A maximum roughness coefficient of 3 was estimated for wheat, while alfalfa was assigned a maximum roughness coefficient value of 12. The following equation can be used to estimate the roughness coefficient for plants on cropland areas: (2 19) where fstm is the maximum value of the roughness coefficient for selected plants on cropland areas. 19. 19 was derived from limited experimental data. Thus, calculated roughness coefficient values should be considered as best estimates. If roughness coefficients are required for other plants on cropland areas, data for the crop reported above that is most like the material under consideration should be used.

The trends presented for the moldboard plough and planter operations are also characteristic of the other experimental treatments. In general, hydraulic roughness coefficients can be seen to decrease with greater Reynolds number. 5 Darcy-Weisbach roughness coefficients vs. Reynolds number for selected tillage operations. The moldboard plough and planter treatments produced the largest and smallest random roughness values, respectively. The largest hydraulic roughness coefficients usually occurred on those plots with the greatest random roughness.

The support frame was of variable height and was levelled in the horizontal plane. The rectangular frame was supported by four 250 mm steel stakes which were securely anchored into the soil to provide a horizontal reference. The upper left corner of each plot border as viewed from the bottom of the plots was used as a vertical bench mark, creating a threedimensional referencing system. 4 mm. When lowered onto the soil surface, the top of the pins formed a nearly continuous line which was traced onto a strip of paper located behind the pins.
