GroMoPo Metadata for Tongliao 3D model

The use of groundwater flow models1 is prevalent in the field of environmental hydrogeology to predict the fate and transport of contaminants for risk evaluation purposes. In this paper, the authors develop a groundwater flow model in Tongliao city, China by using Visual MODFLOW. The conceptual model was built by analyzing the hydrogeological data. Hydrologic parameters have been calibrated based on the available data observed from 1999 to 2002, the calibrated results show that the computed water heads fit into with perfectly the measured data, which indicate that the conceptual model and the parameters used in the model can reflect the actual physical system of the study domain. The calibrated parameters will be very useful to identify the aquifer properties and to analyze the groundwater flow dynamics, the changes of groundwater levels in the study area.
