Change detection in hydrology


The quantity and quality of water in our streams is dependent on many factors including climate, land use and management.  This leads to questions about how much impact have these factors have had on the stream water, particularly when these factors change through time.  For example, does afforestation impact on how much water is in our streams? Did the 2013 bushfires around Sydney have an impact on quality of water flowing into Lake Burrajorang?  These questions are difficult to answer given the large natural variability present in water data making it difficult to disentangle variation due to a factor causing the change and the natural background variation.  This project will explore approaches to detect change in hydrological time series data

Research location

Sydney Institute of Agriculture - Australian Technology Park

Program type



The project will be computer based and use datasets from around Australia to compare existing methods for detecting change in time series data.  From this a generic and robust approach will be developed for detecting change.  Both water quality and quantity datasets will be considered, as will statistical and mechanistic modelling approaches.  The student will gain valuable experience in analysing hydrological data using statistical and mechanistic models.  Experience in statistical modelling and the R software package is preferred
