Why is Conceptual Modeling Important?

Conceptual modeling allows today’s professionals to streamline the model development process. This relatively new approach can increase efficiency specially when creating the numerical grid, defining model parameters, and assignation boundary conditions. The main benefits of conceptual model development include:

  • Better understanding of the groundwater flow system prior to transforming the conceptual model to a numerical model
  • Defining a model using GIS objects is much faster than the traditional cell-based approach
  • If the numerical model is modified, the model inputs can be easily regenerated from the conceptual objects
  • From the same conceptual model, you can generate multiple numerical models, of different grid types 

Hydro GeoAnalyst* (HGA) helps ease the conceptual modeling process. However, you can expect an exciting new technology from SWS in the coming months. Stay tuned!

Using Hydro GeoAnalyst v4.0 with Visual MODFLOW v4.3


There are several ways that the data from a Hydro GeoAnalyst project can be used to create a Visual MODFLOW model including building the conceptual model layers and importing observation well data. 
The conceptual model layers can be generated in HGA using the HGA project data.  In HGA, you can query the database to determine layers with different lithology and export this data for use in a Visual MODFLOW model.  In the example below, the HGA database is queried to determine the bedrock elevation.  This can be determined by the stations in HGA that contain lithology data.

The conceptual model for this groundwater flow system can be summarized as below:


q

To query the bedrock surface, we will need to do the following calculation:

  Ground Surface (station.elevation)
– Top of Bedrock (depth to shale or limestone = lithology.from_ [shale/limestone])
= bedrock surface elevation

q Once the database has been queried to determine the bedrock elevation, a gridded surface can be created in the HGA Map Manager and then used in Visual MODFLOW.  In HGA, load the query into the Map Manager and create a gridded surface of the data (.grd file).

It is also possible to export the model layers created in the cross section editor.  Once you have created all of the cross sections for the project and defined the model layers, select File>Export Model Layers in the Cross Section Editor.  You can choose which layers to export and from which cross sections:

The more cross sections you define, the more points you have for defining the layer interfaces in Visual MODFLOW. The model layers will be exported as a text file with x, y and z values.

In HGA, you may also define the calibration points (water levels or concentrations in observation wells) for Visual MODFLOW.  You can create a calibration point file that can be imported into Visual MODFLOW by creating an HGA query.

q

In Visual MODFLOW, you will need the following columns (with an example) to import observation wells:

      Name        X            Y          Screen        Measure Point Elev        Stop Time      Head
      BH0902     2438       6556     1                       580.1                               1                 602.55

Below is an example of a query to use to obtain the required information from the HGA database:

q Once you have created the appropriate query, you may export the data from HGA to an excel spreadsheet or text file to import into Visual MODFLOW.

In Visual MODFLOW, you will need to set up the model with the appropriate model or world coordinates so that the files imported from HGA will correspond with these coordinates.  Create the model and import the model layers as layer surfaces.  Import the head observation wells into Visual MODFLOW using the query created in HGA.  The calibration points from these wells will be used in Visual MODFLOW to determine how closely the observed values fit with the values calculated by Visual MODFLOW.
