GeoTrans houses the largest, most experienced pool of expert groundwater modelers in the country. Over 50 modelers with an average of 12 years experience have applied their expertise in areas such as water resources management/optimization, assessing the impacts of salt water intrusion on water supplies, and, aquifer storage and recovery feasibility assessments.

We are experts in the use of MODFLOW and have integrated it with Arc/Info ArcView pre- and post-processing tools to allow a uniform framework and data repository to be used in all aspects of water resource modeling. This makes our efforts dynamic-allowing additional data to be easily integrated into models and effectively conduct "what-if" scenarios crucial to the success of well field management plans.

For water supply development, we have be providing our clients modeling services for over 20 years helping them:

• Better understand aquifer characteristics and the groundwater flow system
• Reduce data collection by focusing on water management objectives
• Save on construction costs by efficient identification of well placement
• Reduce facility design costs by making reliable predictions of future site activities
• Achieve operational cost efficiencies by designing a water system with optimal functionality

GeoTrans has developed a variety of software packages for groundwater flow, transport modeling, GIS and data management.

• Modflow Lake Package - Free Lake Package for MODFLOW
• MDR - MODFLOW Data Reader
• MODMAN - Three-dimensional optimization module for MODFLOW
• SWIFT for Windows - Three-dimensional coupled flow, heat and contaminant transport code
