  abstract = {{T}o preserve the quality of surface water, official {F}rench regulations require farmers to keep a minimum acreage of grassland, especially bordering rivers. {T}hese agro-environmental measures do not account for the circulation of water within the catchment. {T}his paper examines whether it is possible to design with the farmers agri-environmental measures at field and catchment scale to prevent soil erosion and surface water pollution. {T}o support this participatory approach, the hydrology and erosion model {STREAM} was used for assessing the impact of a spring stormy event on surface runoff and sediment yield with various management scenarios. {T}he study was carried out in collaboration with an agricultural committee in an area of south-western {F}rance where erosive runoff has a major impact on the quality of surface water. {T}wo sites ({A} and {B}) were chosen with farmers to discuss ways of reducing total surface runoff and sediment yield at each site. {T}he {STREAM} model was used to assess surface runoff and sediment yield under current cropping pattern at each site and to evaluate management scenarios including grass strips implementation or changes in cropping patterns within the catchment. {T}he results of {STREAM} simulations were analysed jointly by farmers and researchers. {M}oreover, the farmers discussed each scenario in terms of its technical and economical feasibility. {STREAM} simulations showed that a 40 mm spring rainfall with current cropping patterns led to 3116 m(3) total water runoff and 335 metric tons of sediment yield at site {A}, and 3249 m(3) and 241 metric tons at site {B}. {G}rass strips implementation could reduce runoff for about 40% and sediment yield for about 50% at site {A}. {A}t site {B}, grass strips could reduce runoff and sediment yield for more than 50%, but changes in cropping pattern could reduce it almost totally. {T}he simulations led to three main results: (i) grass strips along rivers and ditches prevented soil sediments from entering the surface water but did not reduce soil losses, (ii) crop redistribution within the catchment was as efficient as planting grass strips, and (iii) efficient management of erosive runoff required coordination between all the farmers using the same watershed. {T}his study shown that {STREAM} model was a useful support for farmers' discussions about how to manage runoff and sediment yield in their fields.},
