UM-13 : Kalinin-Milyukov method of flood routing

Abstract

A method of flood routing using theory proposed by Russian Scientists Kalinin and-Milyukov on flood wave transformation is described in this report. Assumption of a single valued stage discharge relationship in the simplified flood routing method does not provide for attenuation of a flood wave. If one takes into account even approximately the dynamic nature of the stage and discharge relationship a more appropriate flood routing method can be evolved. Russian scientists included the water surface slope also into the relationship and approximately included the dynamic nature of the relationship. This simple method aims at dividing a river reach into a number of echaracteristic length and route the flood.

Computers for computation of the characteristic length and routing of flood have been developed and implemented in VAX-11/780. This users manual explains use of these programmes. In order to illustrate the usage of these programmes a flood experienced during the year 1973, in the river Sabarmati at Dharoi is routed upto Ellisbridge and compared with that of observed one. The plots indicate a good performance of this method.
