Abstract
Flood subject represents a danger subject for many people and countries which have rivers like Iraq, thus to thought in ways of flood routing & assess out flow discharge river. Flood routing divided into two kinds, hydraulic & Hydrology. Each one of them has properties & features. One of the most important method of routing is the Linear and Non-Linear Muskingham flood routing method. Baiji station has been selected as a case study because outflow & inflow discharges data for a constant period are available. Linear and Non-Linear Muskingham Method is applied using modern computer language ( Mat Lab – Version 6.5 – Release 13). It working with Windows environmental. For each method, we do two programs: the first is to calculate the variables (X,K,m) and the second is to calculate outflow from the Baiji station. Results of the first program for Non-Linear is analyzed in statistical program (SPSS) to calculate linear correlation factor. Also a new method are created (Mixing method) between Linear & Non-Linear, then separate it in another program & use statistical program for it. With insert all necessary statistical graphs and discharges comparisons graphs. Results of Linear Muskingham method is better than Non-Linear & more adequate and close to real data, also when it is used in the third method, it was the best. Results for Non-Linear has been canceled when it use in third method.
