The diagrammatic interface to each module of the Water Accounting Systems (WAS) is shown in the associated figures, where barrels represent stock variables, pipes represent flows, and parameters such as intensities are hexagons. Stocks generally refer to the accumulated amounts of physical entities, such as storage volumes or land areas, while flows are the changes in physical entities within each time-step of the simulation. In addition to the descriptive title of each variable, the figures show abbreviated names for the dimensions of the disaggregated variables; two common ones are: “wrv” for “water region Victoria” and “ts” for “time of simulation”. The variables are either inputs or outputs of the numbered procedure boxes which contain the code for calculating the outputs. The connectivity between modules in the water account is indicated by the yellow tags (with abbreviated module names) on those variables in one module that are passed to other modules. The WAS has been created and is operated in a “whatIf” software environment (whatIf Technologies Incorporated; available from: that is designed to support: large multi-dimensional data objects; model development and simulation; a diagrammatic user-interface; and creation, management and analysis of scenarios.
