Comparison of Seasonal Flow Rate Change Indices Downstream of Three Types of Dams in Southern Quebec (Canada)

The objective of this study is to use two hydrological indices (coefficients variation and immoderation) analyze the impacts dam management methods on seasonal daily flow rate change downstream three dams: Manouane (diversion-type method), Ouareau (natural-type method) Matawin (inversion-type method). results show that far greater (characterized by an inversion-type than other dams. Moreover, dam, increases significantly over time, while decreasing dams in natural rivers. Lastly, better correlated with climate It positively winter spring temperatures as well summer fall rain. Contrary commonly accepted hypothesis, shows generally result increase Quebec.
