Terrace Volume

Calculate cut-and-fill quantities for one specific terrace.

This function allows you to calculate cut-and-fill quantities for one specific terrace at a time .

Once the terrace (with or without banks) is identified, a DTM grid is run across it and the cut-and-fill volumes are determined. Figures for compaction and topsoil stripping can be incorporated, and a final figure is presented. The results are presented in the Output window as usual.

The volume data is substantially the same as is given under DTM - Design/Surface Difference.

Use this function to get a preliminary idea of whether the cut-and-fill balances for a specific terrace. If the quantities do not balance, the terrace may be very quickly adjusted and the procedure used again.
