Project Overview

This was a collaborative project between WWLA and Bay of Plenty Regional Council (BOPRC). The primary objective was to develop a simulation model to support the review of regional policies for managing land and water resources within two key catchments.

Technical Solutions

A daily hydrological and water quality model was developed using the SOURCE modelling framework from eWater Australia. The project also utilised WWLA’s specialised Soil Moisture Water Balance with Vadose Zone functionality (SMWBM_VZ). This allowed for a more accurate simulation of the time lag in rainfall recharge and nitrogen leaching through the soil.

Client

The key outcome for the BOPR was the delivery of a sophisticated simulation model. This powerful tool provides the council with the detailed technical evidence and predictive capabilities needed to effectively review, test and inform regional land and water management policies.
