Application of an analytic element model for multi-aquifer flow in the Atlantic coastal plain, USA

Publisher Summary This chapter demonstrates the application of a new analytic element program for multi-aquifer flow to a shallow coastal plain aquifer system in Greene County, North Carolina, USA. The field site is under investigation to determine the impact of land spraying of liquid hog waste on subsurface and surface water quality. Excess nitrogen as nitrate is being measured underneath the field with a network of monitoring wells, and in the streams by taking discrete samples. Field-scale observations are being used to build watershed-scale models. The purpose of the simplified multi-layer modeling study is to test the hypothesis that simulations based on two homogeneous layers are adequate for understanding the overall water balance, and will form the basis for future estimates of nitrogen-nitrate loadings to streams in this watershed. Preliminary results are presented in the chapter.
