- Using literal values, determine the time interval dt during which
the water level rises a distance dh
Thus, with C = numerical constant in the discharge equation,
-Q^HP
(34)The right side of this equation is not amenable to direct integration. Consequently, the
only feasible way of computing the time is to perform an approximate integration.
- Obtain the approximate value of the required time
Select suitable increments of /*, calculate the corresponding increments of /, and total the
latter to obtain an approximate value of the required time. In calculating Q 0 , apply the
mean value of h associated with each increment.
