Shallow flow of water through nonsubmerged vegetation
The shallow movement of water flowing through dense crops of wheat was studied for different crop densities and sowing patterns and ages. The common application of Manning's equation to such flows is shown to be inadequate, particularly since the flows can be described as mixed rather than turb...

| Zusammenfassung: | The shallow movement of water flowing through dense crops of wheat was studied for different crop densities and sowing patterns and ages. The common application of Manning's equation to such flows is shown to be inadequate, particularly since the flows can be described as mixed rather than turbulent. The more general discharge-depth equation has advantages for coping with the conditions, and relevant values of the parameters are provided for both (slope) super(0) super(5) and a suggested (slope) super(0) super(3) super(5) . |
