Title

Multi-objective calibration of conceptual hydrological model by AMALGAM algorithm

Pages

  161-175

Abstract

 Background and Objectives: One of the ways to predict and estimate the amount of runoff from rainfall is the use of hydrological models. Calibration process is a critical step which should be carried out carefully to optimize the model parameters. Multi-objective optimization algorithms as one of the most important and practical topics in various fields of study could be employed to achieve a reasonable calibration. The purpose of these algorithms is to determine the values of model parameters to find the best possible solution and achieve different goals. Materials and Methods: In this study, Multi-objective optimization algorithm (AMALGAM) used to calibrate conceptual daily hydrologic model (MILC). MILC model employs the Soil Conservation Service-Curve Number method for abstraction (SCS-CN) for estimation of losses, the geomorphological Instantaneous Unit Hydrograph (GIUH) for routing of rainfall excess of catchment. This paper applies a four-objective calibration strategy focusing on peak flows (NSE), low flows (TRMSE), water balance (ROCE) and flashiness (SFDCE) to parameter estimation of MILC model. After calibration process, a trade-off point extracted from Paretofront was selected to include the appropriate values of all four objectives simultaneously. This point is applied to verify the validation period. Results: The obtained values during the validation period (0. 71 ≤ NSE ≤ 0. 78) indicate that the MILC model has good performance to simulate the amount of peak flows but according to ROCE and SFDCE values it has weak performances to simulate the balance water and median flow respectively. Conclusion: The values obtained for the TRMSE target function during the periodic verification period were 1. 22 to 1. 22 (TRMSE = 0 in optimal mode), which indicates that the simulations are suitable for low flows. Multi-objective optimization algorithm for the automatic calibration process of rainfall-runoff model, due to the use of multiple objective functions that target each part of the hydro graph of the basin, challenges the model in simulating all current flows in the basin. This issue shows the importance of using multi-objective algorithms to calibrate hydrologic models. Also, the intelligent selection of multi-objective functions in the calibration process of the model plays a key role in understanding the model more fully by using multi-objective algorithms instead of single-objective for the calibration process.
