For the purpose of the global water sector, “human influences” is defined as human interference directly with the hydrological fluxes of the water cycle for the purposes of any one or several of: water management (e.g. dams/reservoirs), irrigation, domestic water use, manufacturing and livestock production. I.e. human land use alone does not represent a human influence. Therefore, models that do not include any human influences (in the hydrological fluxes) at all, are to be referred to as nosoc, even if human land use is represented.
