A note on the Muskingum flood‐routing method

An exact method of solution of the flood-routing equation, when the storage is a linear function of weighted inflow and outflow, is developed. This operation is shown to be equivalent to routing a multiple of the inflow through reservoir storage and subtracting the excess inflow. Modified coefficients for the Muskingum equation are developed which do not depend on the routing interval being small relative to K.
