Abstract Sediment transport is a normal phenomenon in rivers and streams, contributing significantly to ecosystem production and preservation by replenishing vital nutrients and preserving aquatic life’s natural habitats. Thus, sediment transport prediction through modeling is crucial for predicting flood events, tracking coastal erosion, planning for water supplies, and managing irrigation. The predictability of process-driven models may encounter various restrictions throughout the validation process. Given that data-driven models work on the assumption that the underlying physical process is not requisite, this opens up the avenue for AI-based model as alternative modeling. However, AI-based models, such as ANN and SVM, face problems, such as long-term dependency, which require alternative dynamic procedures. Since their performance as universal function approximation depends on their compatibility with the nature of the problem itself, this study investigated several distinct AI-based models, such as long short-term memory (LSTM), artificial neural network (ANN), and support vector machine (SVM), in predicting sediment transport in the Johor river. The collected historical daily sediment transport data from January 1, 2008, to December 01, 2018, through autocorrelation function, were used as input for the model. The statistical results showed that, despite their ability (deep learning and machine learning) to provide sediment predictions based on historical input datasets, machine learning, such as ANN, might be more prone to overfitting or being trapped in a local optimum than deep learning, evidenced by the worse in all metrics score. With RMSE = 11.395, MAE = 18.094, and R 2 = 0.914, LSTM outperformed other models in the comparison.

Potential environment and socio-economic impact of biofuel production in Malaysia: a preliminary review

Carbon monoxide (CO) is one of the dangerous air pollutants due to its negative impact on human health. Therefore, accurate forecasting of CO concentration is essential to control air pollution. This study aims to forecast the concentration of CO using sequences to sequence models namely convolutional neural network and long short-term memory (CNN-LSTM) and sequence to sequence LSTM (seq2seq LSTM). The proposed forecasting models are validated using hourly air quality datasets from six monitoring stations in Selangor to forecast CO concentration at 1 h to 6 h ahead of the time horizon. The performances of proposed models are evaluated in terms of statistical equations namely root mean square error (RMSE), mean square error (MAE) and mean percentage error (MAPE). CNN-LSTM and seq2seq LSTM model excellently forecast air pollutant concentration for 6 h ahead with RMSE of 0.2899 and 0.2215, respectively. Additionally, it is found that seq2seq LSTM has slightly improved CNN-LSTM indicates the effectiveness of the architecture in the forecasting. However, both proposed architectures illustrate promising results and are reliable in the forecasting of CO concentration.
