Description

The study examines the relationship between land use change and groundwater dynamics. Specifically, the study explores what types of land use will affect groundwater level fluctuation more, using Sanpete County, Utah as a case study. Groundwater level data were collected from 49 stations in Sanpete County from the U. S. Geological Survey (USGS) website for 1990, 1995, 2000, 2005, and 2010 for the month of March. Spatial Analyst lOW (Inverse Distance Weighted) tool in ArcGIS was used to interpolate the groundwater levels in the County for each study year. Finally, the groundwater level information was overlaid with land use layers to determine their relationship. Results show that there is a lack of strong correlation between the groundwater level and water related land use from the available data. However, groundwater levels at the irrigated areas tend to fluctuate more, especially during drought periods. Future study needs to examine this relationship using groundwater data that have finer scales and better temporal resolution.
