Experimental Verification of a Model to Predict Soil Moisture and Temperature Profiles1

A model was used to calculate water and temperature profiles over 30 d for a bare soil profile, using the hydraulic characteristics of the soil and standard meteorological data as input. The model was also used to determine the spatial variability of the calculated values, using the concept of similar media. The calculated profiles were compared to actual measurements, made periodically over the same period of time. The predicted water content values for different soil layers were within 1 standard deviation of the average measured values. The predicted temperature profiles were within 1° C of the measured values. The estimate of the spatial variability of the calculated values of water content was comparable to the variance of the measured values. Hence, it is concluded that the model was adequate to its purpose, under the conditions of the verification made.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
