Model setup for fracture flow and transport in limestone aquifers
Scales
Geologic modeling
Boreholes can give valuable information about the geology. Bits of geologic knowledge can be connected to establish a geologic model, that shows different geologic layers, to which properties can be assigned, and other relevant geologic information.
Modeling steps
This chapter gives step-by-step instructions for the setup of a model to simulate flow and transport in a fractured limestone aquifer. The following list shows the typical steps to setup a model for contaminant transport in a fractured limestone aquifer:
- Conceptualization and setup of a conceptual model
- Formulation of the modeling objectives
- Choice of model complexity and modeling scale
- Delineation of the model domain
- Data acquisition - measurements to obtain relevant model parameters (see list of parameters for each model)
- Implementation of parameters for selected units in the model domain (homogeneous/heterogeneous)
- Choice of boundary conditions for the flow and the transport model
- Setup of sources and sinks: Definition of wells
- For transient models: definition of initial conditions
- Mesh generation
- Simulation
- Critical evaluation of the modeling results
- Formulation of mass balances to check the model

The typical workflow will be demonstrated using an example field site close to Copenhagen. Example: Setup of models for a field site (Akacievej, Hedehusene)
