“…4a). Taniguchi and Fukuo (1996) found an effect of seiches on groundwater discharge into Lake Biwa, Japan. They found that the dominant periods of fluctuations of the groundwater seepage rate observed in Lake Biwa agreed well with those of the fluctuations of the water levels in the lake, which were calculated numerically by a finite element method.…”

“…Quantitative estimation of fluxes of recharging or discharging water provides fundamental information. To date, fluid fluxes were estimated in various environments, such as lakes [e.g., Shaw et al , 1990; Taniguchi and Fukuo , 1996], coastal zones [e.g., Cable et al , 1996; Moore , 1996; Spinelli et al , 2002; Taniguchi et al , 2002], submarine hydrothermal areas [e.g., Schultz et al , 1992, 1996; Cooper et al , 2000], and accretionary prisms in subduction zones [e.g., Carson et al , 1990; Tryon et al , 2001], with seepage meters, diffuse flowmeters, piezometers, and by chemical tracer methods.…”

Thermal response of sediment with vertical fluid flow to periodic temperature variation at the surface

[1] Characteristics of thermal responses of sediment with vertical fluid movement to periodic temperature variation at the surface were examined using a one-dimensional analytical solution. The amplitude of the thermal response decays exponentially, and the phase is delayed linearly with increasing depth, but they depend on the direction and velocity of vertical fluid flow, thermal diffusivity of fluid-saturated sediment, and period of surface temperature variation. To examine general characteristics of the thermal response, we defined two nondimensional parameters related to thermal diffusivity of fluid-saturated sediment, vertical fluid flow velocity, period of the surface temperature variation, and specific penetration depth at which the amplitude of the thermal response decays to e À1 of that at the surface. Analysis using these nondimensional parameters shows that there are three heat transport regimes for downward flow: (1) heat transport strongly governed by advection, (2) heat transport strongly governed by conduction, and (3) transition between these regimes. For upward flow, there are also three heat transport regimes: (1) balance of heat transports by advection and conduction, (2) heat transport strongly governed by conduction, and (3) transition between these regimes. The analytical solution is used to estimate the downward fluid velocity and thermal diffusivity of sediment from temperatures measured by long-term temperature monitoring at a site of seafloor hydrothermal circulation.Citation: Goto, S., M.

“…Seepage meters were developed originally by engineers studying leakage of canal bank linings (Israelson and Reeve 1944) but were largely ignored by the scientific research community until the 1970s when Lee (1977) demonstrated their effectiveness in evaluating groundwater seepage along shorelines. Since then, different forms of the seepage meter have been used with varying degrees of success in many freshwater and marine environments (e.g., Bokuniewicz 1980Bokuniewicz , 1992Prepas 1989, 1990;Belanger and Montgomery 1992;Reay et al 1992;Libelo and MacIntyre 1994;Cable et al 1996;Gallagher et al 1996;Taniguchi and Fukuo 1996;Cable et al 1997a,b;Corbett et al 2000;Chanton et al 2003;Cable et al 2004). The simplicity of seepage meter design and deployment makes the device simultaneously attractive for field work and the bane of the researcher.…”

Seepage meters, like most benthic flux chamber techniques, come with inherent concerns about how their presence may alter the environment and flow regimen of the benthic boundary layer and underlying sediments. Flow due to wave and current movement across topographic features induces a downward and upward flow field within the sediments surrounding the feature. We found this Bernoulli-induced flow is a real, but maybe minor, component of measured advection using seepage meters. This study was conducted in a Florida coastal lagoon to test the physical forcing mechanisms that may influence seepage measurements from sediments. Calculated Bernoulli seepage was within the measured background (~1 to 2 cm day -1 ) expected from seepage meters when a plastic barrier beneath the device is used to inhibit natural seepage contributions. Nearby seepage measurements made with Lee-type seepage meters placed directly in the sediments ranged from 1 to 12 cm day -1 . Thus, when seepage flow is very slow from sediments, Bernoulli-induced seepage may obscure the measurement. However, this study demonstrates that seepage in the Indian River Lagoon must be driven by forces other than Bernoulli-induced (pumped) flow. Suggestions for these forcing mechanisms highlight the uncertainty of the water source(s) in seepage measurements. In these Florida lagoon sediments, bioirrigation and terrestrial groundwater inputs are the most likely drivers, depending on distance from shore, benthic community composition, and continental recharge. Seepage measurements can be an excellent measure of advection in shallow-water marine sediments if Bernoulli-induced seepage is taken into account either experimentally or calculated based on local hydrographic and meteorological data.
