JEF provides a number of unique specialized services closely related to surface water hydrology and fluvial geomorphology.
A few of these services include:
- Stream Navigability Studies
We have performed 100’s of title navigability studies on streams in Arizona, Alaska, California, Nevada, Utah, North Carolina, and Montana. These studies include reconstruction of statehood-era hydrologic and geomorphic stream conditions, evaluation of historical and archaeological records of river usage, and analysis of modern boating. - Litigation Support & Expert Witness Services
We perform forensic and causal analyses, determine impacts of flooding and development, and provide court testimony to attorneys, insurance providers and individuals. - Riparian and Sovereign Boundary Determination
These analyses determine the limit of public/private ownership along navigable streams and lakes. - Technical Training
We offer technical training classes in a wide variety of drainage and regulatory related topics. - Engineering Manuals & Guidelines
We have prepared hydrology, hydraulics, erosion, floodplain, alluvial fan, and development engineering guidelines for a variety of public agencies in the western United States.
