Using a hydrologic model to estimate daily soil moisture at 258 evaluation locations over a 30-year period, the spatial variability and persistence of soil moisture across Oklahoma is examined. The Soil and Water Assessment Tool (SWAT) uses readily available meteorological inputs with detailed land surface information. An autocorrelation analysis is used to evaluate the persistence of soil moisture at each evaluation location. Land surface characteristics potentially influencing the persistence of soil moisture across Oklahoma are examined, including vegetation type and soil texture and depth. Of the 3 parameters, soil depth plays a significant role in the memory of soil moisture conditions. As the soil profile depth increases, a corresponding increase in the persistence of soil moisture occurs
