Field validation of a computer model for forecasting mean weekly in situ moisture condition value

This paper describes the instrumentation used and the results obtained during a full-scale field exercise employed to validate a model for forecasting soil acceptability for earthworking. The exercise involved a 56 week long trial taking weekly measurements of in situ moisture content with depth across a natural soil deposit. A soil moisture capacitance probe was used to measure the moisture content at weekly intervals. Readings were taken at 2cm intervals up to a depth of 1.7m through a series of points in the deposit. An extensive array of data was recovered and the analysis performed on the data was used to assess the accuracy of the model. Access to all data is provided with this paper. © 2002 ejge.
