An expert in the application of numerical models to catchments and floodplains, and was instrumental in the pioneering use of 2D hydrodynamic models for floodplain flow prediction and inundation mapping.


Grantley is Manager and Principal Engineer of the Water Research Laboratory. He is responsible for all commercial and applied research projects, financial operations, ongoing professional development of staff and the maintenance and development of WRL's facilities and techniques. 

Grantley is an Australian expert in the fields of physical and numerical modelling of water. In his 24 years as a professional engineer, Grantley has developed his skills on a broad range of projects providing assessment and solutions for water engineering and water resources investigations. He has particular expertise in the selection and application of appropriate numerical models to support design solutions, planning and management across the water spectrum. Numerical modelling projects have been undertaken using 1D, 2D and 3D hydrodynamic and water quality models. 

Grantley has specialist expertise in water resources management through a hands-on career investigating catchment processes. His experience gained through direct participation in the evolution of floodplain modelling has provided him with an outstanding knowledge of the application and interpretation of appropriate numerical models to support environmental planning, management and forecasting for floodplains. Grantley is a lead author and key contributor to reports supporting the revision of Australian Rainfall and Runoff, most recently contributing to guidelines for appropriate use of 2D numerical models to floodplains. He is also a co-contributor to guidelines setting safety criteria for people and vehicles in floods.
