HUN AWRA-R River Reaches Simulation v01

Abstract

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.

HUN AWRA-R River Reaches Calibration v01 depicts the 'blue line' drainage network used in the river model AWRA-R. It includes information on stream length for each river reach defined in the river model node-link network. This dataset was derived by the Bioregional Assessment Programme from existing 'blue line data' obtained from DPI Water (Riverstyles Spatial Layer for New South Wales).

Purpose

AWRA-R requires stream length of each stream within a river reach in AWRA-R in order to estimate model parameters related to in-stream losses and routing.

Dataset History

HUN AWRA-R River Reaches Calibration v01 is created from a river map of NSW (described in the lineage) which is overlain and clipped by a river reach map from the Topo250k dataset, which in turn is defined by a subset of streamflow gauges. Only the river network between upstream and downstream gauges (may have multiple upstream gauges) are considered, the rest are manually selected and removed.
