<br />The integral which appears in this expression has been extensively tabulated. <br />(4) (5) (6) It is called the "Probability Integral". Charts of a general nature <br />can be constructed from such expressions. A sample is given in figure 1. <br /> <br />~ <br /> <br />By integrating this expression with respect to time the total depletion of the <br />river can be obtained in the form: <br /> <br />\ \ I dt <br /> <br />,0 <br />Qt <br /> <br />: l- <br /> <br />2 <br />.r; <br /> <br />Xl <br /> <br /> <br />~ j4at" <br />-u~ <br />e du <br /> <br />o <br /> <br />; (,:': )"r:~' <br /> <br /> <br />, Xl <br /> <br />~ <br /> <br />du . . .
