Sediment Transport —Understanding Erosion, Protecting Infrastructure

Sediment doesn’t just move downstream — it reshapes channels, undermines bridges, clogs infrastructure and changes legal liabilities.

The study of sediment is a critical field relating to the physical characteristics and processes that shape our rivers and streams. Understanding the geomorphology of rivers is essential for integral solutions in a wide range of water resources, floodplain planning, environmental protection and infrastructure development. This understanding helps to provide insight into the way that rivers interact with their surrounding landscape.

High Water Mark offers sediment transport analysis that connects geomorphology with engineering, permitting and litigation strategy. We have the understanding to mitigate the impacts of natural events such as floods and droughts as well as understand the impact of human activities on rivers.

  • Watershed Studies
  • Advanced 1D/2D Modeling
  • Computational Fluid Dynamics (CFD)
  • Bridge Hydraulics
  • Scour Analysis
  • Sediment Transport
  • Open Channel Design
  • Dam Break Flood Analysis
  • Impact Analysis
  • Geomorphology
  • Mud and Debris flow Modeling
  • Channel stability assessments
  • Sediment yield estimation for development sites
  • Reservoir and culvert sedimentation analysis
  • Expert reports for regulatory compliance and court testimony

Work Grounded in Nuanced Understanding

Sediment transport is often overlooked until it becomes a problem. We help clients get ahead of issues with clear, defensible modeling and actionable mitigation strategies.

Our work is grounded in a nuanced understanding of stream dynamics, watershed processes and infrastructure vulnerability. Whether evaluating a failing channel near a roadway or analyzing upstream land use impacts on sediment load, we trace the cause — and recommend corrective action.

High Water Mark serves municipalities, attorneys and engineers needing to quantify sediment impacts for infrastructure design, permitting or dispute resolution. We don’t just explain what the stream did — we show why and what it means for the system as a whole.
