Water Table Fluctuations: The Correlation Between Distance and Groundwater Depth

Understanding the subsurface water depth fluctuations is highly required for any further groundwater studies. In this project, the historical water level of the groundwater was studied for Cache Valley, Utah. Data of wells were called from USGS using Python, through the web service ‘NWIS’ function. Only the six wells that have enough observations were selected and then located spatially on a map. The data were plotted and statistically analyzed using different tools. Also, the data of some wells showed an abrupt change in the threshold conditions of the time series after 1987. The water table depth correlation of every two wells was visually related to the distance between the wells as they fitted the exponential correlation curve more than the linear one. Quantitatively, the Pearson test proved that the correlation between wells is correlated to the distance between them.
