Hydrogeomorphology \u2014 the discipline that studies the action of water as an agent of landscape transformation \u2014 provides the foundational diagnosis: how the watercourse functions, what erosion and sedimentation processes are at work, and what its mobility and likely evolution are. But this diagnosis, however precise, is not sufficient on its own to design a lasting intervention.<\/p>\n\n\n\n
A hydrogeomorphologist can identify that a riverbank is actively eroding, but a biologist is needed to determine whether that bank supports sensitive wildlife habitat. The geomatician provides the spatial dimension that situates the problem within its watershed and detects trends invisible from the ground. The fluvial hydraulics engineer translates all of these findings into an engineering solution that accounts for every constraint. It is this continuous interaction between disciplines that produces truly adapted solutions.<\/p>\n\n\n\n Avizo’s HGM Team: Four Disciplines, One Goal<\/strong><\/p>\n\n\n\n The team is made up of 4 dedicated hydrogeomorphologists \u2014 a rare concentration of expertise in Qu\u00e9bec \u2014 but its real strength comes from its integration with Avizo’s other specialists. In practice, from the very start of a mandate, our hydrogeomorphologists work closely with biologists who assess ecological impacts, conduct faunal and floral inventories, and identify environmental sensitivities; geomaticians who produce high-precision environmental mapping through remote sensing and spatial analyses; and fluvial hydraulics engineers who handle numerical modelling (1D, 2D, 3D), river ice analysis, and infrastructure design.<\/p>\n\n\n\n The key phrase here is “from the very start.” At Avizo, multidisciplinarity does not come at the end of the process as a “validation.” It is present from the diagnostic phase, allowing each discipline to influence the working assumptions of the others and to produce a coherent overall diagnosis.<\/p>\n\n\n\n How the Synergy Works in Practice<\/strong><\/p>\n\n\n\n Consider a typical example: a mandate to restore a watercourse in an agricultural setting. The hydrogeomorphologist first establishes the functional diagnosis of the watercourse \u2014 sediment budget, mobility analysis, identification of active erosion processes. At the same time, the geomatician produces a detailed watershed map that reveals spatial dynamics that ground-level observation cannot capture. The biologist identifies sensitive habitats and species present, guiding restoration choices. The fluvial hydraulics engineer models flow conditions to validate scenarios and size the structures.<\/p>\n\n\n\n The result? A solution that respects the natural dynamics of the watercourse, protects wildlife habitats, is hydraulically calibrated, and integrates into the territorial context. No single discipline could have produced this outcome alone.<\/p>\n\n\n\n A Philosophy: Working With the River, Not Against It<\/strong><\/p>\n\n\n\n Avizo’s multidisciplinary approach is rooted in a broader philosophy: promoting the equilibrium of watercourses to ensure the long-term viability of infrastructure and land uses. In practice, this means minimizing interventions by targeting only truly necessary actions, maximizing the physical and ecological health of watercourses by respecting their natural processes, and accommodating foreseeable hazards related to erosion, sedimentation, and flooding rather than attempting to eliminate them.<\/p>\n\n\n\n This philosophy can only exist within a multidisciplinary framework. It is the combined perspective of the hydrogeomorphologist, the biologist, the geomatician, and the engineer that makes it possible to determine what is “truly necessary” and to design solutions where bioengineering, hydraulic modelling, and field science work in harmony.<\/p>\n\n\n\n Integrated Services, Never Siloed<\/strong><\/p>\n\n\n\n Thanks to this multidisciplinary team, Avizo offers services that feed into one another rather than being delivered in isolation.<\/p>\n\n\n\n Hydrogeomorphology: diagnostic studies, sediment budgets, watercourse restoration, mobility assessments, fluvial dynamics characterization, riverbank erosion analysis, and geomorphological risk evaluation \u2014 enriched by ecological and spatial data from our biologists and geomaticians.<\/p>\n\n\n\n Numerical hydraulic modelling (1D, 2D, 3D): flow simulation under normal and extreme conditions, floodplain mapping, impact assessment of infrastructure \u2014 calibrated by field observations from our hydrogeomorphologists.<\/p>\n\n\n\n Ecological studies: faunal and floral inventories, habitat assessment, environmental monitoring, and compensation plans \u2014 guided by a geomorphological understanding of the environment.<\/p>\n\n\n\n River ice: analysis of ice dynamics, ice jam risk assessment, and design of mitigation measures \u2014 integrating hydraulic and geomorphological data.<\/p>\n\n\n\n Environmental mapping: remote sensing, geospatial analysis, thematic map production \u2014 serving all disciplines for a comprehensive territorial vision.<\/p>\n\n\n\n![\"Avizo](\"https:\/\/www.avizo.ca\/wp-content\/uploads\/2026\/03\/IMG_4612-1024x768.jpeg\")
