Modelling Groundwater with eWater Source


music by eWater logo

Overview

This two-day course introduces the approaches that can be used in Source to represent groundwater-surface water interaction. Participants learn analytical and numerical approaches to surface-groundwater interaction, including how they can be set up in Source and the benefits of each.

Prior knowledge of the Source modelling framework is not required. We will teach some Source model-building basics initially.

Topics covered in this course will include:

  • the analytical GW-SW interaction tool
  • the new numerical (1D finite difference) groundwater model
  • some simple examples of how these might be applied

The tools capture the impacts of GW-SW interactions on river flows such as surface water irrigation and groundwater pumping, and floodplain interactions.

A fundamental feature of Source is that it is readily customisable. New capabilities can be incorporated via plugins developed to suit particular needs while maintaining a consistent overarching decision and policy framework. The potential for other groundwater functionality to link with Source will also be discussed.

Who should attend

This course is appropriate for those who have an interest in evaluating groundwater–surface water interactions for their impact on river and stream flows.

It is of particular benefit to:

  • Groundwater hydrologists who would like an easy-to-use approach to represent GW-SW interactions of major rivers and to estimate the resultant fluxes. These might be used to provide basin-level estimates of a flux or to compare to more complex groundwater investigations (e.g. those using MODFLOW models).

  • River system modellers who would like to have an improved representation of GW-SW interaction in river system models. This may improve the calibration of river system models to gauged river flows in reaches where GW-SW interaction is significant.

Requirements

  • Prior knowledge of the Source modelling framework is NOT required.

Trainers

Dr Carl Daamen
Principal Hydrologist

Day One

Participants will be introduced to the Source user interface and basic functionality. By the end of the first day, participants will be able to:

  • understand the theoretical concepts underpinning Source and outline its general modelling capabilities
  • describe the node-link structure of all source scenarios, describe the similarities and differences between schematic and geographic scenarios, and their appropriate applications
  • navigate around various screens, panels and toolbars in Source
  • construct a model from nodes and links
  • edit and parameterise a node model, record elements, and configure and run a scenario
  • view scenario outputs in graph, table and statistical formats.

Day Two

Participants will be provided with an overview of the groundwater modelling tools available in Source, including their conceptual basis and limitations. By the end of the second day, participants will be able to:

  • choose an appropriate groundwater model considering project objectives and data availability

  • set up and configure an Analytical Groundwater Model on a river link, including configuring flux input, groundwater head, unsaturated connection and saturated connection models

  • set up and configure a Numerical Groundwater Model on a river link, including connecting diffuse recharge sources, extraction points and water users.
