The impact of land use change on catchment hydrology in large catchments: The Comet River, Central Queensland, Australia

Level 1 General description


To determine the level of impact land use change has on flow and runoff in properties adjacent to the Comet River.

Methods (brief)

A simple conceptual daily rainfall-runoff model, SIMHYD, was calibrated for the pre-clearing period using various calibration strategies and used to estimate runoff in the post-clearing period.

An annual water balance model was also used to determine the effects of clearing on runoff volumes.

Key findings (brief)

An annual water balance model using a standard hyperbolic function indicated that runoff in the post clearing period was greater by 58% than if clearing not occurred.
