RZWQM2 (Root Zone Water Quality Model 2) is a whole-system model for studying crop production and environmental quality under current and changing climate conditions. It emphasizes the effects of agricultural management practices on physical, chemical and biological processes. Crop simulation options include the generic plant growth model, DSSAT-CSM 4.0 and HERMES SUCROS models. It also can simulate surface energy balance with components from the SHAW model and water erosion from the GLEAMS model. An automated parameter estimation algorithm PEST is also added to RZWQM2 for objective model calibration and uncertainty analysis.
This tool enables researchers and users to benefit from the full capabilities of RZWQM2, directly from the browser, without any installation setup. As per the recommendation of RZWQM2 developers, you can keep your projects under H: drive, which already has a sample project loaded. In order to upload your own pre-configured scenarios, please follow the manual under Supporting docs.
