    calculating gradient and direction

    I need to do a series of 3-point problems. I have a series of 3 water level elevations taken on the same day over several years. I would like to know what is the water level gradient and direction of water travel toward the low point of the plane.; e.g., 0.0012 ft/ft toward 275o. For each date of measurement, example data are attached.

    Thanks.

    Jepalmer,

    To find the angle, use this formula in E2 then copy down

    =DEGREES(ATAN(C2/B2))

    HTH,

    Hi Maud

    So far there was only sin2(x) + cos2(x) partial answer proposed. Next we'll have (O/H)-feld jokes.
