Aquifer Response to Stream-Stage Fluctuations: Field Tests and Analytical Solution for a Case Study of the Yangtze River in Wuhan, China

In this paper, field hydrological monitoring tests and an analytical solution for the aquifer response (i.e., groundwater head) to stream-stage fluctuations are presented through a case study of Yangtze River in Wuhan, China. A sinusoidal equation stream water level over time is proposed verified by results. Based on classical 1-D ground flow equations, new model was analyze confined fluctuations. The head can then be calculated embedding fluctuation into model. Field data three years from 2017 2019 were compiled evaluate results show that predicted matches well with data. prediction error (about 8%) much lower than previous 26%). This paper presents improved satisfying capability predict fluctuation. applied models (such as MODFLOW, FEFLOW, etc.). provide valuable resource underground practical engineering riverside area, especially first terrace River, dewatering design foundation pit area.
