    Finding ditch depth with four-electrode resistivity measurement

    He's going to archaeological research the castle, which will be preceded by geophysical measurements. The challenge is also localization said ditch. According to available information, it is almost certain that trench was carved into the rock, its depth could be around 6 meters and width of 6-8...

    Finding ditch depth with four-electrode resistivity measurement

    Please, its depth is 6 meters and width 6-8 meters. How far AB hypothetically you chose if you think that the resistance measurements would allow to determine the presence of a ditch. Formula is ρz = k * AU / I. What am I substitute. Please, help me...

    Finding ditch depth with four-electrode resistivity measurement

    Hello, Could you help me with the homework, please...For the conventional resistance measurement used four electrodes: two current (A, B) into the country "deserts" and the current I between two measuring (M, N) is then measured voltage AU, resistivity, which is the goal of our measurement is...
