Hello everyone. Please I have a large discharge data set that I want to use to calculate the x and k values of the Muskingam method of flood routing. Can anyone suggest a computer model to me that i can use for this calculation considering the fact that x value range from 0.1-0.3, which means that I have to do lots of trial and error before I can get the desired slope for the graph (xI+(1-x)O) (cfs) for several guaging stations.
