Figure 3: Estimated annual volume (m3) of sediment eroded for the period 1990–2012 (red bars), as well as the obtained Modified Fournier index (MFI: blue line) and the Bagnouls-Gaussen index (BGI x-1: orange line).
From: Gully evolution and geomorphic adjustments of badlands to reforestation

Sediment yield data show a clear change in the trend after 2007, but are not correlated with high IF values.
