The Muskingum model of routing a flood through a stream reach is expressed as O2 = K0I2 + K1I1 + K2O1, where K0, K1 and K2 are the routing coefficients for the concerned reach, I1 and I2 are the inflows to the reach, and O1 and O2 are the outflows from the reach corresponding to time steps 1 and 2 respectively. The sum of K0, K1 and K2 of the model is
