Water quality deterioration can be caused at downstream in dry season due to insufficient flow. This demands additional outflow from dam since some extent of deterioration can be attenuated by dam reservoir operation to control outflow considering predicted water quality. A seasonal occurrence of high ammonia nitrogen (NH3-N) concentrations has hampered chemical treatment processes of a water treatment plant in the river basin. Monthly flow allocation from upstream dam is important for downstream NH3-N control. The models for the forecasting of NH3-N concentration at intake station are developed by considering dam outflow and river water quality such as alkalinity, temperature, and NH3-N of previous time step. |
