This paper uses a physical model to check the reliability of the numerical modeling proposed by Chen. As an example, this paper deals with a horizontal well pumpage underneath a river bed, or a vertical well adjacent to the bank of the river. We use the numerical method of Chen to simulate the groundwater flow pattern of the physical model.
