Abstract:

Groundwater numerical simulation requires mass monitoring data as basic support. The input of data requires much time and energy, which may cause fault and could not predict groundwater quality immediately. Using VB language, based on calibrated and validated numerical model of groundwater flow and solute transport of Lower Liaohe River Plain, re-compiled MF2K and MT3DMS as calculation kernel programs, Microsoft SQL Server 2000 as database, the interface of real time groundwater monitoring system is established, integration of Lower Liaohe River Plain groundwater quality real-time forecast model is established, and the operation system is developed, achieving the function of real time groundwater quality prediction in Lower Liaohe River Plain. The system combines real-time monitoring technology with the groundwater numerical simulation technology. It has advantages of simple operation, strong timeliness and small error probability. The system can collect real time data of groundwater level and quality, and predict future groundwater level and groundwater solute concentration immediately. Meanwhile, update interface is pre-set to improve prediction accuracy according to accumulated groundwater monitoring data and calculated data.
