Riverine Design Expertise

Ice Forcing Structures

Brailey Hydrologic provides specialized analysis of ice-induced forces on bridges, culverts, piers, and other riverine infrastructure in cold-region environments.

 

Our services combine field observations of ice conditions, freeze-up and breakup processes, and site hydraulics with numerical modeling to quantify ice loading, impact forces, and potential failure mechanisms.

 

Results are used to develop practical and defensible protection measures, including  deflection systems, and erosion/abutment protection strategies.

Culvert and Bridge Crossings 

We provide hydraulic analysis and solutions for culverts and bridge crossings, supporting safe, resilient, and cost-effective infrastructure.

 

Our services include hydrologic analysis of design flows, hydraulic modeling, culvert sizing and inlet/outlet control evaluation, bridge opening analysis, scour assessment, and flood conveyance optimization. We can evaluate sediment transport, debris passage, and ice impacts where applicable to ensure reliable long-term performance.

 

Our solutions meet DOT and regulatory requirements while balancing constructability, hydraulics, and environmental constraints.

Erosion Protection and Training Structures

We provide analysis for riverbank stabilization and channel protection systems throughout Alaska, supporting resilient infrastructure in dynamic river environments.

 

Our services include riprap armoring, articulated concrete block (ACB) systems, sheet pile walls, and revetments, as well as river training structures to control flow alignment and reduce erosion risk.

 

We integrate hydrologic and hydraulic modeling, field assessment, and geomorphic evaluation to develop cost-effective, constructible solutions tailored to site-specific flow and sediment conditions. 

Fish Passage Design

Brailey Hydrologic provides specialized design solutions that can meet Alaska DOT, U.S. Fish and Wildlife Service (USFWS), and U.S. Forest Service fish passage requirements.

 

We use hydraulic analysis, site-specific channel assessments, and aquatic organism passage criteria to ensure continuity of flow, sediment transport, and habitat connectivity. We evaluate slope, velocity, depth, and substrate conditions to review embedded culverts, stream simulation design, and bottomless structures.
