Fields of activities of the Quebec Hydro Expertise Center - CEHQ
Following the exceptional flooding in July 1996 in the Saguenay-Lac-Saint-Jean, Capitale-Nationale, Mauricie and Côte-Nord regions, the Center d'expertise hydrique du Québec (CEHQ) undertook Development and operation of a system for forecasting the level and flow of certain rivers in southern Québec. This system includes watercourses in certain watersheds where dams are operated by the MDDELCC, as well as the water system of the archipelago of Montreal. Following the flooding of the Richelieu River in 2011, this prediction system was progressively extended to hydrometric stations in southern Québec that are not influenced by the operation of the dams. Since 2016, this system is under the responsibility of the Water Expertise Department (DEH) of MDDELCC.
The purpose of hydrological forecasts is to allow for more informed planning of interventions for both flood and low water events and for more frequent hydrological conditions. For the management of public dams, the forecasts make it possible to adapt the operation of the dams in the face of climatic and hydrological hazards, in order to respect the management plans. For rivers not influenced by dams, forecasts can be used to formulate opinions or to issue civil security alerts with a certain amount of anticipation, which allows a more rapid and efficient handling of the interventions on the ground.
