By using different input combinations consisting of monthly Inflow - Lost flow (I), Precipitation (P), Evaporation (E) and Outflow (O), efforts were made to estimate the change in water level (L). Performance of models established was evaluated using root mean square error (RMSE), mean square error (MSE), mean absolute error (MAE) and coefficient of determination (R-2). According to the results of models, epsilon-SVR model was obtained as the most successful model to estimate monthly water level of Lake Beysehir.en10.1007/s11269-014-0773-1info:eu-repo/semantics/closedAccessAdaptive network-based fuzzy inference systemArtificial neural networksLake BeysehirParticle swarm optimizationSupport vector regressionWater levelArticle281347474763Q1WOS:000342448400021Q1
