Seepage meter efficiency in highly permeable settings source data (2020)

Efficiency of seepage meters, long considered a fixed property associated with the meter design, is not constant in highly permeable sediments. Instead, results from this study indicate that efficiency varies substantially with seepage-bag fullness, duration of bag attachment, depth of meter insertion into the sediments, and seepage velocity. Efficiency also varies substantially in response to variable hydraulic conductivity. The first worksheet titled "Literature efficiency" presents seepage-meter efficiency values from the literature to show the progression of efficiency versus time. The remaining 7 worksheets present time-series data showing seepage-meter efficiency related to several different tests: (1) flow response to a series of bag attachments, (2) effect of bag fullness during upward flow at several seepage rates, (3) efficiency response during long bag attachments at a range of seepage rates, (4) efficiency during upward and downward seepage at a range of seepage rates, (5) efficiency in response to different insertion depths of the seepage cylinder, (6) efficiency in response to variable hydraulic conductivity, and (7) efficiency reduction during a prolonged seepage-meter installation.
