ABOUT US
Six Rivers Geosciences is a small, women-owned business located in Humboldt County, California, providing earth and geoscience consulting services to public and private clients. We have extensive consulting expertise in geotechnical and engineering geology, geomorphologic studies, geologic mapping, geohazard and environmental assessments, and hydrogeology for large-scale transportation and infrastructure projects. Our multidisciplinary expertise; comprehensive understanding of local, state, and federal regulations; and commitment to quality allows us to develop and deliver technically-excellent solutions to complex and challenging geoscience problems.
Jennifer Mendonça Wilson, PG, CEG, CHG
Principal Geologist
Ms. Wilson is a geologist with more than 18 years of experience working on the planning, execution, and management of environmental, hydrologic, geotechnical engineering and engineering geologic projects for local, federal, and state agencies, and private clients. She has extensive experience with levee, flood control, and water conveyance studies, geotechnical investigations, geohazard assessments, probabilistic seismic hazard analyses, groundwater and hydrologic studies, environmental assessments, surficial mapping projects and subsurface investigations utilizing a variety of exploration methods, including exploratory borings, fault trenching, CPT, test pits, and remote sensing. She has significant experience describing soil and rock properties using Unified Soil Classification (USCS), International Society for Rock Mechanics (ISRM), ASTM International, Caltrans, California Department of Water Resources, and United Stated Bureau of Reclamation (USBR) methods.
Ms. Wilson has also worked on numerous earthwork observation and testing projects associated with the construction phase of geotechnical investigations, including mass grading associated with slope rebuilds and landslide mitigation, design and build foundations in expansive materials, trenching, basement excavations, and soil nails/tieback installation. In addition, Ms. Wilson has extensive field experience in a wide range of diverse terrains and has more than four years of GIS and geologic research experience with the U.S. Geological Survey and NASA.
