The coefficients k and x in the linear Muskingum equation are determined by the least-squares method (LSM). A routing scheme is proposed for situations where the storage and weighted flow relationship is nonlinear. Although the routing coefficients in the nonlinear equation are not determined by LSM, an alternative working method is proposed. Another simple method for nonlinear flood routing is proposed which is called herein the segmented-curve method. The coefficients in this method are determined by LSM. This method involves only a slightly more work than is required in the linear Muskingum method which is inaccurate in nonlinear problems. © 1978.
