The Department of Water and Environmental Regulation uses groundwater models to inform groundwater resource management across the State.
The Perth Regional Aquifer Modelling System (PRAMS) is a dynamically coupled recharge and groundwater flow model for the Perth metropolitan area. Its primary objective is to predict the impacts of groundwater abstraction, climate and land-use changes on a range of environmental and community assets throughout the region.
In July 2024, PRAMS was updated to . The update extended the history matching period to 2019 and used industry leading, automated parameter estimation techniques. This allowed a significant increase to model parameterisation and resulted in the best model fit to observed data seen so far in PRAMS.
