About the Technique

The Australian Rainfall and Runoff Data Hub is a tool that allows for easy access to the design inputs required to undertake flood estimation in Australia. Background on the development and use of this data can be found in Australian Rainfall and Runoff (2016). The Data Hub accesses data that is © Commonwealth of Australia (Geoscience Australia) and published under CC BY 4.0. The data hub was not produced and is not managed as part of the Australian Rainfall and Runoff update.

To use the tool enter your catchment centroid in latitude and longitude or upload a shapefile. Note the shapefile must be in latitude and longitude projection (not MGA) to work with the hub, and you must group upload all of the shapefile components (not just the .shp, also the .shx and .dbf at a minimum) together. Next select the data you wish you attain from the tool by ticking the checkboxes or by hitting “Select All”.

Baseflow factors are not included in “Select All” as they are calculated for the contributing area upstream of a point and therefore should be calculated at the catchment outlet. If you need baseflow factors you should enter in the latitude and longitude of your catchment outlet and select Baseflow Factors as a separate request to the other data.

Now hit submit and a page will appear with your data, which can be downloaded as a csv-format text file at the bottom of the page. Also note that temporal patterns for your catchment will be zipped up and available for download by following the “Download (.zip)” link in the heading of the Temporal Pattern section of the results page.

Note the csv could be included as an appendix of your study to improve reproducibility of results.

Advanced Use:

API requests can also be sent to the server directly through the URL. The results of this style of request yield a text file similar to the one downloadable on the regular results page, with the temporal pattern increments also displayed at the end of the file.

The form of the GET request is as follows:

http://data.arr-software.org/?attribute1=value1&attribute2=value2

An example URL request to obtain all the data at (-29.573, 152.648) in latitude and longitude is as follows:

http://data.arr-software.org/?lon_coord=152.648&lat_coord=-29.573&All=on
