HUN AWRA-R Irrigation Area Extents and Crop Types 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.

Tabulated data with information on crop types and areas in each river reach in the Hunter river system model. This dataset was derived by the Bioregional Assessment Programme from existing catchment land use data obtained from the Australian Bureau of Agricultural and Resource Economics and Sciences.

Purpose

The AWRA-R river model needs details of irrigated areas and crop types in each river reach in which irrigation is present in order to determine areal extent and crop factors of the most common crop types .

Dataset History

Areas and crop types are obtained from the Catchment scale Land Use Management (CLUM). The dataset was clipped using catchment boundaries defined by the AWRA-R modelling domain and the information summarised by reach in order to determine crop types and associated crop factors . Irrigation areas are determined using the first level classification in the CLUM dataset which describes the main land use type. Crop types were determined from the third level classification, which provides detailed information on crop types.
