The topography, rill pattern and geometry were surveyed within a small agricultural field. The rill network and dimensions were converted to a grid-based system and used to calculate the slope gradient and contributing area for each grid cell. A strong correlation was found between the rill cross-sections and a power function of slope gradient and contributing area. The slope and area exponents were 1.28 and 0.89, respectively, for all rill points, and 1.02 and 0.87, respectively, for the rill points not lying in the depositional area. These exponents are within the range reported for field studies in a one-dimensional context.
