Brief description

A numerical groundwater flow simulation model for the Lockyer Valley alluvial aquifer. The model was developed using the MODFLOW-NWT software package, in conjunction with parameter estimation software PEST and its utility software. The calibrated model simulates the aquifer responses to a set of groundwater stresses including groundwater extraction, irrigation recharge, and flood recharge.

Lineage

The Lockyer model is built on and is an extension of a pre-existing model developed by Kellogg Brown and Root Pty Ltd to assess the sustainability of the water resource system in the Lockyer Valley (KBR, 2002). The KBR model was revised and extended to address the identified shortcomings, and to make use of the additional aquifer monitoring undertaken since the previous modelling period which ended in 2000. In addition, the model was altered so that it was able to serve as a PRW predictive tool. Specifically, these alterations comprised:
- use of a new DEM with a finer resolution (Harris, 2008) and existing strata logs to redefine the top and bottom elevations of the aquifer;
- inclusion of post-2000 groundwater level monitoring data, water use monitoring data, and river loss gauging data in the calibration data set;
- creation of a more detailed physical representation of model parameters in terms of hydraulic properties, river recharge and rainfall recharge;
- inclusion of knowledge from recharge estimation studies conducted for this UWSRA project.
- uncertainty and data worth analysis.
- application of the model to compute optimal PRW import volumes.
