dc.description.abstractA study of the groundwater flow system in the High Plains aquifer in northwest Kansas and small portions of eastern Colorado and southern Nebraska is ongoing as part of a Ph.D. dissertation research program. The research has compiled data from various sources into a consistent GIS geodatabase, collected detailed data in two study areas, performed statistical analyses to define key variables controlling water levels and water level declines, and developed a groundwater flow model for the area. Historical water use estimates have been made based on observed water use, well permits, and precipitation. The key variable for explaining nonpumping water levels is ground surface elevation. The statistically significant variables for explaining water level declines are ground surface elevation, water use, recharge, and saturated thickness. From theoretical calculations and observed data it was determined that pumping rates will start to decline when the saturated thickness becomes less than 40 to 70 feet depending on the hydraulic conductivity at a given well location.
