“…Up to now, several different analytical models have been developed including Hantush (1967), Rao and Sarma (1984), Latnopoulos (1985), Rai and Singh (1995), Rai and Manglik (1999) and Rai et al (2006). Those analytical solutions require either constant (Rao and Sarma, 1984) or continuous analytical functions (Latnopoulos, 1985;Rai and Singh, 1995) or rather complicated piecewise functions (Rai and Manglik, 1999;Rai et al, 2006).…”

“…On the ground surface, constant flow rate boundary condition is used where the constant denotes the rainfall infiltration rate [LT −1 ], which is assumed to be distributed uniformly over the inland area and averaged over 1 year or longer period (Glover, 1960; Hantush, 1967; Rao and Sarma, 1984; Zissis et al , 2001).…”

Abstract:This article investigates the quantity of submarine groundwater discharge (SGD) from a coastal multi-layered aquifer system in response to constant rainfall infiltration. The system comprises an unconfined aquifer, a leaky confined aquifer and an aquitard between them and terminates at the coastline. An approximate analytical solution is derived based on the following assumptions: (i) flow is horizontal in the aquifers and vertical in the aquitard, and (ii) flow in the unconfined aquifer is described by nonlinear Boussinesq equation. The analytical solution is compared with numerical solutions of the strictly two-dimensional nonlinear model to validate the model assumptions used for the analytical solution. The SGD from the leaky confined aquifer increases with the inland rainfall infiltration recharge and the specific leakage of aquitard. The maximum SGD ranges from 1Ð87 to 10Ð37 m 3 per day per meter of shoreline when rainfall infiltration ranges from 18Ð2 to 182 mm/year and the specific leakage of aquitard varies from 10 9 to 10 1 l/day.

“…Most of the solutions are based on the assumption that the rate of recharge is constant and the base of the aquifer is impermeable. (Glover, 1961;Hantush, 1967;Hunt, 1971;Rao and Sarma, 1984). However, rate of recharge with which infiltrated water joins saturated zone at the water table largely depends on the nature of infiltration rate, which is known to vary with time.…”
