Abstract

A study was undertaken into the environmental and economic impacts of different soil management strategies, spontaneous grass cover with and without gully control (SC/SCGC) or conventional tillage with and without gully control (T/TGC), based on the experimental results obtained in an olive crop microcatchment in the province of Cordoba, Spain. The AA. calibrated a AnnAGNPS model at event and monthly scales providing suitable adjustments of runoff, peak flow and sediment loads. Ephemeral gullies were also identified using aerial orthophotography and field work. The module of the AnnAGNPS model for simulating ephemeral gully generation and the tillage operations based on a bibliographical review were used to compare different scenarios and to perform a 10 year-analysis. The results showed significant differences in sediment losses and gully contribution, and no obvious incentives to apply soil protection measures due to higher costs
