Environmetrics is the development and application of statistical and stochastic techniques in the environmental sciences. Research in environmetrics being pursued within the realm of time series modelling of water resources and environmental systems includes modelling seasonal hydrological time series using ARMA-type models, trend analysis of water quality data, environmental impact assessment, intervention analysis, forecasting, simulation, and transfer function-noise modelling. Moreover, graduate students are invited to participate in the interdisciplinary course SYDE 631 Time Series Modelling, which covers a wide range of interesting topics in time series modelling and analysis with illustrative applications in hydrology, water quality, and other fields that are of direct interest to the students.
