CS616 Calibrations

This document presents laboratory setup examples that illustrate the influence of temperature on soil-specific conductivity (CT). The analysis includes methods to optimize the CT based on temperature variations, drawing from established equations by Wang and Schmugge (1980) for parameters N ≤ 0.5 and N > 0.5. Additionally, it provides detailed calculations of catchment-wide soil temperature, emphasizing a notable average error of 0.73°C and a maximum error of 2.43°C, with a standard deviation of 0.27°C. These findings contribute to enhancing accuracy in soil conductivity assessments.
