ABSTRACT
Looking beyond a purely scientific discussion of hydrology, the authors of this volume emphasize that mankind needs to recognize the urgency of the situation in which our water is threatened. Providing a comprehensive overview of the broad and complex field of hydrology, the book explores the water cycle, its various components, and its interaction

application of the law of single recession is for determining the total volume of water stored as groundwater at a given moment. If the recession law f(t) of a watershed is known, it is then possible to evaluate its storage capacity by integrating f(t) over a time interval [t,f]. The volume of water available at time t is given by the following equation:

textbook on statistics for details.) Example: Because a anthropogenic intervention had altered the Viege watershed in 1964, the peak discharge series is separated into two samples: x , x,…., x (peak discharge 1922 to 1963), and y , y,…., y (peak discharge 1964 to 1996).
(97.5%) = 1.72. Given that 1.31 is less than 1.97, we cannot reject the null hypothesis that the variances are equal and we can apply the Student test for the two samples. Since we know what kind of effects result from dam construction, we would expect to see a significant reduction in discharge in the second sample, which leads us to formulate the alternative assumption to test the homogeneity of the samples starting
