| Abstract: | The ammonia-nitrogen in shallow groundwater of coastal area of Tangshan Fengnan exceeds the content limit at varying degrees. To analyze the the migration features of ammonia-nitrogen in the groundwater, a two-dimensional groundwater flow and quality model has been established on the basis of investigation and analysis of hydeogeological conditions in this region. Ammonia-nitrogen in the first aquifer groundwater migrates slowly and is difficult to diffuse during the migration process for the low exploitation, the small hydraulic gradient, the relatively fine aquier rock particles and poor permeability of the aquifer |
