Information On Using Resistivity Method

Resistivity method is used in archaeological studies that are done in order to find out about the formation of the earth

. This technique has been used for many years though it has developed due to technological growth. The types of instruments used are very accurate and require minimum human operation. This means that they are automatic and do not require a person to operate them. All one needs to do is set up all the necessary equipment.

Resistivity method applies the electrical technology which in turn determines the resistance of a particular substance. In this case the substances include rocks and soil particles. Places with damp soils will have a low resistance whereas places with rocks and dry substances will offer a high electrical resistance. By using search information it is possible for an archaeologist or a surveyor to determine the land features of a particular region. It may not be a perfect method but it is one of the best.

One may wonder about the equipments used in resistivity methods. They are simple handheld tools which are easy to operate. The most common equipment is a resistivity meter that is used to determine the resistance offered by a certain substance in the surface of the earth. The good news is that some of these devices can be easily assembled at home. It means that one does not have to buy an expensive device in a store. However, one is advised to always rate the accuracy and importance of the research before making a decision on the tools to purchase.

People often make mistakes when carrying out such services and end up correcting wrong data. Wrong data will result into wrong analysis and conclusions. It is essential to use the internet as a resource for research.

Resistivity is popular among professionals in the field of survey. There are numerous methods as well as techniques that are available on the accredited websites. However, some of the sites are not official and provide either biased or wrong information. It is advisable to be careful when using them to avoid getting the wrong aspect about the research method. Other than sites one may choose to read electronic books that can be downloaded from the internet at a very low cost.

This technique may seem perfect but the truth is that it has some disadvantages. It is very hard for an individual to tell whether a particular region has damp soil or many rocks by looking at the surface. It is therefore necessary to carry out a study in order to determine the water levels of a particular region.

This method may lead to wrong findings in places where the water content has been affected by the activities of human beings. People may have resulted to wrong practices that result to desertification. This will not change the geological information of the place and by using such techniques one will collect the wrong data.

Another major disadvantage is that the technique is not applicable in areas with low mineral and water levels. This means it is not a hundred percent efficient.
