Generating 3D soil surfaces from 2D height measurements to determine depression storage

Results showed that only one Boolean model generated surfaces with the correct mean MDS values for the smooth soil surface. Almost all models overestimated MDS, although most had correct RR values. None of the models is capable of generating surfaces with realistic storage characteristics for both experimental surfaces. However, the method is promising because it is reproducible; simulated surfaces derived from a same set of parameters are very similar in MDS. When improved, this method is potentially more accurate than the statistical two-dimensional methods based on roughness indices.
