نبذه عن الكتاب:



This is not an ordinary book on rainfall and runoff. All the general and working formulas

in this book are theoretically derived. The formulas are therefore globally and eternally

applicable, as long as the situations under consideration are within the assumptions and

limitations of the theory. This epitomizes the powerful nature of the physically-based

approach in hydrology. This book covers formulas for flow depth; flow velocity; average

flow velocity; wave celerity; average wave celerity; time of concentration; rising, equilibrium

and falling phases of a hydrograph; forward characteristic; rising, equilibrium and falling

phases of water surface profiles; duration of partial equilibrium discharge; and equilibrium

detention storage for flow on an overland plane, and flow in nine different channel shapes,

which are (i) circular, (ii) parabolic, (iii) rectangular (deep), (iv) rectangular (square), (v)

rectangular (wide), (vi) trapezoidal with equal side slopes, (vii) trapezoidal with one side

vertical, (viii) triangular, and (ix) vertical curb.
