HUN AWRA-L ASRIS soil properties 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.

The dataset is an extract for the Hunter subregion of the soil thickness data from the ASRIS Continental-scale soil property predictions 2001. The source data are the Surface of predicted Thickness of soil layer 1 (A Horizon - top-soil) surface for the intensive agricultural areas of Australia. Data modelled from area based observations made by soil agencies both State and CSIRO and presented as .0.01 degree grid cells.

The dataset consists of statistics for soils depths (MIN, MAX, RANGE, MEAN, STD, MEDIAN) for each of the simulation catchments in the AWRA-L model. The soil thickness data were resampled to the model grid (BILO cells - 0.05 degree grid cells) and the catchments are defined by the BILO cells which fall within them. The gauging station ID in the spreadsheet defines the gauges which were used to define the upstream catchment area.

Purpose

Used to define soils thickness in the AWRA-L model.

Dataset History

The soil thickness data were resampled to the model grid (BILO cells - 0.05 degree grid cells). Statistics for soils depths (MIN, MAX, RANGE, MEAN, STD, MEDIAN) for each of the simulation catchments in the AWRA-L model were calculated using the Zonal Statistics as Table tool within ArcGIS with the simulation catchments used as the zone dataset. The output table was used to populate the excel spreadsheet with the Station ID and catchments areas added.
