Description:
In order to better understand the nature of pore pressures and seepage
beneath a levee in the Sacramento River Delta, and to evaluate the
effectiveness of newly installed subdrains, four
Slope Indicator 50-psi vibrating
wire piezometers are utilized. One piezometer measures water levels in the
adjoining river, while 2 others read piezometric pressures below the levee
center line and the toe. The remaining piezometer is used to measure
barometric pressure. Data is collected every hour and corrected for
barometric pressure using a Campbell Scientific CR10X datalogger. Data is
downloaded periodically using a handheld PDA and analyzed to determine the
effects of tidal and elevated water levels on the levee.
