This study was conducted to evaluate the border irrigation method using power<br/>advance approach of the volume balance model. Specifically, it aimed to develop a<br/>computer program that computes the application efficiency, field losses and recommended stream size. <br/><br/>Infiltration depth function and net depth of water applied established before<br/>irrigation using equation z = kt. Different infiltration depths functions were established<br/>using the formula, z = kt" a + ct. Net depth of water to be applied was also determine<br/>using the formula dn = (FC-CSM )As D. Iteration was done to determine the correct<br/>value of the subsurface shape factor, o, and slope of infiltration equation, r. The values<br/>of co, and r, aided in the prediction of advance distance, L along the border using the<br/>Equation Lqot/oyw+ cwk(t" + cwt/(r+l). The pump used during field experiment<br/>was two-inch gasoline self-priming pump.<br/><br/>The derived equations from the field experiment were use in the development of<br/>computer program and written in Visual studio 2015, named Border Irrigation Support<br/>System (BISS).<br/><br/>The result of the study showed that, the net depth of water to be applied was 5.68<br/>cm, and the infiltration depth equations are z = 0.0087800<br/>802<br/>4 0.00213t, z<br/><br/>0.0087g0<br/>50802<br/>4 0.00360t and z= 0.00878/9<br/>50802<br/>4 0.00457t Equations to find the value of L, were established; L=0.06953t4/(0.16529 + 0.00703,0"0<br/>02<br/>4 0.00150tu.) for 0.17 m'/min pump discharge, L= 0.115794/(0.22446 + 0.006944,""<br/>0<br/>00 4 0.00248tu.)<br/>for 0.34 m'/min pump discharge and L = 0.15422t4 / (0.26657 + 0.00680£,"<br/>0<br/>0<br/>2<br/>for 0.80 m'/min pump discharge. The predicted advance distances were<br/>close to the observed advance distances with 0.03m to one-meter discrepancy. The result<br/>shows that, 0.80 m'/min pump discharge gives the highest application efficiency of<br/>50.93% and 0.17 m'/min pump discharge give the highest deep percolation ratio and tail<br/>water r:atio with r.98% aqd ~.J6% respectively. In addition, 0.80 m'/min pump<br/>discharge give a high R value of 99.8%. BISS manual develop for easy operation and<br/>utilization of the computer program. |
