Numerical Modeling of Transport of Ammonia Nitrogen in Shallow Groundwater

摘要

Through investigation and analysis of the hydrogeological conditions of the study area and using Visual MOD flow software to build 2D groundwater flow, water quality model to simulate the transport of ammonia nitrogen in groundwater. Simulation results show that pollution plume area of ammonia nitrogen will continues to expand under the action of hydrodynamic conditions along the flow direction transport and the concentration of ammonia nitrogen will be gradually reduced with the dilution of groundwater.
