Project: WASA's Trinidad Groundwater Development Project

Client: Earthwater Technology Trinidad and Tobago LLC

Objectives:

• Develop custom tools that would allow resistivity data collected at hundreds of stations across Trinidad to be visualized in 3D.
• The ability to visualize resistivity data at all locations simultaneously was a key to understanding potential water-bearing zones.

Outcomes:

• The ability to visualize the resistivity data in 3D.
• Maximum return on data collection investment.
• New data integration tools previously not available for this type of data.
• Powerful visualization tools for communicating project and progress to clients and public.

Key Aspects:

• Developed a utility to efficiently upload ASCII resistivity data files at hundreds of locations across Trinidad.
• New functionality added to VIEWLOG to render 3D resistivity data
• Design of a database structure based on this data that could be used to render the data in 3D in VIEWLOG.

Project Description:

Low water levels during Trinidad's dry season have caused Trinidad to instate water restrictions across the country and current estimates project water sources to be depleted in a matter of months.  It is a fine balance until Trinidad's rainy season begins in May, when water sources can be replenished.  Earthwater Technology is searching for a new water source in a highly complex geologic area at the base of the Northern Range.

Conclusion:

3D visualizations will continue to enhance interpretations of site data by being able to see more data and their interactions simultaneously.  Visualizations are also a key factor in presenting the results to the public.
