“…In recent years, several studies have documented hydrological forecasting using one or more datadriven methods and time series models (Nourani et al, 2014). Among various data-driven models, Genetic models such as Genetic Programming (GP) and Genetic Expression Programming (GEP) could produce incredibly accurate results in a wide range of hydrological modeling (Mohammad-Azari et al, 2020). Based on previous studies, Genetic models (GP and GEP) in the simulation and prediction of rainfall-runoff, water table depth variations, precipitation, suspended sediment, evaporation, lake water level variations, reservoir operation, water quality, water demand, flood routing, and streamflow have performed better than ANN, ANFIS, and SVM models (Kisi & Shiri, 2011;Shiri & Kişi, 2011;Kisi et al, 2012;Al-Juboori & Guven, 2016).…”
