Catchment Modelling in E2 and the eWater CRC Modelling Toolkit
Abstract
The Cooperative Research Centre (CRC) for Catchment Hydrology made considerable progress in development of an integrated catchment model for quantity and quality of runoff with the EMSS and E2 modelling systems. E2 has been available on the Catchment Modelling Toolkit website for over 12 months and more than 60 people have been trained in applying E2 to their catchment modelling applications. The new eWater CRC are working on the evolution of catchment water quantity and quality modelling in a dedicated product development project. This paper has two aims: to discuss innovations in the past and present application of E2 to real catchments and to outline the vision for future development of E2 by the eWater CRC.
The paper describes calibration and application of the E2 model to estimate flow and nutrient loads. It discusses the use of The Invisible Modelling Environment (TIME) to develop new algorithms for sewerage treatment plant discharge and automated processing of results from E2. The paper goes on to outline the plans and progress of the eWater CRC in developing catchment models that have improved modelling of groundwater/surface water interaction, constituent generation and transformation and use of stochastic climate data and model parameters. It will also describe improvements to the software interface that will enhance model set up and reporting and analysis of results.
