Technical Memorandum Review of the Proposed Rosemont Ranch Mine Hydrogeologic Analysis and Groundwater Model

Document ID: 012179
2010

The MODFLOW-SURFACT computer input tiles and Groundwater Vistas (GWVistas) files were also made available for review. There were three file sets available, including SteadyState, Trans_DRN, and Trans LAK. The first is the final steady state model run, the second is the transient simulation during pit development, and the third is a simulation of pit lake development. Output files were not included, except that the file SteadyState.hds, provided as initial conditions for the Trans_DRN model runs, was the result of the steady state simulation. The files were used to examine details of the modeling not described within the reports. As described within the review, the files were converted to MODFLOW and simulations run to develop the water balances discussed herein.
