How to quantify the processes through the change of surface roughness will has important practical significance for understanding of the relationship between microtopography and erosion, and weighing tillage practice options.

However, the optimal critical slope for appropriate tillage remains unidentified.

So, the aim of this paper is to characterize the change of surface roughness of microtopographic sloping land in the process of sheet erosion, which is affected by factors of rainfall, slope and tillage.

This work approached only one factor i.e. slope gradient and we anticipate more factors and indices will be covered in our future research.

Move 3:

Presenting the present work

Step 1:

Announcing present research descriptively

The purpose of this effort is to shed light into the microroughness and hydrological responses during the evolution of erosion, so as to generate soil erosion models on the microtopographic scale and examine the critical slope value,
