“…Para isso, o programa WinTDR 6.0 (Utah State University, UT, EUA) analisou a impedância causada pelo meio estudado, utilizando um testador de cabos da Tektronix modelo 1502 C (Figura 1), e por diferença estimou a condutividade elétrica aparente pela eq. (3) (GIESE & TIEMANN, 1975): …”

“…Dalton et al (1984) were the first to show how the attenuation of the TDR trace can be used to calculate a a . Following the thin-sample approach by Giese & Tiemann (1975), a a can be described by:…”

“…where Z L is the steady-state impedance (in Q,), fy is a temperature correction coefficient, and K p is the cell constant of the TDR probe (Giese & Tiemann, 1975;Topp et al, 1988;Nadler et al, 1991). The term K p is a calibration constant that can be determined by immersing the probe in solutions with known conductivity.…”
