Stillwater Sciences specializes in fluvial and hillslope geomorphology, and routinely conducts sediment transport modeling, sediment source analysis, habitat parameterization, and assessments for directing restoration design.

Because of our focus on watershed science, Stillwater attracts the most qualified and well-respected fluvial geomorphologists working outside of academia. We use geomorphic principles to help understand relationships between organisms and their environment, provide mechanisms by which stream flow affects sediment movement downstream, and design and evaluate floodplain and channel restoration efforts. The broad-based background of our technical staff allows us to tackle many different questions and applications of geomorphology, including:

  • Geomorphic and geologic watershed mapping and interpretation
  • Sediment source inventories and sediment budget determinations
  • Historical records analyses and land use change impact assessments
  • Stream flow and sediment entrainment and transport monitoring
  • High-resolution flow velocity profiling
  • Channel geometry and bed profile surveys
  • Channel bed and subsurface sediment characterization including facies mapping
  • Numerical modeling of sediment transport dynamics in sand- and gravel-bed rivers
  • Numerical modeling of reservoir sediment deposition and stratification
  • Physical modeling (flume) experiments
  • Aquatic and estuarine habitat characterization and modeling
  • Large wood assessments and budgets,
  • Planning and designs for river restoration, gravel augmentation, instream habitat structure placement
  • Strategic planning for dam removal
  • Prescriptions for ecological high flow releases
  • Designs for ecological high flow implementation
  • Baseline and post-project monitoring and evaluation

These skills are applied to all aspects of the project process, including strategic planning, project orientation and conceptual model development, determination of current site conditions, interpretation of past site conditions, and prediction of future site conditions.  We work closely with colleagues and teaming partners to provide interdisciplinary biophysical and biogeochemical answers that are targeted directly at client questions and priorities.
