Latitude-Longitude Conversion to Feet (323 words)
A minute of latitude is equal to one nautical mile, or 6076 feet; thus, a second of latitude (6076 divided by 60) is 101 feet, 3 inches.
Conceptually and practically, latitude is the same no matter where you go on earth; however, in reality it varies from 69.41 statute miles per minute at the poles to 68.70 statute miles per minute at the equator due to the earth bulging slightly from its rotational spin.
Finally, 60 degrees North (southern border of the Northwest Territories), a degree of longitude is 34.67 statute miles, 3051 feet (930 meters) per minute, 50.85 feet (15.5 meters) per second.
G1681 Measuring Irrigation Water in a Ditch, Stream or Reservoir, MU Extension (1673 words)
One cubic foot per second is a flow of water equivalent to a stream 1 foot wide and 1 foot deep flowing at a velocity of 1 foot per second.
Multiply the velocity in feet per second by the estimated stream cross-sectional area in square feet to determine the flow rate in cubic feet per second.
A second method is to measure the depth of water next to the weir, but far enough to the side of the crest to be in still water.
