Flow characteristics for Namoi Surface water gauges

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis file contains values for a number of flow characteristics for selected stream gauges in the Namoi River catchment.\n\n## **Purpose** \n\nThe data was calculated to inform the investigation of surface water - groundwater interaction reported in the Namoi 2.1.5 product.\n\n## **Dataset History** \n\nMean daily discharge determined directly from source file.\n\n\n\nMean baseflow, Baseflow index and percentage of time river flows for the 2003 to 2012 period determined using River Analysis Package: Marsh, N. A. Stewardson M. J. Kennard, M. J. (2003) River Analysis Package, Cooperative Research Centre for Catchment Hydrology, Monash University Melbourne. \n\n\n\nPre-2003 data obtained from: Ivkovic KM (2006) Modelling groundwater-river interactions for assessing water allocation options, PhD Thesis, Australian National University. \n\n\n\nViewed 24 September 2012, https://digitalcollections.anu.edu.au/handle/1885/49342. Doctor of Philosophy Thesis, Australian National University, Canberra, Australia.\n\n\n\nDominant direction of flux determined from visual inspection of data, using method described in Ivkovic 2009\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2017) Flow characteristics for Namoi Surface water gauges.
