GeoSystems Analysis, Inc. (GSA) has pioneered innovative solutions for industry and government since 1994.  We are a small business with offices in Arizona, New Mexico, Colorado, Oregon and Antofagasta, Chile; serving clients in the federal, tribal, state, municipal, non-profit and private business sectors.  Our staff is composed of interdisciplinary scientists in the fields of soil science, surface and ground water hydrology, botany, riparian-wetland ecology, fire ecology, and rangeland science.



Our firm provides hands-on experience, highly trained personnel and cutting-edge research. Our clients benefit from our laboratory, field-based and computational solutions for unsaturated flow, groundwater resource and land reclamation issues.

Our Tucson, Arizona headquarters office hosts a soil physics laboratory, where we perform applied research on soil-water interactions, contaminant mobility and transport.



GSA offers our clients a full range of water resources and ecological services, from groundwater recharge, mine reclamation and hydrology, habitat restoration, watershed and conservation planning to the design and implementation of rigorous monitoring programs.  We work with clients to understand their specific land and water management challenges, and respond with pragmatic solutions founded on sound scientific principles.



Habitat Restoration

GSA provides a full range of habitat restoration support services, including characterizing site conditions, developing restoration plans, writing grants and developing project funding strategies, managing and overseeing project implementation, and performing effectiveness and validation monitoring to support both programmatic and project level adaptive management planning.




Ecological Monitoring & Applied Research

GSA specializes in scientific investigations of plant-soil-water relationships to develop solutions for a broad-range of watershed management challenges.  We routinely customize field instrumentation for special project needs, design and conduct field and laboratory experiments, and perform soil chemical, hydraulic, and physical analyses in our Tucson-based soils laboratory.  




Watershed Analysis and Management

GSA scientists provide interdisciplinary expertise with watershed-scale analysis and management planning.  Some examples include performing landscape analyses to prioritize habitat restoration locations, evaluating the potential for forest fuels treatments to reduce post-fire flood risk, assessing landscape conditions to guide rangeland management planning, and developing environmental flow prescriptions for regulated rivers.
