Surface Water Hydrology
The department has developed detailed surface water hydrology studies for specific areas across Western Australia, using the best hydrological information, to successfully manage and allocate surface water.
The following reports will help you to understand how catchments, geology, land use and climate, influence hydrology throughout the South West region. They will also assist you to understand the methods we use to determine hydrologically available and sustainable volumes of water within a resource.
If you're interested in South West rivers and want to know how hydrology has changed over time, then read our hydrology summary reports
If you want to know how we determine how much water is available for allocation, our reservoir simulation reports delve into the details behind the modelling we do for our large reservoirs.
