Krupaseep?The Next Generation Seepage Meter

Abstract

jffffff KRUPA, S.L.; BELANGER, T.V.; HECK, H.H.; BROCK, J.T., and JONES, B.J., 1998. Krupaseep-The Next Gener ation Seepage Meter. Journal of Coastal Research, SI(26), 210-213. Royal Palm Beach (Florida), ISSN 0749-0208. ^M_^%* We designed, built and tested a new kind of seepage metering device to study the exchange of ground water and river ^2^5^S^5^ water at the bottom of streams and lakes. The dome-shaped seepage meter is fabricated from translucent polycar ^S^SS^^S^ bonate plastic. A flow meter, installed in a port at the apex of the dome, utilizes heat-pulse technology to measure ^^^^^^ real-time fluxes. Electronic data loggers record the flow, as well as water quality data, obtained by sensors located both inside and outside of the dome. Additionally, water quality samples are remotely extracted from inside and outside the dome for laboratory analysis. All real-time data is captured by on-shore computers. The new design eliminates problems such as induced anaerobic conditions and methane accumulation, which are inherent to the traditional, low-tech devices commonly used today. The data are quite promising and will allow, for the first time, a clear understanding of interactions between ground water and surface water, with an emphasis on water quality.
