In reservoir routing, the storage is a unique function of outflow discharge, S = f(Q).
However, in channel routing the storage is a function of both outflow and inflow discharge and hence a different routing method is needed from muskingum method of hydrological channel routing storage is given by,

The Muskingum method of flood routing is a hydrologic channel-routing method used to estimate the flood wave attenuation in a river channel. It is a simple and widely used method for flood routing, especially for small to medium-sized river basins.
The method is based on the principle of conservation of mass and momentum and assumes that the flood wave propagates at a uniform velocity along the channel. The Muskingum method divides the channel into a series of reaches, each characterized by a storage coefficient, a weighting factor, and a time lag. The storage coefficient represents the amount of water that can be stored in the reach and the weighting factor represents the proportion of the inflow that is routed downstream.
The Muskingum method is a hydrologic channel-routing method, which means that it is based on the water balance equation and does not consider the hydraulic properties of the channel. It is a lumped parameter method, which means that it represents the channel as a single reach and does not account for the spatial variations in channel characteristics.
The Muskingum method is a complete numerical solution of the Muskingum equation, which is a linear partial differential equation that describes the propagation of flood waves in a channel. The Muskingum equation can be solved using numerical methods such as the finite difference method or the explicit Euler method.
In conclusion, the Muskingum method of flood routing is a hydrologic channel-routing method that uses the Muskingum equation to estimate the flood wave attenuation in a river channel. It is a simple and widely used method for flood routing, especially for small to medium-sized river basins.
