Determination of ground conductivity in Bahrain by the ground-wave attenuation method

The authors discusses the measurement of equivalent ground conductivity, which plays an important role in ground-wave radio transmission. The author concludes that the humidity (moisture content) of soils is a major factor in determining the conductivity values. Measurements of conductivity as a function of moisture content show very low values for dried samples, compared with moistened ones. There is no significant diurnal or seasonal variation. The author believes this is due to the fact that Bahrain is a sand dominated country, and sand is moisture-regain sensitive
