Methods for Solving Algebraic Equations and Their Systems,near algebraic equations the bisection, false position, Newton, fixed point iteration and some hybrid methods are described. Application of these methods is shown for typical open channel problems, like computation of the normal depth, critical depths or the depth of water over sharp-crested weir. N

Numerical Solution of Ordinary Differential Equations,umerical methods as well as a general approach for approximating formulas is described. The basic numerical methods applicable for open channel flow (i.e. for non-uniform grid) are developed. The problem of accuracy and stability including A-stability is discussed. Time integration of the systems of

Steady Gradually Varied Flow in Open Channels,prismatic channels, the ordinary differential energy equation is proposed. It is showed that the standard step method used for computation of the flow profiles in natural channel is in fact the differential energy equation integrated numerically with the implicit trapezoidal rule. Consequently this

Book 2010uman l- ing. The free surface ow, which takes place in the oceans, seas and rivers, can be still regarded as one of the most complex physical processes in the environment. The rst source of dif culties is the proper recognition of physical ow processes and their mathematical description. The second
