| Sumario: | <p>The objective of this study is to model the Mono River basin at
Athiémé using stochastic approach for a better knowledge of the
hydrological functioning of the basin. Data used in this study consist of
observed precipitation and temperature data over the period 1961–2012 and
future projection data from two regional climate models (HIRHAM5 and REMO)
over the period 2016–2100. Simulation of the river discharge was made using
ModHyPMA, GR4J, HBV, AWBM models and uncertainties analysis were performed
by a stochastic approach. Results showed that the different rainfall-runoff
models used reproduce well the observed hydrographs. However, the
multi-modelling approach has improved the performance of the individual
models. The Hermite orthogonal polynomials of order 4 are well suited for
the prediction of flood flows in this basin. This stochastic modeling
approach allowed us to deduce that extreme events would therefore increase
in the middle of the century under RCP8.5 scenario and towards the end of
the century under RCP4.5 scenario.</p> |
