The use of soil corrosion probes to determine actual corrosion rates can assist in determining the effectiveness of cathodic protection (CP) in high resistivity soils. This technique is useful in situations where poor reference cell soil contact in very dry soils results in erroneous CP potential measurements. This paper presents the results of an on-going study evaluating the use of soil corrosion probes as an alternative monitoring tool to determine the effectiveness of CP in the dry desert soils of Saudi Arabia.
