Hydrological Services include the provision of flood forecasting and warning services, hydrometeorology services in support of water resources management and assessment, and the provision of specialised advisory products for civil engineering design. These services depend heavily on the information collected through the Bureau's basic national meteorological observation networks. The Flood Warning Service also operates a special purpose network of rainfall and river-level stations in cooperation with state and local government agencies.

Hydrology Sections, incorporating Flood Warning Centres, exist in all Regional Offices of the Bureau. Overall coordination is provided by the Head Office Hydrology Unit, which also provides some services. Regional service delivery depends on close cooperation with state and territory water and emergency service authorities and local government agencies.
