What is it about?
his paper presents a methodology for reservoir routing in general and for arid region in particular. The proposed methodology combines the mass conservation equation of the dam reservoir, the discharge equation of the dam outlet devices, and a dimensionless depth–volume equation to calculate the outflow hydrograph downstream of the dam for a given inflow hydrograph. The proposed model is solved numerically using first- and second-order Euler finite difference schemes and shows pretty good agreement when compared with analytical solution of a specific example in the published literature and with the traditional (modified puls) method (RMSE is 0.668, 0.673, and 0.94 m3/s respectively for the time step of 300 s).

Why is it important?
The paper suggests that the design of reservoir in arid region should consider an empty reservoir routing, which leads to economic design of the downstream flood channel.
