Abstract

Abstract

Given the complex process of salt tide upstream in the estuary area,and it's difficult to control the timing of daily hourly freshwater intake by coastal water plants,a statistical model for hourly water intake evaluation based on the dynamic index of the estuary area was established by using the Logistic method and considering the historical salinity memory effect,to realize the hourly water intake prediction of waterbodies with less than 0.5‰ salinity in the estuary area.Taking the Modaomen estuary of the Pearl River as an example,the accuracy of the prediction results of the model was found higher than 90%,which realized the reliable prediction of hourly water intake the next day,and provided an effective reference basis for the water plants to prepare and stop water intake in time.The model had a certain reference significance for the risk assessment of hourly water intake with low salinity in other estuaries.
