چکیده مقاله
Numerical models are useful tools for understanding and predicting complex hydrodynamic processesoccurring in lakes This study aims to investigate the capability of a one dimensional hydrodynamic model GOTM to simulate the water temperature of Lake Urmia This study uses a two equation one dimensionalturbulence model based on k ε equations GOTM is a one dimensional model that simulates the verticaldistribution of temperature, salinity, and other thermodynamic and chemical quantities The air sea surfaceforcing is determined based on meteorological variables such as wind speed, temperature, humidity, etc obtained from a combination of weather stations and ERA5 reanalysis data The model is calibrated usingin situ water temperature data collected at four stations Comparisons of the observed and simulated resultsindicate that the model accurately predicts the water temperature Finally, the impact of climate changeunder the SSP2 4 5 scenario from the CMIP6 data and GFDL ESM4 model on the lake temperature untilyear 2100 is evaluated The results were analyzed by Sen's Slope and Mann Kendall test to reveal the longtermtrend of lake temperature changes The results of Sen's Slope and Mann Kendall test show that eventhough the temperature changes in all months are not the same, an upward temperature trend is predictedin most months
