Flow Matters provides specialists IT services to the water sector in Australia and internationally, with a focus on simulation modelling, data management and visualisation. We have been involved in the development and use of several key modelling platforms, including eWater Source, where we have contributed plugins as well as core performance improvements, and the AWRA Modelling System, where we provided the technical leadership throughout the development phase. We regular conduct data management and visualisation projects for water and environmental data, including numerous visualisation and decision support systems related to eWater Source and several national scale visualisation tools, such as the Landscape Water Balance (http://www.bom.gov.au/water/landscape/) and the Australia’s Environment Explorer (http://ausenv.online).
