Groundwater models produced from GOYDER INSTITUTE FOR WATER RESEARCH Project No. E1.11. \n\n A series of numerical groundwater models have been designed to represent generic floodplain conditions that exist along the River Murray in SA, from the border to Lock 1. The aim is to improve understanding and modelling capability of flow and salinity dynamics, to assist with management and engineering decisions. \n\nMultiple base case scenarios are considered, varying by floodplain topography, the presence or local absence of a lock, and whether the river conditions are gaining, throughflow or losing. Model variants were developed to investigate how results depended on the methods used to simulate key processes, including river level changes, floodplain inundation, groundwater evapotranspiration, and solute transport.\n\nThe MODFLOW and MT3DMS simulations were developed using Groundwater Vistas version 6. Some data inputs were pre-processed using scripts in Python 2.7.6.0. Post-processing was done with both Groundwater Vistas and Python. \n\nModel parameters are informed by an amalgamation of data from the study area, but are not specific to any one location. Where there is a wide range of possible parameters, values from the Pike Floodplain have been adopted. Where no local field data exists, values were used from the literature and/or from DEWNR’s Salinity Register regional models.\n\nAs the Goyder Floodplain Model is a synthetic model, in that it does not model a specific location, no detailed calibration was possible.
