This User Guide provides: ? information on operating WaterCAST, including specifying catchment geometry, selecting component models, running a project and viewing results ? an overview of broad catchment modelling concepts and the concepts underlying WaterCAST ? tutorials for operation of WaterCAST ? information on data formats compatible with WaterCAST

WaterCAST provides a flexible approach to whole-of-catchment modelling, supporting the creation of integrated models through the selection and linking of component models of a complexity appropriate to the management or research questions being addressed, and the available data and knowledge. This manual provides information on some of the analysis methods (e.g. network geometry) and the component models available within WaterCAST. Models are grouped according to function, with the groups being: ? Rainfall Runoff ? Constituent Generation ? Filters ? Links ? routing and storages ? Links ? processing ? Nodes
