A Brief Explanation on Well Water Quality Groundwater Flow Systems.
The initial ESTCP study used some terms interchangeably: injection, infiltration, and recharge. For clarity with the initial study language, we maintain that terminology in this paper to refer to the return of treated groundwater to the subsurface. The distribution of heads (one of the state variables), the source/sink data and, the candidate decision variables used or generated from the MODFLOW-96 simulation provide input to MT3DMS to solve the partial differential equation describing the fate and transport of contaminant species k in 3-D, transient groundwater flow systems.
A groundwater-flow system may consist of one or more aquifers of different types. The areal extent of groundwater-flow systems varies from a few square miles or less to tens of thousands of square miles. The length of groundwater-flow paths ranges from a few feet to tens, and sometimes hundreds, of miles. A deep groundwater-flow system with long flow paths between areas of recharge and discharge may be overlain by, and in hydraulic connection with, several shallow, more local, flow systems.
The model was calibrated with data from 2002 to 2003, with monthly stress periods. A regional groundwater flow model was also constructed for the Cretaceous aquifer system in Ordos Basin (Hou and Zhang, 2008). The model consisted of 3 layers, 330 rows and 160 columns with a uniform grid size of 2 km by 2 km. The model was calibrated under the steady state and used for analyzing groundwater flow patterns and assessing groundwater resources. And, in addition, a 3D transient groundwater flow mode1 was established for the Beijing P1ain in order to analyze groundwater flow systems.
Information from a series of investigations was compiled to conceptualize and quantify hydrologic components of the groundwater flow system within the DVRFS model domain and to provide hydraulic-property and head-observation data used in the calibration of the transient-flow model. These studies reevaluated natural groundwater discharge occurring through evapotranspiration (ET) and spring flow; the history of groundwater pumping from 1913 through 1998; groundwater recharge simulated as net infiltration; model boundary inflows and outflows based on regional hydraulic gradients and water budgets of surrounding areas; hydraulic conductivity and its relation to depth; and water levels appropriate for regional simulation of prepumped and pumped conditions within the DVRFS model domain.
