Meteorological service of Canada

Research scientists from the Meteorological Service of Canada, hydrology section and from the Canadian Wildlife Service participated, between 2004 September 12 to 17, at the 5th International Symposium on Ecohydraulics organized by the International Aquatic Modelling Group (IAMG) in collaboration with the Eco-Hydraulic section of the International Association of Hydraulic Engineering and Research (IAHR).

The symposium, held in Madrid Spain, attracted more than 400 delegates from around the world that were gathered to exchange and share their knowledge and ideas on fluvial environments.

During the symposium, research scientists from the hydrology section organised a session of eight scientific presentations dedicated to research activities on the St. Lawrence River conducted by Environment Canada and its partners (EC-CWS, INRS-ETE, MRNFP, Univerdidad Nacinal del Nordeste, Argentine).

This showcase allowed the presentation of numerical modelling of physical parameters like water levels, water currents, wind waves and water temperature. In the same way, many presentations focused on numerical modelling of wetlands, fish habitat, floodplain fish reproduction habitat and bird habitat.

Scientific and technical advances developed with this approach that is based on the integration of knowledge and on the production of predictive environmental indicators, which are easy to use, were greatly appreciated by the scientific community. These advances illustrated, at an international level, the environmental modelling expertise of Environment Canada and its partners.

The research activities presented during the symposium were applied under the International Lake Ontario–St.Lawrence River Study sponsored by the International Joint Commission to assess, among others, impacts of the regulation of the Lake Ontario–St. Lawrence River system on the environment.
