Calculating water flow

    I'm trying to figure out how some guy in a research paper did a particular calculation.

    Water flow rate was determined to be 5 x 10-6 m/second (or 0.432 m/day).

    "Using daily (24-h) integrated estimated seepage rates from these calculations and assuming this rate is characteristic of the water groundwater fluxes for a 200-m band, we estimate the discharge per unit length of shoreline at 3.4 × 10–4 m3/m.s (29 m3/m.day)"

    i just don't understand how he got from 0.432 m. day to 29m3 .m . day.

    cany anyone help with this?

    "Water flow rate was determined to be 5 x 10-6 m/second (or 0.432 m/day)."
    Water flow in metres per second? There's some missing data there e.g. that's a seepage rate through soil, not an actual flow rate in m³/sec.

    If you post the name of the paper and the author(s), I/we may be able to find it and see the problem in context.

I am so glad that you have never done anything, never carved a statue, or painted a picture, or produced anything outside of yourself! Life has been your art. You have set yourself to music.

    Oh sorry, should have included that

    it's:

    i meant seepage rate not flow rate.

    Got the paper - I'll take a closer look later. After a quick look, it appears that the method used is the subject of the paper i.e. the paper itself is the answer to your question. ;)

    Answers in the abstract or the last two lines of the conclusion so, no one reads the in-between bits :pac:
