Application of soil acceptability forecasts

Computer models for the forecast of the acceptability of soils for earthworks in both the long-term and the short-term have been developed. A number of issues pertinent to the efficient use of the models are addressed in this report; not least, the software has been revised to ensure year 2000 compliance. In addition, a field trial has been carried out. The results indicate that predictions can generally be achieved within 2% of moisture content. The accuracy of MCV forecasts is much more dependent on the moisture sensitivity of the modelled soil. Consequently care is required in interpreting such forecasts. (A)
