hydrologic model calibration

Hydrologic model calibration involves adjusting a computer simulation to accurately reflect real-world water movement, such as rainfall, runoff, and streamflow. By fine-tuning parameters like soil absorption or evaporation rates, the model's outputs match observed data from measurements or gauges. This process ensures the model reliably predicts how water behaves in a specific area, aiding in water resource management, flood forecasting, and environmental planning. Calibration improves the model's accuracy, making it a valuable tool for informed decision-making about water-related issues.
