Modeling Tidal Signals Enhanced by a Submarine Spring in a Coastal Leaky Aquifer System

摘要：

This paper presents an approximate analytical solution for describing the tidal signal propagation in a coastal leaky confined aquifer system with a submarine spring. The system comprises a confined aquifer, an unconfined aquifer and a semipermeable layer between them. The aquifer and the semipermeable layer extend seaward and landward Infinitely. The elastic storage of the semipermeable layer is neglected. The spring Is represented by a highly-permeable round column which completely penetrates the semipermeable layer. The error of the approximate analytical solution is analyzed and is less than 4％ if the spring radius is less than one-tenth of the distance between the spring center to the coastline. Numerical tests demonstrated that the springs location can be identified by using the observed data of tidal groundwater head fluctuations from inland wells.
