Sažetak
Estimating discharge in tidal rivers presents a complex challenge, owing to their dynamic and ever-changing nature. These areas are influenced by multiple factors, including tidal range, wind, atmospheric pressure, and freshwater inflows, causing frequent fluctuations in water levels and discharges. As complex flow patterns and strong turbulence are common for tidal rivers, traditional methods of measuring discharge (such as current meters and stream gauges) are considered inefficient and result in unreliable data. Therefore, more adequate methods are required for estimating discharge. The machine learning approach is one of them. The current study employed a Long Short-Term Memory (LSTM) model that was optimized using grid search cross- validation and applied to simulated data of four water stages and a single discharge station in the Neretva River estuary located in Croatia. The study’s results demonstrated the model’s ability to estimate discharge in low and high-flow conditions accurately. A comparison between LSTM and a simple Multiple Linear Regression (MLR) model clearly shows the improvement in LSTM results for every range of discharge values. This study advances the ability to predict and obtain partial control over discharge in a tidal river by offering crucial insights for more effective environmental and flood management strategies.
