The Versatile Soil Moisture Budget (VB2000) is a model that was developed to describe soil water movement in one dimension through the use of meteorlogical and soil/crop properties. It was used in a 2-year study at the Stavely Range Station located 100 km south of Calgary ( 50° N; 114° W).,The soil water status of small grassland watersheds under 3 grazing intensities and 4 topographic positions (upper, middle and lower slope positions and 5 m from collector drains). Grazing treatments were defined as: ungrazed (control), heavy grazing (2.4 AUM ha�¹), and very heavy grazing (4.8 AUM ha�¹). Soil water measurements were taken every 2 weeks in 1998 and 1999, with daily air temperature and precipitation being measured on site from mid-April to mid-November.
