The 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.
This file contains values for a number of flow characteristics for selected stream gauges in the Namoi River catchment.
The data was calculated to inform the investigation of surface water - groundwater interaction reported in the Namoi 2.1.5 product.
Mean daily discharge determined directly from source file.
Mean 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.
