Groundwater-Surface Water Interaction

dataset: GW_SW_INTERACTION
The Australian Hydrological Geospatial Fabric Surface Hydrology Catchments dataset was used as the base layer for considering surface water as an asset. This dataset provided mapped major rivers for Victoria. Numerous investigations into the interaction between groundwater and surface water have occurred across Victoria. Where this information was available in a format suitable for use in a GIS, it was collated to inform a state wide dataset of groundwater and surface water interaction. The resulting product attributes the stream base layer (described above) with the following classification of groundwater and surface water interaction: Gaining Variable Neutral/Losing Unclassified

Positional Accuracy
Accuracy of the boundaries varies across the state depending on the source data. Much of the source data has been derived from 1:100,000 to 1:250,000 scale mapping.

Statement
Dataset Source: The method used to generate the dataset of groundwater and surface water interaction in Victoria can be summarised as: (1) Where a hydrogeochemistry study by Monash University was available to provide an indication of groundwater and surface water interaction it was adopted with high reliability; (2) Where a Murray-Darling Basin sustainable yields groundwater and surface water interaction study was available, it was adopted with medium reliability; (3) Where Melbourne Water Corporation (MWC) had indicated river reaches characterised by remnant pools of water in prolonged drought, this was considered to be indicative of gaining river conditions, with medium reliability; (4) Where a baseflow indices study was available, it was indicative of a gaining river reach and assigned medium reliability; (5) Where no other information existed and the river was classified as "unmodified", it was assumed to be gaining if it was perennial and neutral/losing if it was not perennial. These river reaches were assigned a low reliability; (6) Where no other information existed and the river was classified as "modified", an indication of groundwater-surface water interaction could not occur, given that the modification of flows could be responsible for the perenniality of the river reach, as opposed to being indicative of losing or gaining groundwater; (7) A reliability dataset was also generated that indicates the assumed reliability of the classification, which was directly correlated to the reliability of the input data.
