Predicting harmful algal blooms is crucial for mitigating environmental and economic damage. This study shows that the Long Short-Term Memory (LSTM) deep learning model significantly improves prediction accuracy for algal blooms in South Korean rivers.

Area of Science:

  • Environmental Science
  • Data Science
  • Artificial Intelligence

Background:

  • Harmful algal blooms (HABs) cause significant environmental and economic damage annually.
  • Current physical prediction models for HABs are limited by complex variable relationships and high costs.
  • Improved advance warnings are essential for managing HABs.

Purpose of the Study:

  • To evaluate the effectiveness of deep learning models, specifically Long Short-Term Memory (LSTM), for predicting harmful algal blooms.
  • To compare the performance of LSTM against other deep learning models (MLP, RNN) and traditional regression analysis (OLS).
  • To establish a reliable method for short-term HAB prediction in South Korean rivers.

Main Methods:

  • Utilized a newly constructed dataset of water quality and quantity from 16 dammed pools in four major South Korean rivers.

  • Employed three deep learning models: Multilayer Perceptron (MLP), Recurrent Neural Network (RNN), and Long Short-Term Memory (LSTM).
  • Performed short-term (one-week) predictions of chlorophyll-a concentrations, a proxy for algal activity, and compared results using Root Mean Square Error (RMSE) against Ordinary Least Squares (OLS) regression.

    • Main Results:

    • The LSTM model demonstrated the highest prediction accuracy for harmful algal blooms.
    • All tested deep learning models outperformed the traditional OLS regression analysis.
    • The study successfully predicted chlorophyll-a levels, indicating potential for HAB forecasting.

    Conclusions:

    • Deep learning models, particularly LSTM, show significant potential for accurate and efficient harmful algal bloom prediction.
    • LSTM offers a promising alternative to traditional methods, overcoming limitations in complexity and cost.
    • This research highlights the applicability of AI in environmental monitoring and management for HABs in South Korea.
