A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
[The moisture content of the soil will affect the rate of infiltration; therefore, twoinfiltration tests are usually performed (if soil is dry). The first inch of water wets thesoil, and the second inch gives a better estimate of the infiltration rate of the soil.irm Soil With the 6-inch diameter ring in place, use your finger to gently firm the soil surface only around the inside edges of the ring to prevent extra seepage. Minimize disturbance to therest of the soil surface inside the ring.
