    The difference in height of the fluid between the two arms of the U-shaped tube is the same as the maximum intermediate height of a siphon. When used to measure pressures other than atmospheric pressure, a siphon barometer is sometimes called a siphon gauge; these are not siphons but follow a standard U-shaped design [58] leading

    Water may be supplied using gated pipe, siphon and head ditch, or bankless systems. The speed of water movement is determined by many factors such as slope, surface roughness, and furrow shape, but most importantly by the inflow rate and soil infiltration rate. The spacing between adjacent furrows is governed by the crop species, common ...
