Horizon consultants are expert at conducting stream and watershed assessments for a variety of objectives, including identifying and analyzing flooding risks, evaluating erosion and sedimentation issues, characterizing habitat and species needs, complying with regulatory requirements, creating maintenance solutions, and developing restoration approaches.
Our team of geomorphologists, hydrologists, ecologists, botanists, wildlife and fish biologists, and water quality specialists are knowledgeable across traditional discipline boundaries and can conduct comprehensive and integrated resource assessments working together or alone.
We have experience evaluating watersheds and developing watershed assessment reports and management plans. Our experience includes evaluating erosion and sediment source areas, water quality source problems, runoff generation, and stormwater management opportunities. We provide our clients with recommendations for managing sediment, including developing sediment basins, beneficial reuse of sediment, and reservoir sediment dredging and management.
The Horizon team is also experienced in developing vegetation management plans for watersheds, including fuel reduction and fire risk reduction plans.
We are comfortable assessing the full range of fluvial systems from small creeks to large rivers. Our work includes hydrologic and streamflow evaluations, geomorphic process studies (sediment textural analysis, sediment transport, hydraulic conditions, etc.), streambank stabilization analysis, as well as geomorphic form analysis (channel shape, instream complexity and habitat features, planform and cross-section analysis). We are particularly skilled at understanding and characterizing how a particular stream reach or segment functions within the overall watershed and identifying the constraints and opportunities of working with that segment.
