In the study presented, to define monthly rainfall-runoff relation, a water budget model based on Budyko approach was used. Proposed five-parameter model requires only monthly mean precipitation and potential evapotranspiration data as input. The stu

Nonlinear Muskingum method is a very efficient tool in flood routing implementation. It is possible to estimate an outflow hydrograph by a given inflow hydrograph of a flood at a specific point of the river channel. However, it turns out an optimizat
