it is equal to the full depth and the I unload it is equal to that
of a rectangular incision that has an equal ampleness to the depth of
water that flows on at times the incision of V, both the being
measured in the same unity, therefore
      ____ ____ ____
  C \ / H^3 happens x C H x \ / H^3 that equalizes C \ / H^5.

However, the C you continue they will vary from that for the
rectangular incision to give an accurate result.

The formula of Cotterill for the I unload standing cubic for minute
it is
               _______
  16 C of x x B \ / 2g H^3s

when B = the width of standing incision and H = water's height in
feet and you/he/she can be applied to any proportion of incision. When B =
2H, or, a 90 incision, C = .595 and the formula it becomes
          ____
  152.4 \ / H^5,

and when B = 4H, or, an incision that contains an angle of 126 
51' 36", C = .62 and the formula you/he/she is written then
        ____
  318 \ / H^5.


The measurements of the depth of the water above of the incision
you/he/she should be taken by a hook-indicator of level, as when a rule or indicative of level-blackboard
the speed of the water is used it causes the second to rise as
it comes into contact with the edge of the tool that measures
and an accurate reading easily is not obtainable, and, subsequently,
