HUN groundwater flow rate time series 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.

The dataset includes a script and data for generating flow rate time-series figures for HUN GW modelling. The flow rate data points represent historical pumping rates and estimates of future pumping rates used to represent the impacts of coal mining on groundwater levels and surface water - groundwater fluxes in the Hunter subregion.

The script was written to generate time-series graphs of flow rates used in the HUN GW modelling for each mine in the Hunter subregion.

Dataset History

Historical mine water pumping rates and estimates of future flow rates were extracted from mining reports (groundwater modelling within mine Environmental Assessments) for each baseline and additional coal resource development modelled in the Hunter subregion. These flow rates are inputs to the groundwater model to represent the impacts of coal mining over time on groundwater (drawdowns and changes in surface water - groundwater fluxes).

A script was written to generate time-series graphs for each mine represented in the groundwater model. The full set of mining reports from which data were extracted and the time-series graphs generated from these data are included in Herron et al. (2016).
