Juniper Publishers- Open Access Journal of Environmental Sciences & Natural Resources Seawater Upconing under a Pumping Horizontal Well in a Confined Coastal Aquifer Authored by Dongmin Sun Abstract We have investigated the seawater Upconing due to a finite-length pumping horizontal well and derived an analytical solution of sharp fresh/sea interface based on the solution of Dagan & Bear [ 1 ]. The results are compared with those of vertical wells. The Upconing profile exhibits three stages with time: an early slow increase stage, an intermediate rapid increase stage, and a late steady state stage. The sensitivity of the interface rise to the well length, the well location, the aquifer anisotropy, and the observation point location is analyzed. We have also investigated the critical condition of seawater Upconing based on Muskat [ 2 ] idea by relating fresh/sea water interface Upconing to drawdown. The critical condition which includes the critical rise and t...
