| Abstract | Salinity intrusion plays an important role in human being, including the effects to the water supply for agriculture and domestic. Although this field of study drew the attention of scientist from a long time ago, using Artificial Neural Networks (ANNs) for prediction salinity distribution in the estuary is still rarely been done. Two neural network software packages (EasyNN and WinNN32) are presented in this study for forecasting salinity twelve hours ahead at six potential water abstraction locations along the West Pearl River Estuary. The data used for training and testing neural networks by these packages came from the results of a previous study using the three-dimensional hydrodynamic model RMA. The results for different types of ANNs applied by EasyNN and WinNN32 are compared. The WinNN32 with quick-prop algorithm was found more suitable for the salinity prediction than the EasyNN. The results also indicate that with appropriate structures, ANNs can give high performance for salinity prediction in estuary. |
