Analysis of basin irrigation performance with variable inflow rate

Basin irrigation systems were designed for a constant flow rate. The operation of the designed system was simulated using the zero-inertia model of surface irrigation. The performance of the system was obtained for modified design flow rates. Three patterns of flow variation — sinusoidal, initially low then high, and initially high then low — were studied. The average of a variable flow rate in a given simulation equalled, was less than and...
