Taylor Engineering led an international consortium of Canadian, Bolivian, and Argentinean companies on a multidisciplinary environmental assessment of the impacts of the Hidrovia navigation project that, if completed, will open nearly one-third of South America to waterborne commerce. Under contract to the United Nations, Taylor Engineering examined potential alterations to ecological systems because of proposed navigation improvements along the 3,400 km river system that traverses five countries and includes the Rió Paraná and Rió Paraguay.

Taylor Engineering's primary work included collection, analysis, and interpretation of water and sediment quality samples; nine-year continuous simulation modeling of watershed runoff; flood wave routing, sediment transport, and pollutant loadings; and development of a GIS for the project area. Other tasks included a description of aquatic and terrestrial ecological communities from interpretation of satellite imagery and ground-truth investigation, the determination of ecologically sensitive areas, and recommendations to mitigate impacts that may result from project construction.
