Time Lag Solution of the Muskingum Flood Routing Equation

Use of time lag in the Muskingum method of flood routing is explained by considering some specific examples. Time lag method removes undesirable predicted results which are obtained by the conventional method. A method is also proposed for calculating the time lag. The examples which have been considered are of floods which can be described in algebraic terms; the method is however of general application and can be adapted for numerical computation.
