Total Daily Stream flow Sydney Catchment Authority 20141211

Brief description

## **Abstract**

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied.

The metadata was not provided by the data supplier and has been compiled by the programme based on known details at the time of acquisition.



This is a special data request to Sydney Catchment Authority for daily total flow data fom every gauge for as long as possible for all SCA/SW guages to calibrate AWRA-L for the Sydney Bioregional Assessment.

Daily total discharge for each gauge, with a day = 0900 day_j to 0900 day_j+1



Please note that river level height for the same gauges can be found in the following file which was aquired on 27th July 2015 and requested from Sydney Catchment Authority:

## **Purpose**

This is a special data request to Sydney Catchment Authority for daily total flow data to calibrate AWRA-L for the Sydney Bioregional Assessment.



"Variable 151.01 is a total daily flow volume which was manually computed years ago and stored in Hydstra as a flow value (someone had to type these in ... and convert from gallons or acre feet or whatever the original values were).

Variable 151 is a total daily flow volume computed by Hydstra from the recorded level values and the applicable rating curve for the time. Where the two sets of values overlap, they will be slightly different due to the different calculation methods, the simplifications made in the manual calculation, perhaps some information available at the time of the manual calculation that has not been digitised, or that has simply been lost in the mists of time."

## **Dataset History**

Special Data request to Sydney Catchment Authority by the Bureau of Meteorology through the Water Act. Data created by querying SCA's internal systems/Databases.

Data provided in excel files in CSV format.
