SYD ALL Unified Stream Gauge Data v01

Brief description

## **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.



This dataset was created to establish a unified streamflow dataset from the source dataset provided by the BoM. The data will be used for the summarising the streamflow characteristics in the South Sydney Basin context report and surface water and ground water modelling (if required).

## **Dataset History**

Data were extracted from the raw data .csv format to corresponding unified .csv files for surface water sites within the South Sydney Basin. The process steps are as follows

1.\tTo move one day backward to match precipitation data since the original 9:00am data is for the period of the current 10:00 am to next 9:00 am

2.\tTo identify gauge stuck issue

3.\tTo identify data linear interpolation issue

4.\tTo regard the issue data as missing data

5.\tTo generate streamflow data with the unified quality codes: (1: Good; 2: Fair; 3: Poor; 4: Unverified; 5: Non-conforming; 6: Missing)

6.\tTo separate daily streamflow into baseflow and quick flow using the standard filtering method (Lyne and Hollick (1979)).

The data was created in MATLAB using scripts and functions.
