Hydrogeological assessment for integrated understanding of groundwater flow and solute transfer pathways

Hydrogeological assessment for integrated understanding of groundwater flow and solute transfer pathways

Specifications

  • Scope:

    Building on prior work, develop an integrated understanding of groundwater flow and solute transfer pathways for a target irrigation property including:

    • Hydro-chemical modelling
    • Groundwater flow and solute transport modelling
    • Groundwater impact risk assessment
    • Development of a groundwater monitoring plan

    The FLAG Upness procedure (Fuzzy Landscape Analysis Geographic information system) was employed to extrapolate data from readily available spatial layer to predict occurrence of likely discharge sites (seeps).

  • Challenge:

     A reliable cost-effective approach to predicting groundwater flow paths resulting from deep drainage associated with irrigation development was critical to forecasting potential downstream impacts.

  • Solution:

    In addition to conventional groundwater modelling approaches, Verterra also introduced the FLAG Upness procedure (Fuzzy Landscape Analysis Geographic information system), to identify and predict potential discharge (seep) sites. Ground-thruthing confirmed the modelled predictions.

     
  • Benefit to Client:

    This project provided the client with technical information on the likely impacts of irrigation development on surface water groundwater and land resources to support critical information requirements for compilation of a Beneficial Use Plan.
