Abstract : Our research centers on estimating the water temperature of Fontaine de Gazelles Reservoir Dam by analyzing air
temperature, relative humidity, solar radiation, atmospheric pressure, wind speed, and precipitation. These variables
collectively impact water temperature, reflecting the thermal environment, water vapor content, solar energy, air density,
wind-induced processes, and precipitation cooling. We employ Multiple Linear Regression (MLR) and Generalized
Regression Neural Networks (GRNN) models for accurate estimates. MLR captures linear dependencies among climate
variables, while GRNN model complex nonlinear relationships. Trained on historical data and real-time measurements, both
MLR and GRNN demonstrate strong capabilities. MLR achieves high Nash-Sutcliffe Efficiency (0.991 to 0.997) and low
Root Mean Squared Error (0.406 to 0.625), while GRNN achieves similar values. Both models consistently exceed a
coefficient of determination R2equal 0.99, indicating a robust correlation, and display low Mean Absolute Error (0.236 to
0.391), affirming their accuracy. This attests to MLR and GRNN's reliability in estimating water temperature for the
Fontaine de Gazelles Reservoir Dam.
