Electrical resistivity is more convenient to use on non-saline soils, where conductivity can be mSm/m, while resitivity measures in 102-103 Ohm m range. 1000 Ohm m equals 1 mSm/m. You can find more conversions to ppm, TDS, grains of salt in this flyer.

2D Dipole-Dipole Electrical Tomography with LandMapper

Manual measuring of electrical resistivity 2D cross-section is possible with LandMapper with supplied (optional) or made by user cable set.

There are two modifications of 2D cable set offered and tested by Landviser, LLC:

  1. Mobile shallow (~2 m depth) set consisted of two T-style probes (AB and MN dipoles) similar to mapping probes. The dipoles are set at 1 m size with possible separation between dipoles (wire length) no more than 5 meters (n=5).
  2. Stationary set (~ 14 m depth) where electrodes are hammered on the soil surface along the straight line at one meter distance. Electrodes are simple metal spikes/nails and is sourced locally (are NOT provided by Landviser, LLC). We supply wires with banana-plug connections to LandMapper terminals on one end and alligator clips on the other end to connect with electrodes.

Principle of measurements with both sets is the same for both cable sets and is illustrated by figure below. You can also watch instructional videos on our YouTube Channel - LandviserLLC
