Descriptions
A large number of channels or rills typically form on bare slopes as surface flow is generated and sediment dischargerapidly increases as the development of rills continues. In this paper, we describe an experimental study of the process of growing rills on composite soil, called "MASA-DO", using artificial rainfall. photograph of changes in plane and cross sectional patterns of rills were taken over time and sediment yield was measured. The complexity of rill patterns was expressed numerically using the co
