Abstract
AbstractDuring the prereservoir years, when limited data (neighboring basin flow and simulated flow) are available for ungauged basins, simple methods are relevant to reconstruct natural flow (NF). On the other hand, for the postreservoir years, when hydrometric data (water level in the reservoir, turbine flow, and discharged flow) are available for ungauged basins, the classic water balance equation (WBE) method is usually employed to determine NF. However, applying classic methods still produce noisy and unreliable flow data series. In an attempt to produce more reliable NF data, new methods are proposed and described in Part 1 of this paper: the state fusion Kalman filter method (prereservoir construction period) and the deterministic WBE method and the stochastic WBE method (postreservoir construction period). This paper that is presented as Part 2 deals with the execution of these new methods for three subbasins of different sizes in Quebec, Canada. Obtained results are then compared against those pr...
