Abstract

In this study, a model was developed to describe the relationship between precipitation, surface runoff, and shallow groundwater table in a watershed that is subjected to groundwater extraction and urbanization. Regression analysis of fourteen years (1976-1989) of time series data for precipitation, stream discharge, ground water elevation, and groundwater extraction yielded good correlation between these parameters.

Analysis of the data associated with groundwater recharge and discharge events that occurred in the watershed from 1976 to 1989 yielded a high correlation between the above cited parameters. Regression analysis utilized to predict monthly variations in groundwater elevations showed a fair correlation between precipitation, stream discharge, shallow groundwater elevation, and groundwater extraction.

The Toms River watershed was utilized because it represented a hydrogeologic framework that suited this study. It is overlain by a surficial aquifer which has been exploited heavily for water supply. Also, the region has experienced substantial urbanization during the period of study.
